Caelux is revolutionizing solar technology with their innovative perovskite-based solution that promises to increase solar panel efficiency by 5-6 absolute percentage points while maintaining cost effectiveness. From a small 8-person lab in East Pasadena to a 74-person company with a 50-megawatt demonstration line, Caelux is pioneering a new approach to solar panel manufacturing by working with existing manufacturers rather than competing against them. Topics Discussed: Evolution of the solar industry from 2008 to present day Strategic approach to commercializing new solar technology Impact of global market dynamics on solar panel pricing Energy security and domestic manufacturing trends Challenges in land use and solar adoption Future applications of perovskite technology   GTM Lessons For B2B Founders: Partner with giants instead of competing: Caelux chose to work with existing solar panel manufacturers rather than becoming a panel maker themselves. Scott explained, "The way to go and get this technology in the market embedded to the extent that it needed to be was to work with solar module companies, make their products better, and then we would have cheerleaders as opposed to competitors." This approach dramatically reduced their time to market and capital requirements. Use manufacturing as a development tool: Rather than staying in the lab indefinitely, Caelux leverages manufacturing assets for product development. Scott noted, "While folks can run maybe a couple dozen experiments a day, we can run hundreds of experiments a day by using manufacturing assets that then translate quite easily into this fully released product." B2B founders should consider how production infrastructure can accelerate their development cycle. Build downstream demand strategically: Caelux focuses on engaging asset owners and developers who will be the ultimate beneficiaries of their technology. Scott shared, "We want them to spec us in for next project. So even if module companies may be a little slow to adopt, we want to ensure that the folks that are writing the checks understand what's available." This creates market pull for their technology. Master expectation management: When deploying new technology, Caelux is deliberately transparent about potential challenges. Scott emphasized, "If anything, we're a bit too transparent. We tell people where the warts are and we say where the challenges are and own them. Because otherwise I think you're lying to yourself as a company and you certainly don't want to lie to customers. You get zero chances after that." Navigate the climate tech funding landscape: Scott revealed that true climate tech investors are rare, and many prefer speculative moonshots over companies with clear markets. He advised, "Mistakes need to be made because those are part of the learning cycle. It's just don't make company killer mistakes. Make small ones and then recover from them and then you can continue to evolve your product."

Solar Power is a key component of the push for a zero carbon energy sector, and to meet this demand scientists are pushing the boundaries of what new materials and technologies will make up the next generation of solar panels. The vast majority of solar panels currently manufactured today are made from silicon, which can reach efficiency levels of up to 24%. Efficiency is an extremely important factor of solar panels, as it measures just how much of the sun's energy is being converted into electricity. While solar panels have improved by leaps and bounds in recent years as investment has poured into the industry, there are hard limits with regards to what can be achieved with silicon. The best solar panels on the market right now are approaching those limits, and new gains become harder to achieve as they get closer. That is why research and development is now looking at Perovskite as the basis of the next generation of solar panel technology, especially when paired with other materials. Named for German mineralogist Lev Perovskite, these synthetic minerals have the potential to truly revolutionise solar technology. Expected to start coming onto the market in just a few years, some of the earliest solar panels made using perovskites as their basis are already exceeding the best silicon solar panels' efficiency. James Dorrian, Managing Director of EnergyEfficiency.ie, said, "It's great to see such promising trends in the the solar industry. Both from the ever growing interest people have in getting solar panels installed, and from new developments in solar technology." "Constantly pushing the envelope with solar technology is essential for encouraging new investment and to assure people that solar power is an essential part of the future of the energy sector." "Improved efficiency levels will make solar panels a better long-term investment, especially for solar PV systems where space is at a premium, such as domestic rooftop solar." There are two main types of perovskite solar cells: single junction cells made purely of perovskites and tandem cells where the perovskite works together with another semiconductor, usually silicon. Tandem Solar Cells essentially work by stacking two or more solar cells on top of one another; each optimised to absorb a different part of the wavelength of light. This is where researchers and manufacturers are placing their money on the next generation of solar panels. Perovskite-silicon tandem solar cells consist of a thin layer of perovskite on top of a silicon cell. The perovskite responds to the entire visible light spectrum, and even that near-infrared light which passes through it is absorbed by the silicon layer beneath and converted to electricity. Tandem solar cells have achieved efficiencies significantly greater than what has been seen using any single material, and lab results have already surged past 30% efficiency. LONGi Green Energy Technology currently holds the record for achieving 33.9% efficiency with a perovskite-silicon tandem solar cell in October 2023. While solar panels on the market never reach the same level of efficiency as cutting-edge lab tests, this is still an incredible foundation to build on. Indeed, the first full solar PV modules using Perovskite Tandem Solar Cells have already been manufactured just this year by a research team from the Fraunhofer Institute for Solar Energy Systems ISE using solar cells manufactured by Oxford PV. This solar module has an efficiency of 25%, the world's highest, a power rating of 421 watts, and covers an area of 1.68 square metres. This means that the first perovskite-silicon tandem solar PV modules being manufactured have a greater efficiency than the top-performing silicon solar panels on the market today. In addition, this panel was made using equipment already used in mass manufacturing today, which only needed modification for the new process. This means that the mass production of such solar panels might not be far off. Perov...

Scott Graybeal, CEO of Caelux, sits down to talk about perovskites-based nanotechnology that can improve the performance of silicon solar panels to produce 30% more power from the sun at a 10% lower cost than traditional panels. Caelux recently closed an additional $12 million in funding to build a manufacturing facility that will produce up to 100 MW of generation capacity. The $370 billion Inflation Reduction Act has reportedly been followed by between $213 and $511 billion in private investment, with hundreds of new solar, battery, and other cleantech facilities launched last year. It's a remarkable time to be in green technology because, as Scott explains, the U.S. has embraced an industrial vision and invested in making it happen for the first time since the Eisenhower Administration. Silicon-based solar panels have made tremendous progress since they came to public attention when the Carter Administration first installed them on the roof of the White House. The cost of electricity they generate has fallen by 99% as silicon solar panels achieved 20% efficiency. Perovskite, a calcium titanium oxide-based nanomaterial, can convert up to 30% of the sun's light into electricity, and recent research suggests they could become two-and-a-half times more efficient in the next few years.You can learn more about Caelux at https://caelux.com/

But can Gorin quietly replace hundreds of fire-breathing dragons without getting burned and starting a Second Dragon War? Maybe not...True Solar TakeawaysUnions are truly a part of our utility energy operations and construction. They bargain for good prevailing wages and benefits, and they can also get involved in energy politics. For example, utility unions largely oppose rooftop solar and will lobby for legislation and regulations that support large-scale solar (and their members). They also support legislation and regulations that disincentivizes rooftop solar. Why? Because small installation companies aren't part of the union and because they fear that rooftop solar will decrease utility solar jobs. In fact, we need both rooftop and utility solar in order to fight climate change.Likewise, coal, gas, and oil unions oppose solar because they also know that their jobs will decrease. But the clean energy writing is on the wall and their leadership understands that they will eventually need to support retraining their workers for clean energy and other industries.Energy wonks often refer to the cost of energy over time as the "Levelized Cost of Energy" or LCOE. It allows them to compare the total cost of a solar plant to, say, a gas or coal plant. Today, solar has the lowest LCOE. Milanium is an imaginary rare-earth metal. However, solar and clean energy is in great need of many rare-earth metals and not-so-are minerals. These include silicon, the base element for making solar cells for solar panels, and lithium for making rechargeable batteries. Peaker power plants are always on standby, so the cost to use them is very expensive. Utilities use speakers for backup power on hot days when more people are running their air conditioners.Solar technology is now mature and reliable. There are over 4 million solar installations in the U.S. and millions more around the world. PERC and TopCon are the current leading solar panel technologies. Perovskite solar panels haven't been commercialized yet, but they're close. Once commercialized, they will make solar panels less expensive and generate more power per square inch.Lithium-iron phosphate batteries are becoming more popular for home backup power.  However, most home batteries use Lithium-ion chemistries.The chemistry formulas for iron-air batteries are now being commercialized, allowing for affordable and long-lasting storage of solar and wind power.

SHOW NOTES 01:50 The first perovskite solar cell with a commercially viable lifetime is here | Interesting Engineering  A team of researchers from Princeton University has built the first perovskite solar cells that last long enough to be commercially viable.Silicon-based cells, which many regard as an expensive and suboptimal component, have dominated the renewable energy market since their introduction in 1954. This new technology, which is not only incredibly durable but also meets common efficiency standards, has the potential to change that. Expected to outperform industry norms for roughly 30 years, well beyond the 20-year criterion for solar cell viability Perovskite solar cells are regarded as high-efficiency, low-cost modular technology for implementation in the renewable power industry. Less Energy = Less $$$ Would become more fragile in that case The name “perovskite” comes from the nickname for their crystal structure. Can be manufactured at room temperature, which means they need less energy than manufacturing silicon.  Can be modified to be flexible and transparent The new device created by these researchers estimated lifetime is a five-fold increase over the previous record, which was established by a lower efficiency perovskite solar cell in 2017. Additionally they created a new testing method allowing them to test the longevity of these particular types of solar cells. Ranging from a regular summer day's baseline temperature to an extreme of 230 degrees Fahrenheit (110 degrees Celsius). “accelerated aging technique” Chose four aging temperatures and measured outcomes over four independent data streams. Overall, they found that the device will run at or above 80 percent of its peak efficiency under continuous illumination for at least five years.According to the researchers, that is the equivalent of 30 years of outdoor operation in a city like Princeton, New Jersey.  Joseph Berry, a senior fellow at the National Renewable Energy Laboratory who was not involved in the study, said:“This paper is likely going to be a prototype for anyone looking to analyze performance at the intersection of efficiency and stability … By producing a prototype to study stability, and showing what can be extrapolated [through accelerated testing], it's doing the work everyone wants to see before we start field testing at scale. It allows you to project in a way that's really impressive."   07:36 Immunotherapy booster produces 10,000 times more cancer-fighting cells | New Atlas Researchers at Washington University in St. Louis have found that adding a booster protein can significantly improve the outcome of cancer immunotherapy.The research showed the protein produced 10,000 times more immune cells in mice, and all mice survived the entire experiment. We are talking about  CAR T cell immunotherapy, which is a promising new treatment where doctors extract T cells from a patient, genetically engineer them to target specific cancer cells, and return them to the body to hunt those cells down.  The effectiveness can start to drop over time. In the new study, the scientists investigated ways to combat this problem by boosting the number of T cells. Doesn't naturally stick around very long, so the researchers modified it to circulate in the body for weeks. They turned to a protein called interleukin-7 (IL-7), which the body naturally expresses to ramp up T cell production in the event of illness. The team tested this longer-lasting IL-7 in mouse models of lymphoma, administering the protein on various days after the initial CAR T cell injection.3 groups: 1.) Control (no immunotherapy), 2.) Received CAR T cell therapy without IL-7, and 3.) with IL-7 John DiPersio, senior author of the study, talks on the findings:“When we give a long-acting type of IL-7 to tumor-bearing immunodeficient mice soon after CAR T cell treatment, we see a dramatic expansion of these CAR-T cells greater than ten-thousandfold compared to mice not receiving IL-7 … These CAR T cells also persist longer and show dramatically increased anti-tumor activity.” Every mouse that received CAR T cell therapy and IL-7 survived the entire 175 days of the experiment, with their tumors shrinking to the point of being undetectable by day 35. In contrast, mice that received immunotherapy alone survived just 30 days on average. Human clinical trials of IL-7-boosted CAR T cell therapy are set to begin soon in patients with a type of lymphoma.   12:29 Study identifies receptor that could alleviate need for chemo, radiation pre-T cell therapy | ScienceDaily   Before a patient can undergo T cell therapy designed to target cancerous tumors, the patient's entire immune system must be destroyed with chemotherapy or radiation.Reducing your immune cells helps the transferred T cells to be more effective.  Toxic Side Effects: nausea, extreme fatigue and hair loss. Now a research team ,a collaboration between scientists from UCLA, Stanford and the University of Pennsylvania, has shown that a synthetic IL-9 receptor allows those cancer-fighting T cells to do their work without the need for chemo or radiation. Christopher Garcia, PhD, at Stanford, talks on these T cells:“When T cells are signaling through the synthetic IL-9 receptor, they gain new functions that help them not only outcompete the existing immune system but also kill cancer cells more efficiently … I have a patient right now struggling through toxic chemotherapy just to wipe out his existing immune system so T cell therapy can have a fighting chance. But with this technology you might give T cell therapy without having to wipe out the immune system beforehand." Imagine being able to receive this treatment without destroying your whole body. The body would be in a much better position to fight off any other outside problem. Antoni Ribas, MD, PhD, a senior investigator on the study, believes this finding, “opens a door for us to be able to give T cells a lot like we give a blood transfusion." Back in 2018 a set of researchers found that a synthetic cell growth cytokine could be used to stimulate T cells engineered with a matching synthetic receptor. With this system, T cells can be manipulated even after they have been given to a patient. But they were looking at IL-2 back then, but now they started investigating IL-9. The synthetic IL-9 signal made T cells take on a unique mix of both stem-cell and killer-like qualities that made them more robust in fighting tumors. According to the researchers, "In one of our cancer models, we cured over half the mice that were treated with the synthetic IL-9 receptor T cells."Proved to be effective in multiple systems The process worked whether they gave the cytokine to the whole mouse or directly to the tumor   17:34 Astronomers Unveil The Most Detailed Map of The Metal Asteroid Psyche Yet | ScienceAlert  The asteroid Psyche is especially interesting, and NASA is sending a mission to investigate the unusual chunk of rock.In advance of that mission, a team of researchers combined observations of Psyche from an array of telescopes and constructed a map of the asteroid's surface. Psyche (16 Psyche) is an M-type asteroid, which is the rarest type of asteroid and makes up about 8 percent of known asteroids.Contain more metal than the other asteroid types, and scientists think they're the source of iron meteorites that fall to Earth. Called a dwarf planet because it's about 220 kilometers (140 mi) in diameter.  Psyche is sometimes called the 'Gold-mine asteroid' because of the wealth of iron and nickel it contains NASA wants to take a closer look at the asteroid.The mission is called Psyche and is scheduled for launch sometime in fall 2022.  The spacecraft will rely on solar-electric propulsion and a gravity-assist maneuver with Mars to arrive at Psyche in 2026. It'll spend 21 months studying the asteroid and will follow four separate orbital paths, each successive one closer than the previous. A team of researchers constructed a new map of Psyche's surface to help prepare for the mission.  Saverio Cambioni from MIT's Department of Earth said in a press release:“Psyche's surface is very heterogeneous … It's an evolved surface, and these maps confirm that metal-rich asteroids are interesting enigmatic worlds. It's another reason to look forward to the Psyche mission going to the asteroid." The new map is based on two types of measurements. Pure iron has an infinite dielectric constant.  One is thermal inertia, which is how long a material takes to reach the temperature of its environment. Higher thermal inertia means it takes longer. The second is the dielectric constant. The dielectric constant describes how well a material conducts heat, electricity, or sound. A material with a low dielectric constant conducts poorly and is a good insulator and vice versa. Combining thermal inertia and dielectric constant measurements gives a good idea of which surface regions on Psyche are rich in iron and other metals. Overall, the study shows that 16 Psyche's surface is covered in a large variety of materials. It also adds to other evidence showing that the asteroid is metal-rich, though the abundance of metals and silicates varies significantly in different regions.   22:39 World's most efficient passenger plane gets hydrogen powertrain | New Atlas  The Celera 500L is a remarkable design, and according to the company behind it, Otto Aviation, its odd shape delivers an astonishing 59 percent reduction in drag, and a massive leap in efficiency and range compared to traditional plane geometries. Otto claims the Celera 500L in standard fossil fuel-propelled form is "the most fuel-efficient, commercially viable business aircraft in the world."The whole thing is designed to maximize laminar flow – smooth layers of airflow with little to no mixing of adjacent layers moving at different speeds. Trying to avoid the swirls and eddies that lead to air turbulence at speed, causing aerodynamic drag and wasted energy. The company states that it uses 80 percent less fuel than a traditional design. Running on an efficient 550-horsepower combustion engine, Otto claims this thing will fly six passengers up to 4,500 nautical miles (8,334 km) at cruise speeds over 460 mph (740 km/h), challenging small business jets for top speed while more than doubling their range.A glide ratio of 22:1 allows pilots to switch off the engine altogether and glide for up to 120 miles (200 km) completely unpowered. Now the rich people who fly around in their CO2 producing private jets can make a change…will they? Otto has built a full-scale prototype, and by November last year the company announced it had completed some 55 successful test flights, reaching speeds over 250 mph (400 km/h) and altitudes up to 15,000 ft, and that "all test flights have validated the aircraft's operating performance goals." Otto has now announced a collaboration with hydrogen aviation pioneers ZeroAvia to develop a fuel cell-electric powertrain specific to the Celera's requirements.The shape works well with a hydrogen concept – hydrogen powertrains can weigh much less than battery-electric ones, but they tend to take up a bit of space. ZeroAvia is being relatively humble with its ambitions to begin with, aiming for a range of just 1,000 nautical miles (1,852 km) of zero-emissions range for a hydrogen-fueled Celera. Founder and CEO of ZeroAvia, Val Miftakhov, said in a press release:“The majority of our commercial deals to date have focused on retrofit and line-fit for existing airframes, which is essential to deliver zero-emission flight to market as quickly as possible. However, efficiency gains from new airframe design can expand the impact of zero-emission aviation. We are pleased to collaborate with innovators, like Otto Aviation, bringing cutting-edge clean sheet designs to market as we can optimize the hydrogen-electric propulsion system for those designs.” Otto has already shown it can complete successful flights of their fossil fuel plane, but we will wait and see how this partnership pans out.

È sempre difficile valutare l'impatto di una nuova ricerca, ma i risultati ottenuti dai ricercatori del California NanoSystems Institute, pubblicati su nature Nature di Marzo, rappresentano senz'altro una tappa importante nello sviluppo della più studiata e ricercata tra le alternative al fotovoltaico al silicio: il fotovoltaico alla perovskite.Il fotovoltaico alla perovskite è al centro delle ricerche di scienziati di mezzo mondo perché promette l'abbattimento dei costi e una grande semplificazione del processo di produzione. A differenza del silicio, infatti, le perovrskiti possono essere depositate sotto forma di sottilissimi film a partire da soluzioni liquide non tanto diverse da inchiostri. Celle di questo tipo vengono prodotte con facilità nei laboratori di mezzo mondo, ma c'è un problema: si degradano rapidamente finendo per diventare inutili nell'arco di mesi, e nessuno finora era riuscito a risolverlo.Finora, perché si direbbe che finalmente, questa volta, ci siamo.

Em apenas dez anos de pesquisa, as células solares de perovskitas tornaram-se competitivas em termos de eficiência. Atualmente, sabe-se que a sua capacidade de converter luz em eletricidade é maior ainda quando elas são empilhadas em cima de células solares de silício, formando uma junção de dispositivos chamada “tandem”. Contudo, esses bons resultados correspondem geralmente a dispositivos pequenos, usados para pesquisa em laboratório. Conseguir produzir grandes áreas de perovskitas sem prejudicar a eficiência ainda é um desafio. A perovskita propriamente dita é um óxido de cálcio e titânio3. Foi descoberta nos montes Urais, na Rússia, em 1839. E recebeu esse nome em homenagem ao mineralogista russo Lev Perovski (1792-1856), ministro do Czar Nicolau I. Para se obter perovskitas pelo método de gas quenching, o primeiro passo consiste em depositar, sobre um suporte, uma solução contendo os compostos precursores da perovskita. Quando o solvente evapora, o material cristaliza e forma a organizada estrutura própria das perovskitas. Na preparação das soluções iniciais, a equipe de pesquisadores utilizou dois solventes diferentes combinados com diversos precursores e observou que cada combinação leva a um caminho único de formação de intermediários, o que impacta na morfologia e nas propriedades finais da perovskita, bem como na sua eficiência dentro das células solares. Study paves the way for the development of more efficient solar cells. In just ten years of research, perovskite solar cells have become competitive in terms of efficiency. Currently, it is known that their ability to convert light into electricity is even greater when they are stacked on top of silicon solar cells, forming a junction of devices called “tandem”. However, these good results generally correspond to small devices, used for laboratory research. Managing to produce large areas of perovskite without impairing efficiency is still a challenge. Perovskite itself is a calcium and titanium oxide3. It was discovered in the Ural Mountains in Russia in 1839. It was named after the Russian mineralogist Lev Perovski (1792-1856), Minister of Czar Nicholas I. To obtain perovskites by the gas quenching method, the first step is to deposit, on a support, a solution containing the precursor compounds of perovskite. When the solvent evaporates, the material crystallizes and forms the organized perovskite structure. However, before this happens, several compounds with different structures (so-called “intermediates”) are formed momentarily. In the preparation of the initial solutions, the research team used two different solvents combined with different precursors and observed that each combination leads to a unique path of formation of intermediates, which impacts on the morphology and final properties of perovskite, as well as on its efficiency inside the solar cells. In addition to providing valuable information on the formation of perovskites by gas quenching, the results of the research help in choosing the best solvent to obtain better perovskite films for solar cells, including those of the tandem type.

It will delight the added value materials suppliers and horrify the traditional electronics and electrical engineering industries where they are bypassed. The trend is seen in 2.2 GW of thin film solar being installed in 2020 because this copper indium gallium diselenide is flexible and light-weight for building facades etc. Renovagen will even sell you 300kW reels to unroll like a carpet and use as a microgrid. Electrics and electronics become added-value materials. Research groups have demonstrated batteries, sensors and triboelectric harvesting you cut to shape and they still work. Customizable, fabric-like power sources can be cut, folded or stretched without losing function. Perovskite and quantum dot photovoltaics show promise for photovoltaic paint. In many cases, the new technologies are not just edit-able, they replace other functions from load-bearing parts to regular paint and building cladding - two or three for the price, space, weight of one. That can justify high margins. Industrial supply chains are being bypassed, parts are being eliminated and value-added material companies see huge opportunities ahead for this electrically-smart feedstock, reels and paint. Where they sell electrical ink to the start of traditional production lines, they will sell cleverer versions direct to many other industries.For more information on this report, please visit www.IDTechEx.com/ElectronicsReshaped or for the full portfolio of research available from IDTechEx please visit www.IDTechEx.com/Research.

Solar energy is the ideal way to power a spacecraft. There's no weather, there's no pesky atmosphere, just pure photons streaming from the Sun to harvest for whatever you need. Well, as long as you're within the inner Solar System. But solar panels are complicated and fragile made of sensitive electronics and glass - not to mention, really heavy. Any spacecraft equipped with solar panels needs to handle the gravity down here on Earth for the construction and testing, then the shaking and high Gs of launch. The solar panels need to unfold perfectly once they get to space. And the total amount of energy you can harvest is limited by the size of your rocket's launch fairing. Maybe there's a new strategy. NASA is currently funding research into a new type of solar panel that can be carried into space as a liquid and then sprayed onto a surface to turn it into a power generating surface.

(B-Side: Being for the Benefit of Mr. Perovskite!)Can we produce solar cells efficient enough to make a real dent in our fossil fuel consumption? In this episode, Jocelyn and Bradley talk with Dr. Andrew Yost, Assistant Professor of Physics at Oklahoma State University, whose research addresses this question. With some judicious cursing, Andrew describes the advantages and disadvantages of various solar cell materials, including traditional silicon-based approaches, a special class of materials called perovskites, and the new promise of quantum dots. He even tells us how we can print our own flexible solar cells at home using a regular inkjet printer! As the friends discuss the “hope and hype” of solar energy, myths about solar cell efficiency, and how science communication will play an essential role in transitioning the U.S. from a fossil fuel society to a renewable energy one, we also learn about Andrew’s journey into science and the most challenging and gratifying aspects of his life and work.

Research on perovskites has progressed rapidly for PV and LEDs, with new solar-cell efficiency records being set at a regular pace. There are hints of the first commercial products reaching the market by 2020, just a decade since perovskite photovoltaics were first discovered. MRS Bulletin presents the impact of a recent advance in this burgeoning field. Read the abstract in Science (doi:10.1126/science.aau5701).TranscriptWelcome to MRS Bulletin’s Materials News Podcast, providing breakthrough news & interviews with researchers on the hot topics of 3D bioprinting, artificial intelligence and machine learning, bioelectronics, perovskites, quantum materials, robotics, and synthetic biology. My name is Bob Braughler. Metal-halide perovskite solar cells degrade when exposed to oxygen and moisture. Encapsulating the devices makes them more stable and long-lasting, but it does not solve one issue that crops up during regular device operation. Light, electric field, and thermal stress can all make lead and iodide ions more reactive, generating lead and iodine defects that serve as recombination centers for charge carriers and bring down device efficiency and lifetime. Researchers at Peking University have invented a novel technique for combating these defects. They added a rare-earth europium ion pair to lead-iodide perovskites. The redox pair shuttled electrons in a cyclical fashion from the defects, oxidizing lead and reducing iodine to recover lead and iodine ions. Devices with this redox shuttle have a power efficiency of 21.52%, and they retained more than 90% of this efficiency under 1-sun continuous illumination or heating at 85°C for 1500 hours. This work was published in a recent issue of Science. My name is Bob Braughler from the Materials Research Society.

My name is Bob Braughler. The presence of lead in state-of-the-art perovskite solar cells could hold back their commercialization. Lead-free alternatives based on tin compounds have shown promise, but they typically suffer from low efficiency and stability.Brown University’s Yuanyuan Zhou and Nitin Padture and their colleagues have made a surprising discovery that provides a solution. They found that simply adding germanium to the lead-free perovskite cesium tin iodide, which degrades easily, makes it air-tolerant. Devices made with the new perovskite show an efficiency of 7.11% and remain highly stable after 500 hours of operation under 1-sun illumination. The key to this behavior is the extremely high oxidation activity of germanium, which forms an ultrathin, uniform oxide layer on the surface, which—as the researchers write—“fully encapsulates and passivates the perovskite surfaces.” This work was published in a recent issue of Nature Communications.

My name is Bob Braughler. Concentrated photovoltaic devices – also called CPV, which use lenses and mirrors to focus sunlight onto small, highly efficient solar cells, can have power-conversion efficiencies as high as 46%. Very expensive multi-junction solar cells made with groups III-V semiconductors, such as gallium indium phosphide, are often used for such devices.Could perovskite solar cells, which suffer from instability under light and heat, be used for CPV technology? University of Oxford researchers led by Henry Snaith answer that question. They found that the efficiency of halide perovskite solar cells went up from 21.1% to a peak of 23.6% when simulated sunlight was increased to 14 times the standard irradiance of 1 Sun.The researchers assessed a range of perovskite materials for their stability under high-intensity light. Perovskites containing a mixed cation formamidinium-cesium composition gave the most stable solar cells under high irradiance, and they chose a compound with a composition of formamidinium, cesium, lead iodide, and bromide for the CPV device. They found that their devices, maintained at room temperature during operation, retained 90% of their original efficiency after 150 hours spent under 10 Suns of concentrated light.This work was published in a recent issue of Nature Energy.

2016 12 31   This the World Organic News yearly roundup episode. And what a year its been! I’ve identified four broad themes to 2016. Let’s get into them   Firstly, Cities. Perhaps the most unlikely place to find farming but here it is. Rooftop, vertical, empty lot and balcony/terrace farming/gardening as well as the suburban homesteader all featured this year in the blog and on the podcast.   Small areas, intensively planted and thoughtfully custodianed can produce huge amounts of food. That people are doing this is a sign of our longing for real food. That people are doing it in cities is a sign the long, fossil fueled based, supply lines may not be as safe as we are led to believe. It is also a sign people are looking for flavour. An heirloom variety of tomatoes that grows well in container on a balcony will never be capable of bulk transportation across 1000s of kilometres. It will however have flavour to balance its inability to travel.   On a more industrial scale, the Japanese plan to open a fully automated vertical farm harvesting, initially, 1000s of lettuce a day before diversifying into other leafy vegetables. As I’ve stated elsewhere, peopleless farming doesn’t sit right with me but it is an option during famines, disaster relief and so on when the need to feed people is greater than the need for human interactions with food. I just realised that argument can be extended to feeding people at anytime yet peopleless farming still doesn’t sit right with me.   The urban/suburban homesteading movement continues apace as more individuals and families see the benefits of growing their own. The homesteading side of this movement usually involves some sort of animals to add to the mix. This allows manure collection and increased soil health and productivity. I’ve seen people growing rabbits on this scale but the usual and animal is the chicken! The good thing about chooks is they will give you manure and an egg a day whether you have a rooster or not. With a rooster comes the joys of breeding but in some council areas roosters also bring noise complaints. And remember kids, chickens are the gateway stock to larger animals! It is a very small step from hens to backyard goat!   The second theme for 2016 is biotech! This year has seen Washington State sue Monsanto for residues in the environment and the Australian High Court reject an appeal from Steve Marsh against a contamination of his land by a neighbour’s GMO canola pollen. Mixed messages! Burkina Faso has dumped BT Cotton and returned to standard types. Still chemically grown but a step in the right direction. To add to this small step against Monsanto, the World Health Organization declared Monsanto’s flagship pesticide Roundup a probable carcinogen. Probable is one step down from carcinogenic. The reason why Roundup only received a probable rating is a lack of evidence. The WHO will continue to collect data and review its rating of Roundup as it does for all the declared probable carcinogens.   Perhaps more troubling is merger between Bayer and Monsanto. Two enormous biotech, chemical and seed producers merging into a huge corporation. Could they use this market power for good or does that word not enter into the economic considerations? The point of corporations is simply profit. Sad but true. Individuals in positions of power within corporations may consider things other than profit but people come and people go. The corporation or one very much like it will continue to live for nothing but profit. So it augers not well for the biosphere from this merger. We will have more to say on this in 2017, I’m sure.   As many of us have noted and the BBC statistical radio show “More or Less” proved, 2016 was a year of high profile deaths. The one which impacted the organic movement most strongly was, off course, the passing of Bill Mollison. Bill’s passing marked the loss of the last of the triumvirate who influenced my path into and through the organic movement. The other two being John Seymour and Masanobu Fukuoka. So a particularly deep loss not just me but for many. What can I say that has not already been said? This world is a lesser place without Bill. Yet his work lives on. I have yet to find a country, even war torn one, without permaculture. The genius of Mollison’s and Holmgren’s work is the universality of the method. Across climate zones from Desert to Jungle Permaculture both has a place and is being implemented as I speak. Truly a legacy we will only truly understand with passing of time.   Despite or, if you are of that persuasion, because of, the political changes in 2016,  World Organic News still believes there is room for hope in this world. We have the tools to feed the world. Feed the world healthy food which not only does not damage the biosphere but actually heals it. We have a rising number of young farmers across the developed world for the first time in generations and they are overwhelming organic practitioners. Do we see the start of a truly grassroots movement? World Organic News hopes so.   On another positive note, the positive outcomes from Paris COP20 in 2015 to Morocco COP21 there is a path forward on climate change. Even if we weren’t facing the challenges of climate change, a move to fossil fuel free economies would still make sense. The pollution from the fossil fuel industry will take centuries to remediate and that time is continuously being pushed back as we cling to this dirty fuel.   Perovskite solar cells continue to set new efficiency records, silicon solar cells are now the cheapest form of energy production. Despite the politically based claims against climate change one thing and one thing alone will drive both believers and skeptics and that is price. As economies of scale continue to kick in this price difference will only increase. Once this gains momentum the subsidies paid to fossil fuel producers will come under increasingly strong pressure. The question before us is one of timing. Can we make the transition in time?   There is also something we can all do. The organisation Kiss the Ground (https://www.kisstheground.com/) has a great series of videos explaining how, since about World War Two, carbon has been liberated from the soil and dispersed to the atmosphere. More importantly the videos explain how to move the carbon back to the soil.   And this is what organic methods can and will do! Surely this is hope enough to take us into 2017 with heads held high, ready to face the effects of our species’ actions and to do something about it!   I’ll be back on the 9th of January 2017 with a return to the weekly roundup of news, ideas and methods from the Organic World!   I am contractually required to mention that I have new microphone and hopefully the sound quality has improved. Let me know if you think it has improved.   If you’ve liked what you heard, please tell everyone you know any way you can! I’d also really appreciate a review on iTunes. This helps others to find us. Thanks in advance!   Any suggestions, feedback or criticisms of the podcast or blog are most welcome. email me at podcast@worldorganicnews.com.   Thank you for listening and I'll be back in a week.

Jon Moore reporting! This week we begin with news from the academy! Those curiously named solar cells perovskites have hit new efficiency levels. The blog: Great Things from Small Things .. Nanotechnology Innovation brings us the post: Perovskite solar cells hit new world efficiency record. Quote: They’re flexible, cheap to produce and simple to make – which is why perovskites are the hottest new material in solar cell design. And now, engineers at Australia’s University of New South Wales in Sydney have smashed the trendy new compound’s world efficiency record. End Quote. This is wonderful news. Non fossil fuel based energy is the way forward. After generations of research focused on fossil fuels, bright minds are now and have been for a while driving alternatives. Perovskites are quick and cheap to manufacture, increasingly efficient but do suffer from some stability issues in open weather. There are workarounds to overcome these issues. The increasing efficiencies may make these drawbacks irrelevant. The research continues and with it hope for the future. Even using “standard” PV cells it is possible to make great advances. The blog Antinuclear brings us a post entitled: Australia can get to zero emissions, as rooftop solar booms. Funnily enough if the price signals are sufficiently strong and the technology serviceable, individuals will make decisions which collectively benefit us all. This is what’s happened in Australia with rooftop solar cells. To such an extent, the CSIRO can see them as Australia’s pathway to zero emissions. Quote: Consumers using rooftop solar panels and batteries will produce between a third and half of Australia’s electricity by mid-century if the right policies are introduced, according to a roadmap from the CSIRO and power and gas transmission body Energy Networks Australia. The two-year analysis also found an emissions intensity scheme for the electricity sector – a form of carbon trading that was to be considered by a government climate policy review until that plan was abandoned on Tuesday afternoon – would be the cheapest way to cut carbon dioxide emissions. End Quote. The report suggested the entire electrical grid could be zero carbon emitting when rooftop solar is coupled with batteries by 2050. Whilst this doesn’t deal with road transport and other emitters of CO2, the grid is a great place to start. Now we move onto another great news story. Suzanne's Mom's Blog brings us the post: Detroit’s Sustainable “Agrihood”. Given the economic disasters which have befallen Detroit in the past thirty years, this post is one of great promise. As vast swathes of greater Detroit have been abandoned following the crisis of 2008, land has become available for alternative use. To be specific for food production. From the blog post: Quote: “This week, the Michigan Urban Farming Initiative (MUFI) revealed its plans for the first Sustainable Urban Agrihood in the North End. “Wait, an agrihood? It’s an alternative neighborhood growth model, positioning agriculture as the centerpiece of a mixed-use development. There are some agrihoods around the country, but in rural areas. This is the first within a city. End Quote. From the great pains of economic downturn comes the possibility of a better way to live. Food grown where it is consumed, employment, renewal and a future. I recommend a reading of the whole post. It is uplifting. How soil is lost is a post from the blog Make Wealth History. I think we’ve made the point in earlier episodes that without soil, we are in dire straights. This post reminds us of how precious this resource is and how we are losing it. Quote: ....soil is a self-maintaining system. In nature, it looks after itself. When humans intervene with agriculture, the balance can be lost and the processes interrupted. Soil works in tandem with the vegetation that grows from it, as a mutually reinforcing dynamic. Plants need soil, and soil needs plants.  Unfortunately, we tend to clear the land completely in order to choose what grows from it, breaking that cycle. Then we haul away what’s been grown, keeping the grain as food and baling up the stalks, rather than letting the soil re-absorb the nutrients. The result is a gradual loss of fertility, and we have to make up the difference with chemical fertilisers. End Quote. Given the long history of agriculture and its increased pace with population growth, we could be in for trouble. So far extreme soil losses have been relatively confined to nation states. Think The US Dust Bowl of the Great Depression and the dust storms from northern China covering Beijing with topsoil in the late 1990s. The post though provides some sobering statistics: Quote: Globally, the equivalent of 10 million hectares of arable land is lost every year. In the last 150 years, we have lost half the world’s topsoil.  When land is exhausted, farmers move on and start somewhere else. The FAO estimates that 20 million hectares of farmland is abandoned every year. End Quote. The good news is we can reverse this. Permaculture, Natural Farming, Agroforestry and Biodynamic methods to name but a few options we already know work and are productive and sustainable. Remember the US Dust Bowl was reversed through good soil retention techniques. We can reverse, indeed, we must reverse this trend whilst we can.       And that brings us to the end of this week’s podcast.

Perovskite solar cells are widely touted to be the next generation in solar technology.

Today’s carbon-based economy will not be sustainable in the future. Not only will the known reserves of fossil fuels, like oil, natural gas or coal, be significantly reduced within the next 100 years, but the continued burning of fossil fuels also emits greenhouse gases, which have led to a global increase in temperature, called global warming. To preserve the environment for future generations and to prepare for the time when we will inevitably run out of fossil fuel, we have to change the way we produce our primary energy and focus research and investments on renewable energy sources. While energy from wind and water is already harvested with very high efficiencies, the utilization of solar energy still offers big room for improvements. Although conventional crystalline silicon cells achieve efficiencies around 25 %, their production is very energy intensive and relies on advanced production technologies, which makes them still rather expensive. To make photovoltaics a major part of our energy landscape, an easily prepared type of solar cell consisting of cheap and abundant materials is required. Novel organometal halide perovskite-type materials fulfill these requirements and have proven to be serious competitors for conventional photovoltaics. After only four years of research they already achieve power conversion efficiencies above 20 %. This thesis introduces a fast and easy way to prepare planar heterojunction solar cells based on methylammonium lead iodide (MAPbI3). The photoactive layer is deposited in a 2-step deposition approach, where a thin film of the lead precursor is converted into the final perovskite simply by immersing it into a solution of the other component. The resulting films consist of individual crystals sizes a few 100 nm and covering the whole substrate without significant gaps or holes. Solar cells prepared by this method achieve power conversion efficiencies of 15 %. Furthermore, by adjusting the temperature of the immersion bath, the orientation of the perovskite crystals can be controlled. The orientation, together with the resulting change in efficiency and resistance, gives interesting insights into the anisotropic charge transport properties of this class of materials. Additionally, the conventionally used hole blocking layer, titanium dioxide, was replaced by one made of fullerene molecules. The efficiencies achieved by solar cells employing this kind of electron selective contact reached almost 10 %, although the reproducibility was initially very low. This was attributed to a partial dissolution of the fullerene film during the subsequent preparation steps. To increase the stability of the layer, it was photo-polymerized using UV radiation. This not only reduces the solubility and therefore increases the fraction of solar cells achieving high efficiencies; it also changed the energy levels close to the bandgap. The bandgap energy of organic lead halide perovskite materials is strongly dependent on the composition. By exchanging some or all of the iodide in MAPbI3 with bromide, the difference between valence and conduction band can be changed from 1.5 eV (pure iodide) to 2.25 eV (pure bromide). This substitution can be performed gradually, so that phase pure materials with properties in between the two extremes are obtained. The pure bromide MAPbBr3 perovskite, however, does not perform efficiently in a planar heterojunction solar cell. Its close relative based on formamidinium FAPbBr3 has also been investigated for its suitability as active solar cell material. Although it is structurally very similar to MAPbBr3, with equivalent light absorption and emission properties, a 10 fold higher efficiency was observed for the FA-based compound. This striking difference is mainly attributed to an increased photoluminescence lifetime, resulting in an increased diffusion length of the free charge carriers. Apart from their application as light absorbing materials in solar cells, perovskites have also been investigated for their application as light emitters. Depending on the perovskite used, it was possible to demonstrate red light emission (MAPbI3) or green emission (MAPbBr3).

Hydrogen is regarded as an excellent candidate future fuel on the grounds that it is relatively easy to store and it burns cleanly to produce only heat and water. But present methods of production involve fossil fuels and are energy intensive, offsetting any benefits of the hydrogen. Instead, scientists would like to use electricity from renewable sources to split water into hydrogen and oxygen, with solar power being one obvious choice.
