Spain's utility Iberdrola is upgrading its pre-existing hydropower reservoirs to pumped hydro - a huge potential storage reservoir for Western Europe. The UK has announced it will expedite offshore wind permitting times, potentially halving lead times in the world's second-largest market for such projectsSome perovskite solar manufacturers have raised the funding they need to fund mass production and commercialisation - but many others haven't yet, in the context of economic uncertainty and a looming recession.

China will switch its renewable energy power projects over to market-based pricing from June 1st 2025, while also abolishing battery co-location requirements, following on from ever steeper time-of-day pricing, and a 2024 reform which introduced capacity payments for coal and gas plants. China's reform parallel the more gradual reforms cutting Feed-in tariffs and Net Metering across multiple Western markets. The Trump Administration intends to boost domestic oil and gas production and exports - this is bad news for renewable energy investments worldwide, as would a loosening of sanctions on Russia, but transmission is the main limiting factor in many mature markets anyway. Compressed-air energy storage (CAES) is being built out in artificial excavations in China at prices which aren't wholly worse than lithium-ion BESS, considering the relative youth of the technology. Perovskites and solid-state batteries face the same problem - the mainstream technologies of silicon PV and LFP batteries are already cheap and high quality, and are also still improving their quality, preventing a 'moving target' to the more innovative future replacement.

Perovskites are crystal structures that can be manufactured in labs for making solar panels.  They are relatively cost-effective, and efficient, and could provide a reliable thin-film alternative to the more common silicon-based solar panels.  However, perovskite solar cells face a few challenges that must be addressed before they can become a competitive commercial PV technology. In some forms they can be unstable, and lead can be a toxic byproduct when processing them. And yet, perovskite-based materials also could have green energy potential beyond solar as batteries and alternatives to modern refrigerants that use chlorofluorocarbons (CFCs), which are strong greenhouse gases.That's why Jyorthana Muralidhar is fascinated by perovskites. She is a Wilkes Center-funded postdoctoral researcher working in Professor Connor Bischak's Lab, in the Department of Chemistry at the University of Utah. There she spends her time manipulating 3-dimensional, 2-dimensional, and 1-dimensional perovskite crystals into various combinations and shapes – all with the hope of discovering a new combination that could become the next clean energy breakthrough.   Recently, Jyorthana had some time to talk about her research.  

In this podcast episode, MRS Bulletin's Laura Leay interviews David Cahen from the Weizmann Institute of Science, Israel, about the impact surface defects have on bulk properties, specifically in the case of lead halide perovskites. In a perspective he co-authored, Cahen connected numerous experimental data from other researchers that exposed this phenomenon. By understanding how surface defects control the material's electronic behavior, researchers can pursue new materials for the development of long-lasting devices. This work was published in a recent issue of Advanced Materials. 

https://youtu.be/gbRn1j39M0EMatt had the chance to chat with Dr. Chris Case, CTO of Oxford PV, about the future of solar energy and their breakthrough perovskite tandem cells.

China's perovskite sector keeps announcing new factories - but what's needed to produce a Minimum Viable Product solar panel using the new semiconductor? Germany's 215 GW solar target for 2030 implies up to $100 billion investment also needed in energy storage batteries on the grid. Policy contrast widens on Chinese EV import tariffs between US exclusion, Australian free trade, and EU indecision.

In this podcast episode, MRS Bulletin's Sophia Chen interviews Yen-Hung Lin of Hong Kong University of Science and Technology about his work to eliminate defects in perovskite solar cells. Lin's group treated the perovskites with a category of molecules known as amino-silanes, which bind vacancies in the perovskites, preventing recombination of the electrons and holes. The amino-silane treatment retained the device's performance at 95% power conversion efficiency for more than 1500 hours. This work was published in a recent issue of Science. 

In this episode, our hosts discuss:1.

In this episode the Rethink Energy team discusses: The latest SNEC Exhibition in Shanghai, the biggest conference in the solar industry, shows that technological upgrading continues, with some silicon PV modules over 25%, and the first perovskites brought to market by Microquanta and Utmolight in the BIPV sector. Norway's hydropower fleet is getting gradually outscaled by rising electricity demand - prompting the country to join the ranks of Nordic governments considering a nuclear-powered energy strategy.

Neil Spann, CEO of Power Roll, joins us to discuss the British startup's microgroove technology. The main development angle which the company is pursuing for these microgrooves is a unique photovoltaic cell-module architecture which can be used for thin-film solar - for now, that means perovskites. We discuss the state of the solar market, of the Building-Integrated photovoltaic (BIPV) sector, of perovskite adoption in general - and the specifics of Power Roll's technology and its plans for manufacturing scaleup and commercialization.

In this podcast episode, MRS Bulletin's Laura Leay interviews Aram Amassian from North Carolina State University about his group's achievements using RoboMapper, a materials acceleration platform. In researchers' quest to run environmentally-conscious laboratories, Amassian offers a solution that focuses on characterization of materials. Having found that characterization generates a lot of energy, his group developed an automated approach to screening small samples in order to identify ones that warranted more in-depth study. By using their automated approach, the researchers found quantitative structure–property relationships for wide-bandgap perovskites. This work was published in a recent issue of Matter.

Perovskites are cheap, abundant photovoltaic materials that some have hailed as the future of green energy.Around the world, companies are layering perovskites on top of traditional silicon to develop so-called tandem solar cells that some think could deliver at least 20% more power than a silicon cell alone.However, there remain multiple issues to overcome before these products are ready for widespread uptake in the notoriously competitive solar-power market.This is an audio version of our Feature A new kind of solar cell is coming: is it the future of green energy?

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/

Saudi Arabia and the United States are exploring a partnership which would see Saudi money invested in African mining assets, guaranteeing US customers a cut of production. Power Roll explains its microgroove perovskite technology which sees it produce adherable sheets which see kilowatts of panels transportable under the arms of installers. Vale has announced that it will be investing $25-$30 billion in assets focused around Indonesia, Brazil, and Canada as it looks to expand its nickel and copper output.

In the year since the Inflation Reduction Act supercharged clean energy manufacturing, rarely does a week go by without a new solar factory notice. Rich incentives have led to unprecedented investments.But making solar panels is really hard. Not only does it require a lot of energy, but complicated global supply chains leave profit margins razor thin. And existing technology is bumping up against theoretical efficiency limits.Industry heavyweights see perovskite solar cells as the heir apparent to the crystalline chemistries that currently dominate global supply. They're betting that perovskites will offer a domestically produced, higher-efficiency, flexible, and cheaper alternative.The perovskite revolution is not without its detractors, though. Sizeable achievements are needed to take perovskites from labs to commercial viability.Episode 57 of the Factor This! podcast features Joseph Berry, a Senior Research Fellow at the National Renewable Energy Laboratory, and Paul Warley, the CEO of Ascent, a company working to commercialize perovskites for agriculture and space applications.Perovskites could be the missing link as terawatt-scale solar and broad decarbonization are pursued. Or, they could end up on the proverbial ash heap of history. Which is it?The Factor This! podcast is growing!

Yet their potential is huge; they represent the next generation of materials to harness the relationship between energy and light.Like perovskites, the scientific landscape in Mexico is also a bit ambiguous. The lack of history and of an established scientific infrastructure make it hard to do research in the country. However, a there are promising, yet still isolated, success stories and spring of new talent, such as Diego Solis-Ibarra, that suggest a new dawn for Mexican science. The conversation with Diego is an amazing story of a brave and talented young man, with a deep connection to his roots and the determination to embrace challenges not many would even consider. He traded a relatively easy scientific career abroad for being the steward of the growing scientific culture in Mexico. His research is as punchy and disruptive as his personality. We learn about the amazing technology of perovskites, while discovering a great scientist's profile.

This week's guest is Joel Jean, Co-Founder & CEO of Swift Solar.Before joining Swift, Joel served as Executive Director of the Tata-MIT GridEdge Solar research program, which focuses on scale-up of new solar photovoltaic technologies for India and other developing countries. He developed ultra-lightweight, flexible solar cells that the 2017 Katerva Award recognized, and he was named a Forbes 30 Under 30 Fellow in Energy.Swift Solar is designing and manufacturing lightweight solar panels and cheaper, more efficient systems than existing products. The company is working on a new kind of technology called Perovskites. Perovskite uses a crystal structure that allows you to tune the material. Swift Solar is tuning Perovskite panels to absorb different parts of the solar spectrum. The team stacks two Perovskites on top of each other; the top panel absorbs blue and high-energy light, while the bottom panel absorbs red and near-infrared light. Swift Solar's goal is to optimize different parts of the solar spectrum to make a more efficient solar cell. The company was founded in 2017 by leading perovskite scientists from Stanford, MIT, Cambridge, Oxford, and the National Renewable Energy Laboratory.In this episode, Joel explains how the Perovskite technology works and where it fits in the renewable energy and solar landscapes. We deep dive into Swift Solar's incorporation, the research behind the technology, and the company's progress to date. Joel also touches on funding in the solar energy space, why LPs are hesitant to invest in it, and how the sector has evolved since the early 2000s. Joel is a great guest with a wealth of knowledge on solar and Perovskite technology. This is a fantastic episode for those looking to double click on new solar technologies.Enjoy the show!You can find me on twitter @jjacobs22 or @mcjpod and email at info@myclimatejourney.co, where I encourage you to share your feedback on episodes and suggestions for future topics or guests.Episode recorded February 12th, 2021To learn more about Swift Solar, visit: https://www.swiftsolar.com/To learn more about this episode, visit our website: https://myclimatejourney.co/ctss-episodes/swift-solar

In this episode the Rethink Energy team discusses our recently released report on perovskites, a novel type of solar photovoltaic while will gain a significant chunk of market share by 2030: Ford's overstated commitment to EVs; and how the major forecasters such as Bloomberg and Wood Mackenzie continue to underestimate the impact that green hydrogen and EVs will have on oil through to 2050.

Many of us think of the US government’s role in solar innovation in terms of laboratories, deep science, and long term projects.  But, that is only part of the story. Listen in as Dr. Becca Jones-Albertus, Director of the Solar Energy Technologies Office in the US Department of Energy, shares how her office’s programs are bringing innovation to market more quickly than ever before and creating greater access for all Americans to clean renewable solar energy.

A new kind of solar cell - made by drying a special liquid on a surface - is being heralded as a revolution in solar power. The minerals known as perovskites were discovered more than 150 years ago. More recently, their crystal structure has been copied using other materials and used to produce energy. If it can be made to work, these crystals could be used to literally print out solar cells to put on skyscraper walls, furniture and electrical gadgets.

What IS Perovskite and why have we never heard of it before?  Chris Case, CTO of Oxford PV looks at the huge potential...and limitations of this synthesized material which is hundreds of times more efficient at absorbing sunlight than existing silicon technology.

Researchers at the University of North Carolina at Chapel Hill stabilize solar cells by converting the surfaces of lead halide perovskites to water-insoluble lead oxysalt, as reported in Science. Researchers at Weizmann Institute of Science open a new path to defect management in materials by providing insight into the low defect density of halide perovskites, as reported in Materials Horizon. Researchers at the University of Oxford add ionic liquids to perovskites which markedly improves the devices’ long-term stability, as reported in Nature. Researchers at Kyushu University make exceptionally thick organic light-emitting diodes by combining thin organic light-emitting films with hybrid perovskite charge-transport layers, as reported in Nature.

(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.

My name is Bob Braughler. While lead-halide perovskites have revolutionized photovoltaics, they have also shown promise for lasers, light-emitting diodes, and transistors. Now, researchers show that perovskite nanocrystals are also highly effective catalysts for organic synthesis. Reactions that form carbon–carbon bonds are the basis of synthesizing drugs, plastics, and chemicals. But the reaction procedures are complicated and require expensive noble metal catalysts. A research team led by Yong Yan at San Diego State University found that colloids of methylammonium lead tribromide and cesium lead tribromide are 1000 times as effective as iridium- and ruthenium-based catalysts for catalyzing the α-alkylation of aldehydes, a valuable and widely used chemical reaction. The perovskites cost approximately 100 times less. For the simple one-pot reaction, the researchers mixed organic starting materials into a suspension of the perovskite nanocrystals. Blue-light illumination triggers reactions that generate several products. By tweaking the reaction condition, the researchers can selectively catalyze other important chemical reactions.

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.

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. Researchers have made an all-perovskite tandem solar cell with a record high power-conversion efficiency of 21%.Tandem solar cells are more efficient than a single cell because each device in the stack can be tailored to absorb a different part of the light spectrum. Tandem perovskite/silicon cells are closer to market, but all-perovskite tandem cells would be easier and less costly.Making an all-perovskite tandem cell that is efficient has been a challenge. The bottom device in a tandem cell is prepared with a low-bandgap material to absorb all of the infrared photons passing through the top device. Despite many efforts, researchers have had difficulty making high-quality low-bandgap perovskite absorber layers.At the University of Toledo, Yanfa Yan and his colleagues made a high-quality layer by introducing 2.5% chlorine into a mixed tin–lead perovskite. This increased the grain size and crystallinity of the layer and reduced electronic disorder, which quashed the charge-carrier recombinations that produce heat and boost efficiency of the tandem cell. The cell retains 85% of this efficiency after 80 hours.This work was published in a recent issue of Nature Energy.

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.

My name is Bob Braughler. The layered nature of Ruddlesden–Popper perovskites means that the materials can be shaved down to a single layer or just a few layers. The properties of any material at the molecular level are different from those at larger scales. Kian Ping Loh, at the National University of Singapore, and his colleagues have revealed what makes the properties of two-dimensional perovskite differ at molecularly thin dimensions. The researchers made centimeter-sized crystals of a specific perovskite with four compositions with increasing number of atoms and exfoliated 20–100-micron-thick monolayer sheets from the material. They measured the optical properties of the bulk and monolayer flakes using photoluminescence and optical absorption measurements. To keep the flakes from decomposing under laser irradiation used for these studies, they encapsulated the flakes with a transparent 2D hexagonal boron nitride layer.The researchers studied the photoresponsivity of the single-crystal 2D perovskites as a function of thickness and discovered that excitons—which are joint states of an electron and a positively charged hole—tunnel across the material interlayers to dissociate at the electrodes, leading to efficient photocurrent generation. With increasing composition – or number of atoms - the luminescence of the materials shifted toward longer, redder wavelengths. The redshift also happened when the material was exposed to the laser for a long time, because thermal fluctuations reoriented the surface organic cations in the monolayer perovskite. The color shift can be reversed by exposing the sample to higher power laser annealing under vacuum. This cycle could be repeated tens of times.The disordering of the organic cations also creates defects that trap only positively charged carriers, allowing electrons to circulate longer. To test this, the researchers made a photodetector with the monolayer perovskites. The detector had a low current in the dark, but the current increased linearly with laser power because under illumination, excitons tunneled across the interlayers, creating a highly conductive state.This work was published in a recent issue of Nature Materials.

My name is Bob Braughler. A new study offers key insights into the formation of layered two-dimensional perovskite films known as Ruddlesden–Popper phases, a class of materials that hold promise for stable light-harvesting and light-emitting devices.Despite being one of the most attractive materials for photovoltaics and light-emitting devices, conventional three-dimensional organic–inorganic perovskites are plagued by instability issues. However, their 2D counterparts, which contain layers of conductive perovskites separated by layers of relatively long organic cations, are much more stable. The cations inhibit charge transport between neighboring conductive inorganic layers. This forms quantum wells, where the charge carriers can freely move in a 2D space, while there is a restriction in the third dimension.So far, though, not much is understood about their composition or how these materials assemble. To investigate, Edward Sargent and colleagues at the University of Toronto used grazing incidence x-ray scattering on 2D-layered perovskite films as the films formed.They used methylammonium lead iodide with either phenethylammonium or n-butylammonium cations, and different solvents to make various film samples. They found that intermediate solvent complexes mediated the formation of quantum wells by providing building blocks to grow perovskites as the solvent evaporates out. They also found that changing the cation changed the well distribution.This understanding could help control the distribution, composition, and orientation of 2D-layered perovskites, properties that influence device performance. The results could be applied to any such material. The researchers say, “This work paves the way toward engineering higher quality materials for more efficient and stable optoelectronic devices.”This work was published in a recent issue of Nature Materials.

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.

Roland Pease looks into perovskites - the materials enthusiasts say could transform solar power. Solar power is the fastest growing form of renewable energy. But most of it collected by panels made of silicon - the material that also goes into computer chips. But silicon is an old technology, and researchers have long sought a material that is both better at capturing sunlight. And cheaper to make. Perovskites, which first emerged into the lab just a few years ago, promise to be just that material. Roland Pease meets the experts who have made this happen, and finds out what makes perovskites so good - and what wrinkles still have to be ironed out. Image credit: 1999 EyeWire, Inc
