Solar Technology & PV R&D News

Mass adoption of perovskite solar cells will certainly never be commercially viable unless the technology gets over several key obstacles, according to scientists from the University of Surrey.

Scientists from the University of Surrey, University of Toronto, University of Stuttgart as well as Ulsan National Institute of Science and also Technology have actually found that supporting the perovskite "photoactive phases"-- the certain part of the product that is in charge of transforming light power right into electrical energy-- is the key action towards expanding the life-span of perovskite solar cells.

A worldwide research group that includes scientists from EPFL in Switzerland, Middle East Technical University (METU) in Turkey, Lomonosov Moscow State University in Russia as well as The University of Tokyo has actually produced a quasi-2D perovskite solar cell with a unique type of salt to enhance hole extraction.

Prof. Ye Jichun's team at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) has actually created a long-alkyl- chain anionic surfactant (LAS) additive that can significantly improve the lasting operational stability of perovskite/silicon tandem solar cells. The research study was published in Nature Communications.

Organic solar cells have a photoactive layer that is made from polymers and tiny molecules. The cells are very slim, can be flexible, as well as are simple to make. Nonetheless, the effectiveness of these cells is still much below that of standard silicon-based ones.

Making solar cells more efficient is an obvious win for green power. It indicates more electrical power from the very same number of panels as well as the exact same amount of sunlight-- and also scientists are working hard to tackle the challenge.

Our modern-day rechargeable batteries, such as lithium-ion batteries, are anything however sustainable. One alternative is organic batteries with redox-organic electrode materials (OEMs), which can be synthesized from natural "green" materials. In the journal Angewandte Chemie, a Chinese team has actually currently presented a new OEM for aqueous organic high-capacity batteries that can be quickly and cheaply recycled.

Last summer season, cities of Korea including Seoul were hit by an unmatched heavy rainfall, which swamped various locations. In a similar way, torrential downpours engulfed concerning one-third of Pakistan, resulting in prevalent flooding. New York City State was not spared as it experienced heavy snow storms in December of last year, with snowfall of more than one meter.

Perovskite solar cells (PSCs) are taken into consideration an appealing candidate for next-generation photovoltaic innovation with high effectiveness and low manufacturing cost, potentially changing the renewable energy industry. However, the existing layer-by-layer production process presents challenges that have actually hindered the commercialization of this technology.

Researchers from Tohoku University as well as Tokyo Institute of Technology (Tokyo Tech) have proposed a simple sol-- gel method for the synthesis of extremely pure bifunctional solid acid − base catalysts of perovskite-type oxides.

Because of the current improvements in the efficiency with which solar cells made from organic (carbon-based) semiconductors can transform sunlight right into electricity, improving the long-term security of these photovoltaic or pv devices is ending up being a progressively vital subject. Real-world applications of the innovation demand that the efficiency of the photovoltaic or pv device be preserved for several years.

A research study team led by Prof. Meng Qingbo from the Institute of Physics (IOP) of the Chinese Academy of Science (CAS) as well as Prof. Xin Hao from Nanjing University of Posts as well as Telecommunications has actually reported 13.8% accredited effectiveness of emerging kesterite solar cells. The research study was released in Nature Power on April 13.

Researchers at the University of California, Davis College of Engineering are making use of machine learning to identify new materials for high-efficiency solar cells. Making use of high-throughput experiments and also machine learning-based formulas, they have actually found it is possible to anticipate the products' dynamic behavior with really high accuracy, without the demand to carry out as many experiments.

Scientists at Saudi Arabia's King Abdullah University of Science and also Technology (KAUST) have actually established a perovskite/silicon tandem solar cell with the world's highest possible power conversion effectiveness (PCE) of 33.2%, according to an announcement on Monday.

Perovskite solar films developed by a graduate student in the Department of Physics at UC Merced while on an internship at NASA Glenn Research Center (GRC) not just survived 10 months in space with minimal degradation, but the little damage they did incur was greater than 90% relatively easy to fix.
