A recent study, affiliated with Ulsan National Institute of Science and Technology (UNIST) finds key to produce a new cost-efficient way to fabricate inorganic-organic hybrid perovskite solar cells (PSCs) which sets a new world-record efficiency performance of 22.1 % in small cells and 19.7 percent in 1-square-centimeter cells.
A Korean research team has created semi-transparent perovskite solar cells that demonstrate high-power conversion efficiency and transmit visible light while blocking infrared light, making them great candidates for solar windows.
Researchers at École polytechnique fédérale de Lausanne (EPFL), Michael Graetzel and his team, found that, by briefly reducing the pressure while fabricating perovskite crystals, they were able to achieve the highest performance ever measured for larger-size perovskite solar cells, reaching over 20% efficiency and matching the performance of conventional thin-film solar cells of similar sizes. Their results are published in Science.
Oxford Photovoltaics, the pioneering UK solar technology company, today announces that it has raised a first-tranche B round of over £8 million from a variety of new and existing investors.
