By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Science. According to news reporting originating in Oxford, United Kingdom, by NewsRx journalists, research stated, "Many different photovoltaic technologies are being developed for large-scale solar energy conversion(1-4). The wafer-based first-generation photovoltaic devices(1) have been followed by thin-film solid semiconductor absorber layers sandwiched between two charge-selective contacts(3) and nanostructured (or mesostructured) solar cells that rely on a distributed heterojunction to generate charge and to transport positive and negative charges in spatially separated phases(4-6)."
The news reporters obtained a quote from the research from the University of Oxford, "Although many materials have been used in nanostructured devices, the goal of attaining high-efficiency thin-film solar cells in such a way has yet to be achieved(7). Organometal halide perovskites have recently emerged as a promising material for high-efficiency nanostructured devices(8-11). Here we show that nanostructuring is not necessary to achieve high efficiencies with this material: a simple planar heterojunction solar cell incorporating vapour-deposited perovskite as the absorbing layer can have solar-to-electrical power conversion efficiencies of over 15 per cent (as measured under simulated full sunlight)."
According to the news reporters, the research concluded: "This demonstrates that perovskite absorbers can function at the highest efficiencies in simplified device architectures, without the need for complex nanostructures."
