By tweaking the chemical composition of the material to create a 'triple' perovskite, scientists at the U.S. National Renewable Energy Laboratory say they have overcome one of the technology's inherent stability issues and fabricated a perovskite cell which achieved 27% efficiency in a tandem format with a silicon device.Though perovskite solar cells look to be well on the way to mass production, interest in the technology is still tempered by concerns about the stability of the material and its sensitivity to atmospheric conditions. Scientists at the United States National Renewable Energy ...Den vollständigen Artikel lesen ...
