Perovskite Solar Cells >20% Efficiency Enabled by A Vacuum Flash–assisted Solution Process

Posted Jun 10, 2016

EPFL's 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.
