Perovskite

The state of the art in perovskite tandems

A new paper from scientists in China and Canada examines the recent progress in the development of perovskite-silicon tandem cells, finding a technology that’s poised for rapid commercialization, with a few research challenges still to overcome. These are primarily related to ensuring the perovskite layer can match the lifetime of the silicon cell underneath.

Stanford scientists gain insight on polaron distortion in perovskite solar cells

Polaron formation in perovskite solar cells has been indicated in scientific research as a possible factor for making this kind of cell particularly efficient, although the mechanism behind polarons’ action is completely unknown. A U.S. research group has now observed how polaron distortions form and grow.

New manufacturing process for 15.5% efficient perovskite solar panels

Stanford scientists have used a robotic device with two nozzles to quickly produce thin films of perovskite. With these films, they have manufactured perovskite cells and modules with efficiencies of 18% and 15.5%, respectively. According to them, this technique may enable the production of perovskite modules at a cost of around $0.25 per square foot.
