Abstract

We report here all inorganic CsPbI 3 planar junction perovskite solar cells fabricated by thermal coevaporation of CsI and PbI 2 precursors. The best devices delivered power conversion efficiency (PCE) of 9.3 to 10.5%, thus coming close to the reference MAPbI 3 -based devices (PCE ≈ 12%). These resu...
