Planar perovskite solar cells (PSCs) based on SSE - deposited CH3NH3PbI3 perovskite thin films
deliver power conversion efficiency (PCE) up to 15.2 %, and most notably an average PCE of 10.1 % for PSCs with sub-100 nm semi-transparent perovskite thin films.
The paper PSCs were developed with a low - temperature Paper / Au / SnO2 / meso - TiO2 / CH3NH3PbI3 / Spiro - OMeTAD / MoOx / Au / MoOx architecture utilizing a Au / SnO2 and MoOx / Au / MoOx stack as electron - and hole - extracting electrodes respectively,
delivering state of the art
power conversion efficiency of 2.7 % for solar cells prepared directly on the opaque paper substrate.
