Highly efficient (17.3%, aperture area = 1 cm 2 ) and stable semitransparent CH(NH 2 ) 2 PbI 3- x Br x (FAPbI 3- x Br x ) perovskite solar cells (PSCs) are demonstrated by lamination process through conductive poly[(2,5-bis(2-hexyldecyloxy)phenylene)-alt-(5,6-difluoro-4,7-di(thiophen-2-yl)benzo[c][1,2,5]-thiadiazole)] doped with nonhygroscopic tris(pentafluorophenyl)borane hole transporting glue layer. Due to the self-passivated structure of semitransparent PSCs, the edge-encapsulated PSC exhibits 5.20% degradation compared to its initial efficiency during 1000 h maximum power point tracking under simultaneous damp heat (85 °C/85% relative humidity) and 1 sun light soaking test condition. In addition, 14.3% of full flexible semitransparent PSC with good mechanical bending stability is demonstrated by the same lamination process.
