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.
