Popis: | Carbon double bond-free printed solar cells have been fabricated with the structure and , in which CuSCN acts as a hole conductor. The thickness of the CH3NH3PbI3 layer is controlled by a hot air flow during spin coating. The best conversion efficiency (4.86 %) is obtained with . However, a thick CH3NH3PbI3 layer on CuSCN is better for light-exposure stability (100 mW cm−2 AM 1.5) when not encapsulated. Without the CuSCN coverage, the black CH3NH3PbI3 crystal changes to yellow during the light-exposure stability test, which is due to the transformation of the CH3NH3PbI3 perovskite crystal into hexagonal PbI2. |
