It is shown that by chemically doping the carbazole-based conjugated polymer PCDTBT using the molecular materials TBP, LiTFSI and FK209, its conductivity can be increased by a factor of 105 times. Such doped PCDTBT films are used as a hole transport material (HTM) for standard architecture (CH(NH2)2PbI3)0.85(CH3NH3PbBr3)0.15 perovskite solar cells…
