Abstract

Two simple biphenyl or carbazole derivatives with four di(anisyl)amino substituents were synthesized and used as hole-transporting materials (HTMs) for FAxMA1?xPbI3?yBry perovskite solar cells. The best power conversion efficiencies of 13.6% and 11.5% were achieved, respectively. The simple structures, easy synthesis, and good photovoltaic performances of these HTMs make them promising for practical applications.
