Abstract

Abstract : A series of simple alkylated triphenylamine molecules are designed and synthesized as hole transporting materials (HTMs) for perovskite solar cells. The effects of the alkyl chains on the photovoltaic performance are for the first time systematically investigated. A high efficiency of 17.33% is achieved by combining HTM X21 and the mixed‐ion perovskites.
