A polytriarylamine‐based oligomer is reported as a hole transporting material and its application in solid‐state CH 3 NH 3 PbI 3 based heterojunction solar cells is described. It yields a power conversion efficiency of 12.0% under 99.6 mW cm –2 illumination. In addition to suitable energy levels and high hole mobility, the low preparation cost makes it a promising candidate for photovoltaics.
