Abstract

Abstract : In article number 1901268, Ning Cai, Sai‐Wing Tsang and co‐workers present a dopant‐free coplanar D‐π‐D hole‐transporting material which is deployed in inverted planar perovskite solar cells, achieving a high fill factor of 81.7% and an excellent power conversion efficiency of 19.16%. By comparison with a counterpart, a correlation between the molecular packing, hole mobility and device performance is revealed, providing insights for the rational design of hole‐transporting materials.
