In article no. 1900078 , Changlei Wang, Xiaofeng Li, Yanfa Yan, and co‐workers report that the introduction of block copolymer F127 could passivate grain boundaries and enhance the hydrophobicity of perovskite films simultaneously, resulting in highly efficient planar and flexible perovskite solar cells with good stability.
