Modulated Diffusion Passivation In article number 1900293 , Jingjing Chang and co‐workers demonstrate a novel solution process to develop 2D/3D perovskites with modulated diffusion passivation by introducing a PEAI and DMF additive, which could effectively enhance device performance and long‐term stability. The solar cells with passivation treatment exhibit a high fill factor of 83.6% and an average power conversion efficiency of 21.4%.
