Abstract

Abstract : Solar Cells In article number 2108090, Gang Wang, Hao‐Li Zhang, Zhiwen Jin, and co‐workers propose a C3 N quantum dots insertion method to effectively adsorb bulky organic cations, and provide nucleation sites to realize gradient distribution of solute in 2D CsPbI3 film to obtain a bi‐directional crystallization process. Importantly, the optimized 2D CsPbI3 film‐based device delivers a high power conversion efficiency of 15.63% with strengthened environmental stability, and also versatility to other RP and DJ‐type bulky organic molecules.
