Electron‐Transport‐Layer‐Assisted Crystallization of Perovskite Films for High‐Efficiency Planar Heterojunction Solar Cells

Crystal engineering of CH3NH3PbI3 perovskite materials through template‐directed nucleation and growth on PbI2 nuclei dispersed in a polar fullerene (C60 pyrrolidine tris‐acid, CPTA) electron transport layer (ETL) (CPTA:PbI2) is proposed as a route for controlling crystallization kinetics and grain...
