Abstract:Defect‐induced recombination dynamics remain an essential factor hindering the efficiency and stability of perovskite solar cells (PSCs). Herein, an upgraded solvent posttreatment strategy is proposed to simultaneously improve the quality and related electronic properties of absorbers by introducing the black phosphorus–graphene oxide (BP–GO) composites with a unique microscopic heterojunction stacking structure, high charge mobility, tunable bandgap, and excellent surface chemical properties into the grain bo… Show more
