Cross-sectional SEM picture of perovskite film, control group (E), experimental group (F)In metal halide perovskite materials, serious non-radiative recombination is prone to occur at the interface between grain aggregates at the submicron scale, which in turn affects carrier transport, promotes ion migration, and introduces deep energy level defects, resulting in a decrease in the efficiency and stability of perovskite solar cells.
