In this work, we propose a new characterization technique to resolve both the spatial and energetic distributions of trap states in metal halide perovskite single-crystalline and polycrystalline solar cells. This work answered long-standing question like why single crystal perovskite solar cells are not better polycrystalline solar cells and pointed out a direction to further improve the efficiency of perovskite solar cells by reducing both the surface and bulk trap densities in perovskites through new synthesis.
