The surfaces of polycrystalline perovskite films impact the long-term performance of perovskite solar cells, yet their microstructure is not well understood. Research now reveals the existence of concave grain structures at the surface of the perovskite layer facing the electron transport layer, and their detrimental effect on the stability of the interface and eventually the devices.
