▎ 摘　　要

NOVELTY - The homogeneous perovskite film solar battery has a transparent conductive substrate (1), a P-type perovskite film (2), an N-type perovskite film (3), an anti-reflection layer (4), and a metal electrode (5). The transparent conductive substrate is ITO conductive glass or FTO conductive glass or graphene or organic flexible transparent conductive plastic. USE - Homogeneous perovskite film solar battery. ADVANTAGE - The stability of the perovskite thin film solar cell and the photoelectric conversion efficiency are improved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of homogeneous perovskite film solar battery. Transparent conductive substrate (1) P-type perovskite film (2) N-type perovskite film (3) Anti-reflection layer (4) Metal electrode (5)
