NOVELTY - The utility model claims a graphene conductive material as perovskite thin film solar cell, wherein the structure of the solar cell from down to up as the transparent conductive substrate 1, an N-type perovskite film 2, P-type graphene film 3, metal electrode 4. and perovskite solar battery in the traditional structure, the utility model has the following advantages: by using graphene film the unique permeability, and a perovskite thin film solar cell PN junction, which can effectively prevent the high temperature metal electrode to harmful diffusion of the perovskite layer, and can effectively prevent water and oxygen in the air from entering the perovskite layer to make it decompose so as to greatly improving stability and thermal stability of the water oxygen perovskite solar battery and prolong its service life. And, the high conductivity and transmittance of the graphene, it greatly improves the output power and the photoelectric conversion efficiency of the perovskite solar cell.
