NOVELTY - This utility new type claims a graphene electrode one flexible perovskite thin film solar energy battery, comprising cathode substrate, a photovoltaic layer is nagetive on a substrate and anode substrate of the photovoltaic material layer on said anode substrate comprising mainly graphene formed by graphene positive electrode, a cathode substrate including main graphene formed by graphene negative electrode, a photovoltaic material layer as the main by perovskite forming a perovskite layer. This utility new type a specific comprise from up to lower orderly arrangement of a substrate, and a graphene, calcium titanium ore layer, graphite negative electrode, lower substrate five layer structure. This utility new type has simple structure, a wet film molding, the cost is low, the cost of silicon solar energy battery 60%, energy conversion efficiency is better than the traditional of silicon solar energy battery, energy conversion efficiency is high is 20 to 26% degrees centigrade, replacing a single flexible thin film solar energy battery as a new one.
