NOVELTY - The utility model claims a solar battery structure, especially an organic solar battery structure containing graphene middle layer, comprising a cathode and a positive electrode, wherein the cathode and the anode are orderly provided with an active layer, a graphene layer, a ZnO nano-structure layer and PEDOT: PSS layer. the ZnO nano-structure layer has a one-dimensional ordered nano structure, which is densely and uniformly grown on the surface of the graphene layer; it can be well connected with the graphene, so that the hole transmitted from the graphene maintains high-efficient transmission, and is not easy to quench. The utility model claims a solar battery, so that more holes reach the anode of the organic solar battery, so as to effectively improve the photoelectric conversion efficiency of the organic solar battery.
