▎ 摘　　要

NOVELTY - The solar energy battery structure from upper to lower has a metal electrode (1), a wide band gap graphene layer (2), cadmium selenide nano stack (3), a narrow band gap graphene layer (4) and metal lower electrode (5). The cadmium selenide nano layer is provided with a multi-cadmium selenide solar cell with band gap width. USE - Laminated solar energy battery based graphene and cadmium selenide nano structure. ADVANTAGE - The graphite target is excellent, so as to increase cell photoelectric conversion efficiency of solar energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of solar energy battery structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the Graphene and cadmium selenide nano based laminated solar energy battery structure.
