More Information
Summary:The invention discloses a laminated solar cell based on a graphene and cadmium selenide nanostructure and a manufacturing method thereof. The laminated solar cell is characterized in that the solar cell is structurally provided with an upper metal electrode 1, a board-band gap graphene laminating layer 2, a cadmium selenide nano laminating layer 3, a narrow-band gap graphene laminating layer 4 and a lower metal electrode 5 which are sequentially arranged from top to bottom. The laminated solar cell has the advantages that by combining the graphene laminating layers of different band widths with the cadmium selenide laminating layer, solar light can be completely absorbed, excellent conductivity of the graphene can be sufficiently developed, and the purpose for improving photoelectric conversion efficiency of the solar cell is finally achieved.
