▎ 摘 要
NOVELTY - The electrode has a graphene film layer prepared on back of a plugging-resistant layer. Thickness of the graphene film layer is 0.1 microns to 1 millimeter. Thickness of a glass substrate is 1-3 millimeters and the thickness of an upper conductive layer is 300 nanometers to 3 microns. Thickness of a window layer i.e. cadmium sulphide, is 20 nanometers to 300 microns. Thickness of a light absorption layer i.e. cadmium telluride, is 600 nanometers to 10 microns. A shielding layer is provided with zinc telluride/copper-doped zinc telluride compound layer. USE - Back contact electrode for use in a cadmium telluride (CdTe) film solar cell structure. ADVANTAGE - The electrode is inexpensive, and has high-performance, and ensures large-scale production of CdTe battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a back contact electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a back contact electrode.'(Drawing includes non-English language text)'
