▎ 摘　　要

NOVELTY - The method involves successively forming a molybdenum layer coating, a copper indium gallium selenium thin film, a cadmium sulfide thin film and an intrinsic zinc oxide thin film on a substrate. A composite thin film that carries graphene is utilized to encapsulate the molybdenum layer coating, copper indium gallium selenium thin film, cadmium sulfide thin film and intrinsic zinc oxide thin film, where the graphene-based composite thin film comprises a graphene thin film and a nanowire placed on the graphene thin film. USE - Method for preparing a copper-indium-gallium-selenium solar cell assembly. ADVANTAGE - The method enables utilizing the composite thin film that carries graphene to encapsulate the molybdenum layer coating, copper indium gallium selenium thin film, cadmium sulfide thin film and intrinsic zinc oxide thin film, thus improving conversion efficiency of the copper-indium-gallium-selenium solar cell assembly. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a copper-indium-gallium solar battery assembly (2) a method for manufacturing a copper-indium-gallium-selenium solar battery component.
