▎ 摘　　要

NOVELTY - The method involves forming a graphene oxide film on an anodic aluminum oxide base film. The anodic aluminum oxide base film is placed on water surface. The graphene oxide film is floated on the water surface. The graphene oxide film is lifted from the water surface by using a silicon wafer. The graphene oxide film is arranged on a surface of a substrate. Moisture in the graphene oxide film is removed at room temperature. The graphene oxide film after evaporation is freeze-dried. The graphene oxide film is detached from the surface of the silicon wafer. Temperature of the graphene oxide film is reduced to specific range. USE - Graphene-film based solar battery manufacturing method. ADVANTAGE - The method enables controlling thickness of the graphene oxide film to nanometer level so as to improve light transmittance of the graphene oxide film. The method enables generating microscopic wrinkles to increase contact area between the graphene oxide film and a photosensitive layer during transfer process so as to increase strength of the graphene oxide film, stress change capability during folding of a flexible electrode, electron mobility and avoid heavy metal pollution problem, reduce battery manufacturing cost and improve light conversion efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a solar battery. '(Drawing includes non-English language text)'
