▎ 摘　　要

NOVELTY - The battery has a back electrode (1) connected with a n-type doped or p-type doped gallium arsenide layer (2). A front face (4) of a graphene (3) is connected with the gallium arsenide layer. USE - Graphene/gallium arsenide solar battery. ADVANTAGE - The battery has high current carrier migration rate of graphene material, high light transmittance, high conductivity, low cost and simple technique, and high conversion efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene/gallium arsenide solar battery manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a graphene/gallium arsenide solar battery. Back electrode (1) N-type doped or p-type doped gallium arsenide layer (2) Graphene (3) Front face (4)
