▎ 摘　　要

NOVELTY - The solar cell has a gallium arsenide solar cell epitaxial structure whose first and second surfaces are arranged with a first electrode and a second electrode. The first surface and the second surface are opposite to each other. The first electrode is a fully transparent electrode including a graphene layer. A highly doped gallium arsenide contact layer is formed between the gallium arsenide solar cell epitaxial structure and the graphene layer. The graphene layer forms an ohmic contact with the gallium arsenide solar cell epitaxial structure through the gallium arsenide contact layer. USE - Flexible solar cell. ADVANTAGE - The flexible solar cell uses the graphene layer as the first electrode of the gallium arsenide solar cell, thus the first electrode effectively improve the current collecting ability of the electrode, reduces the series resistance, reduces the shading loss, and helps the gallium arsenide solar cell to obtain more high open circuit voltage, short circuit current and photoelectric conversion efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method of flexible solar cell. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the forward-growing gallium arsenide multi-junction solar cell epitaxial wafer. (Drawing includes non-English language text)
