▎ 摘　　要

NOVELTY - The method involves synthesizing graphene (10) on a metal foil, and removing the metal foil. A photoelectrode (13) is formed on a metal substrate in which graphene is grown up. The photoelectrode made of titanium dioxide (TiO2) nano particle is plasticized on the graphene film. The plastic substrate is made of polyethylene, polypropylene, polyester, polyacryl, polyimide, polyamide or polystyrene group polymer. USE - Method for manufacturing solar cell such as dye-sensitized solar cell mounted in vehicle. ADVANTAGE - The flexible type solar cell with improved performance can be manufactured easily. The cost and weight of the solar cell can be reduced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a solar cell. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the solar cell. Solar cell board (1) Transparent electrode (2) Electrolyte (5) Graphene (10) Photoelectrode (13)
