▎ 摘　　要

NOVELTY - A composite light anode is graphene/titanium oxide nano particle composite layer as barrier layer, titanium oxide nano wire array and titanium oxide nano particles filled in titanium oxide nano wire array. The nano particle is grown in graphene/titanium oxide nano particle composite layer as seed crystal. USE - Composite light anode used in dye sensitized nano crystalline solar cell. ADVANTAGE - The composite light anode is efficiently prepared. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite light anode, which involves preparing uniform graphene/titanium oxide nano particle thin film as barrier on fluorine-doped tin oxide glass and titanium oxide nano particle as seed crystal for growth titanium nano wire array, growing aluminum-titanium oxide nano wire array, attaching titanium oxide nano particle on titanium oxide nano wire array, calcining prepared composite structure in nitrogen atmosphere and assembling sensitized light anode and battery.
