▎ 摘　　要

Dye-sensitized solar cells (DSSCs) based on TiO2 film photoanode incorporated with different amounts of graphene are fabricated and their photovoltaic performances are investigated. The results show that DSSCs incorporating 1.6 wt.% graphene in TiO2 photoanode demonstrates a maximum power conversion efficiency of 3.69% under air mass (AM) 1.5 G at 60 mW cm(-2) illumination, 48% higher than that without graphene. The performance improvement is ascribed to the increased dye adsorption amount and the enhanced light scattering as well as the reduction of electron recombination and the enhancement of electron transport in TiO2 film with the introduction of graphene.
