Abstract

Dye-sensitized solar cells (DSSCs) based on TiO2 film photoanode incorporated with differentamounts of graphene are fabricated and their photovoltaic performances are investigated. Theresults show that DSSCs incorporating 1.6 wt.% graphene in TiO2 photoanode demonstrates amaximum 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 theincreased dye adsorption amount and the enhanced light scattering as well as the reduction ofelectron recombination and the enhancement of electron transport in TiO2 film with the introductionof graphene.
