Abstract

We present a one-step solvothermal approach to prepare uniform graphene-TiO ₂ nanocomposites with delicately controlled TiO ₂ nanostructures, including ultra-small 2 nm nanoparticles, 12 nm nanoparticles and nanorods. Using three composites as photoanode materials, the effect of nanostructure of graphene-composited TiO ₂ on the performance of dye-sensitized solar cells was investigated, and results showed that the ultra-small 2 nm TiO ₂-graphene composite based photoanode exhibited the highest power conversion efficiency of 7.25%.
