Conducting AFM reveals a continuous conduction network of a TiO2-graphene composite in DSSC due to a more intimate contact between the smaller sized TiO2-graphene composite nanosheets,which reduces the internal resistance at TiO2/TiO2 and TiO2/FTO interfaces and ultimately leads to a faster and more efficient electron transport in the photoanode.
