Abstract

Conducting AFM reveals a continuous conduction network of a TiO ₂-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 TiO ₂/FTO interfaces and ultimately leads to a faster and more efficient electron transport in the photoanode.
