title: Understanding TiO(2) size-dependent electron transport properties of a graphene-TiO(2) photoanode in dye-sensitized solar cells using conducting atomic force microscopy.
abstract: 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.
