Dye-sensitised solar cells (DSSCs) are one of the promising prospects for efficient renewable resources. To bring DSSCs to the point of commercial readiness and viability in terms of performance and cost, substantial research on the development of a high efficiency DSSCs system is necessary. Our recent studies have indicated that a maximum conductivity of 29.1 mu S/cm and conversion efficiency of 4.76% under 1.5 AM condition was successfully achieved from 0.2 wt% TiO2 loaded on reduced graphene oxide (rGO) forming a nanocomposite film, which is approximately twice or three times higher than that of pure rGO nanosheets and anatase TiO2 film. The findings were mainly attributed to the fact that rGO nanosheets could further increase the photo- induced electron transportation rate and minimise the recombination losses within the TiO2 lattice in this binary hybrid photoelectrode.
