Abstract

Exfoliated graphene sheets (EGS) are obtained using simple liquid phase sonication and then mixed with TiO₂ nanoparticles in a dye sensitized solar cell photoanode to achieve higher electrical conductivity and faster electron transfer due to much fewer defects as compared to conventional reduced graphene oxide (RGO): I_D/I_G of 0.256 in EGS as compared with that of 1.128 in RGO. The EGS-TiO₂ photoanode yields a conversion efficiency of 8.24%, over a 19% increase compared with that of the RGO-TiO₂ photoanode, and a 43% increase over that of TiO₂ alone under the same conditions.
