A Catalytic Graphene Oxide Film for a Dye-sensitized Solar Cell
- ?We have demonstrated that partially reduced graphene oxide (GO) film exhibits good catalytic effects in a dye-sensitized solar cell (DSSC). We obtained a solar power conversion efficiency (?) of 1.6%, a short-circuit current density (Jsc) of 10.6 mA/cm2, an open current density (Voc) of 0.68 V, and a fill factor (FF) of 0.22. The ? was higher than the ? of a DSSC without catalysis (0.74%) and the reported ? of other DSSCs (0.84%) and organic solar cells (1.1%) with conductive graphene electrodes. The catalytic effect is explained by the ion conductivity of the GO film.
