▎ 摘　　要

We have demonstrated that a partially-reduced graphene oxide (GO) film exhibits good catalytic effects in a dye-sensitized solar cell (DSSC). We obtained a solar power conversion efficiency (eta) of 1.6%, a short-circuit current density of 10.6 mA/cm(2), an open current density (V(oc)) of 0.68 V, and a fill factor (FF) of 0.22. The eta was higher than the eta of a DSSC without catalysis (0.74%) and the reported eta of other DSSCs (0.84%) and organic solar cells (1.1%) with conductive graphene electrodes. The catalytic effect is explained by using the ion conductivity of the GO film.
