This work is concerned with the use of gold doped reduced graphene oxide (rGO) films as counter electrode in a dye-sensitized solar cell (DSSC). The effect of gold content on the photovoltaic parameters of the device has been studied. The samples are crystalline, indicated by the presence of rGO phase. It was found that the short-circuit current density (JSC) decreases with the increase in gold content. The DSSC utilizing the sample prepared using 2.0 wt.% gold demonstrated the highest JSC, Voc and η of 0.989 mA cm-2, 0.692 V and 0.175%, respectively. The highest efficiency (η) of the device is due to the lowest leak current and charge transfer resistance (Rct).
