Abstract

Gold doped reduced graphene oxide (rGO) films prepared via hummer method have been utilised as counter electrode of dye-sensitised solar cell. The samples were subjected to various annealing times at 120°C. The effect of annealing time on the dark current and photovoltaic performance has been investigated. The power conversion efficiency varies with annealing time. The highest efficiency of 0.155% was achieved by the device utilising gold doped rGO annealed for 45 min. This is due to the device employing this sample possesses the smallest leak current.
