This paper is concerned with the use of gold doped reduced graphene oxide (rGO) films, replacing costly platinum films as a counter electrode in dye-sensitized solar cell (DSSC). The influence of annealing treatment of the electrode on the performance parameters of the device has been investigated. The XRD analysis reveals that crystallite size of GO increases with annealing temperature. The 140 degrees C sample possesses the highest transmission in visible region. The DSSC utilizing the sample annealed at 120 degrees C performed the highest eta of 0.134%, respectively due to the longest carrier lifetime.
