Effect of annealing temperature of gold doped reduced graphene oxide counter electrode on the performance of dye-sensitized solar cell

Research output: Contribution to journalArticle

Abstract

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 °C sample possesses the highest transmission in visible region. The DSSC utilizing the sample annealed at 120 °C performed the highest η of 0.134%, respectively due to the longest carrier lifetime.
