A low cost, chemically stable with enhanced electrocatalytic activity counter electrodes based on reduced graphene oxide (RGO) coating was easily deposited on fluorine doped tin oxide (FTO) substrate was developed for CdS QDSSCs. Polyvinylidene fluoride (PVDF) was used as a binder for the coating to increase the mechanical stability of RGO counter electrode through increasing its adhesion on the FTO substrate. The structure and morphology of RGO powder were analysed by UV-visible, FTIR spectroscopy, X-ray powder diffraction, and SEM microscopy. The electrocatalytic activity of RGO counter electrodes were investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The QDSSCs assembled using RGO counter electrode shows a high short circuit current reaches to a value of 2.843 mA cm and yields power conversion efficiency (PCE) of 0.52%. An enhancement 46.3% in the fill factor (FF) also was achieved with RGO as a counter electrode when compared to expensive traditional Pt thin film counter electrode. The unique electrocatalytic activity of the tailored RGO electrode was discussed in terms of its high electrical conductivity and large surface area.
