This work investigated the use of graphene nanosheets GN as a cost-effective replacement for platinum to form the counter electrodeCE in a dye-sensitized solar cell DSSC. The GN counter-electrode properties were characterized by scanning electron microscopy SEM, atomic force microscopy AFM, Raman spectroscopy, X-ray photoelectron spectroscopy XPS, energy dispersive spectroscopy EDS, and cyclic voltammogram CV, and the characteristics of the DSSCs based on the various CEs were analyzed using J-V measurements, incident monochromatic photon-to-current conversion efficiency IPCE, and electrochemical impedance spectroscopy EIS measurements. This study also investigated two novel GN-based CEs for DSSCs. The results show that the DSSCs based on conventional Pt CEs yielded an efficiency of 7.32 .
