Graphene Infrared Transparent Electrode (GITE) and Thermal Enhancer for the Hybrid Energy Nanodevice

Abstract

This work investigated the use of graphene nanosheets (GN) as a cost-effective replacement for platinum to form the counter electrode(CE) 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 .
