Electrodes play a crucial role in the efficiency, stability and overall performance of next-generation optoelectronic devices, particularly solar cells [1]. Transparent electrodes on the top of solar cells can enhance power conversion efficiency by maximizing the light absorption and facilitates the efficient charge collection [2]. This study provides a comparison of graphene-based electrodes with ITO and hybrid ITO/graphene materials in terms of electrical conductivity. A detailed analysis would be conducted to evaluate charge transport behavior and nanoscale electrical properties. The graphene electrodes are prepared by cold wall chemical vapor deposition method and are experimentally verified by Raman spectroscopy. ITO electrodes are commercially obtained and used as a base for hybrid ITO/graphene electrodes. The results provide insights into the feasibility of referring a material as a superior transparent electrode, highlighting its advantages and limitations compared to conventional materials. This work contributes to optimizing electrodes selection for applications in solar cells, displays, and flexible electronics.
