Graphene-based cathode materials for dye-sensitized solar cells: a review


In recent years, color-sensitive solar cells (DSSCs) have gained widespread attention for serving as potentially low-cost alternatives to silicon-based solar cells. In DSSCs, platinum-based materials (Pt) used as counter-electrodes (CEs) show superior catalytic ability than triiodide ion reduction reactions, which are attributed to their excellent catalytic activity and high electrical conductivity. However, in order to achieve cost-effective DSSCs, reasonable efforts have been made to discover alternatives without Pt. Recently, a large number of ground-based catalysts, especially carbon-based materials, have shown high activity, low cost, and good stability, making them attractive candidates for platinum replacement in DSSCs. Recently, inexpensive graphene-based counter (CE) electrodes have been developed that could serve as a potential alternative to expensive platinum-based CEs. In this review article, the development of DSSCs and the properties of graphene are briefly described. Then, the application of graphene-based materials for photo electrodes (transparent electrode, semiconductor layer, and color sensitizer) in DSSCs is discussed in depth. Finally, we have a comprehensive perspective on graphene materials in DSSCs is presented.
