The dye-sensitized solar cell (DSSC) plays a leading role in third generation photovoltaic devices. Platinum nanoparticles-coated conducting glass has been widely used as the standard counter electrode (CE) for DSSCs. However, the high cost and the rarity of platinum limits its practical application in DSSCs. This has promoted large interest in exploring Pt-free CEs for DSSCs. Very recently, graphene, which is an atomic planar sheet of hexagonally arrayed sp2 carbon atoms, has been demonstrated to be a promising CE material for DSSCs due to its excellent conductivity and high surface area, as well as high electrocatalytic activity. Here, we demonstrate a facile method for the fabrication of reduced graphene oxide films on a FTO glass and it application as a counter electrode for platinum-free DSSC. The RGO-based CEs were produced by spinning coating deposition of GO and low temperature chemical vapor |
