Reduced graphene oxide films fabricated by gel coating and their application as platinum-free counter electrodes of highly efficient iodide/triiodide dye-sensitized solar cells
Abstract
This paper reports the preparation of reduced graphene oxide (rGO) films through the gel formation of rGO with liquid polyethylene glycol (PEG) of low molecular weight and the application of the rGO films as the platinum (Pt)-free
