    Optically Transparent Cathode for Co(III/II) Mediated Dye-Sensitized Solar Cells Based on Graphene Oxide

  • Original language description

    Thin semitransparent films were fabricated on F-doped SnO2 (FTO) from single-layer graphene oxide (GO) either pure or in a composite with graphene nanoplatelets. Electrocatalytic activity of prepared films was tested for the Co(bpy)33+/2+ redox couple inacetonitrile electrolyte solution. Pristine GO showed almost no activity, resembling the properties of basal plane pyrolytic graphite. However, electrochemical performance of graphene oxide improved dramatically upon chemical reduction with hydrazine and/or heat treatment. All GO-containing films were firmly bonded to FTO, which contrasted with the poor adhesion of sole graphene nanoplatelets to this support. The activity loss during long-term aging was considerably improved, too. Enhanced stability ofGO-containing films together with high electrocatalytic activity is beneficial for application in a new generation of dye-sensitized solar cells employing Co(bpy)33+/2+ as the redox shuttle.
