Electrophoretic graphene for transparent counter electrodes in dye-sensitised solar cells

Graphene counter electrodes (GCEs) prepared by electrophoretic deposition (EPD) have been investigated. Half cells were fabricated to examine the electrochemical properties of GCEs with different deposition times. Accordingly, dye-sensitised solar cells (DSSCs) were fabricated with those GCEs in order to examine the conversion efficiencies and effect of GCEs with different deposition times. The possibility of GCEs by EPD as a counter electrode of DSSCs is suggested.
