Electrochemical synthesis of graphene oxide and its application as counter electrode in dye sensitized solar cell
Graphene oxide sheets were prepared by simple electrochemical method for its application as counter electrode in Dye Sensitized Solar Cell (DSSC). To develop counter electrode, graphene oxide sheet is coated on the Fluorine doped Tin Oxide (FTO) glass and is characterized using various techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and solid state C-13 NMR. The XRD pattern as well as C-13 NMR confirms the formation of grapheme oxide while FTIR confirms the oxidation of the graphite. SEM was used to study about surface morphology of grapheme oxide. The graphene oxide thus obtained is tested as counter electrode in DSSC. The DSSC using graphene oxide as a counter electrode and solid polymer electrolyte shows an overall efficiency of 0.27% with a fill factor of 0.66 at 1 sun condition. The present study shows that graphene oxide can be obtained using simple, economic, and eco-friendly method and further apply in DSSC application.
