Utilizing reduced graphene oxide for achieving better efficient dye sensitized solar cells

In the last couple of years the use of carbon allotropes in energy generating and energy storage devices has increased owing to their exceptional properties. In applications where charge transfer is required, reduced graphene oxide (rGO) is the preferred choice. The current work reports the synthesis of rGO by microwave and electrochemical method. Further the rGO have been used in the working electrode of DSSC in various configurations. Using quasi-solid polymer electrolyte we obtained a short circuit current density (J(sc)) of 2.15mA/cm(2), open circuit voltage (V-oc) of 0.54 V and an efficiency (eta) of 0.58%. Because of the presence of polymer electrolyte the cell parameters improved after a period of 72 h and the same have been presented with their electrochemical impedance studies.
