Application of graphene oxide and TiO2 in the fabrication of dye sensitized solar cells module by electrode modification

Abstract

The use of graphene oxide nanosheets as a counter-electrode material substituting platinum in dye-sensitized solar cell (DSSC) shows the cheap way of fabricating DSSC with increase in conversion efficiency. The incorporation of graphene oxide in active electrode increased the conversion efficiency of DSSC significantly. The DSSC was fabricated, which consists of graphene oxide-TiO2 as an active electrode, carbon as a counter-electrode, and electrolyte solution with organic dye, and then they were tested for their photovoltaic performance. The fabricated DSSC compared with the cell which consist of TiO2 only as an active electrode keeping other constituent same. © (2012) Trans Tech Publications, Switzerland.
