Abstract
Dye-sensitezed solar cell(DSSC) has aroused intense interest owing to its competitive price and stabilized properties than Si based solar cells. Recently, many studies have been reported on the DSSC, especially development of Pt-free counter electrode. In this paper, graphene is chosen counter electrode for low cost material and developed its properties. To estimate the properties of counter electrode, graphene and Pt thin films have been fabricated on FTO substrates respectively, than the films are tested AFM and J-V evaluation method. A graphene of 0.1 wt% has shown current density of 11.68 mA/cm2, maximum efficiency of 4.34% which is similar with that of Pt counter electrode. It confirmed that graphene could be good material for counter electrode if its synthesizing conditions were developed.
