The dye-sensitized solar cell (DSSC) is a promising alternative to the Si solar cell because of its low-cost and easy fabrication. The conductive polymer counter electrode, PEDOT has attracted much attention on DSSCs. To enhance efficiency, the electrochemical deposition of PEDOT onto FTO glass was carried out in 4 solution deposition ratios 4:6, 6:4, 8:2 and 9:1 of distilled water and acetonitrile. The best efficiency of the resulting DSSCs with 9:1/ PEDOT as compared to the reference cell. The excellent photoelectric properties, and low cost allow the PEDOT electrode to be a credible alternative electrode for use in DSSCs.
