ClO4--poly(3,4-ethylenedioxythiophene)TiO2/fluorine-doped tin oxide (ClO4--PEDOT/TiO2/FTO) conduction glass counter electrode (CE) is fabricated in dye-sensitized solar cells (DSSCs) by using a facile electrochemical deposition method. Compared to the ClO4--PEDOT/FTO CE, the photocurrent-voltage measurement reveals that the photocurrent conversion efficiency (eta), fill factor, and short-circuit current density (J(SC)) of DSSCs with a ClO4--PEDOT/TiO2/FTO CE increase. Electrochemical impedance spectra indicate that the charge-transfer resistance on the ClO4--PEDOT/electrolyte interface decreases. Cyclic voltammetry results also indicate that the ClO4--PEDOT/TiO2/FTO electrode shows a higher activity toward I-3(-)/I- redox reaction than that of the ClO4--PEDOT/FTO electrode.
