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