Abstract

We have successfully fabricated the dye-sensitized solar cell (DSSC) devices using ruthenium complex dye, polymer electrolytes, and poly(ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT: PSS) as a counter electrode. The overall power conversion efficiencies of the devices using polyethylene oxide (PEO), polyethylene glycol (PEG), polymethylmethacrylate (PMMA), and polyvinyl acetate (PVAc) as polymer electrolytes were 4.08%, 3.87%, 0.49%, and 0.20%, respectively, while the efficiencies of DSSC devices using Pt counter electrodes showed similar values of 5.7 ± 0.1%. The differences in the efficiencies and the charge transfer resistances (R CT ) of the DSSCs with various polymer electrolytes and counter electrodes were measured by using an electrochemical impedance analyzer (EIS) and are discussed.
