Abstract
Poly(3,4-ethylenedioxythiophene) (PEDOT) is an excellent kind of conducting polymer, comparable to Pt in catalytic behavior in dye-sensitized solar cells. Electrochemical polymerization in the presence of different anions (doping ions) that work as counterions of the resulting oxidized state PEDOT has been carried out to verify the influence of doping ions on the photo-electron conversion performance in dye-sensitized solar cells. Electrochemical and photo-electrochemical measurements reveal that the interaction between polymer and substrate (FTO) directly influences the fill factor in I–V curves, especially in the PEDOT–PSS system.Keywords
