All-solid state dye sensitized solar cells were fabricated using in situ photo-electrochemically polymerized poly(3,4-ethylenedioxythiophene) (PEDOT) as a hole transport phase. Absorbance spectra and photovoltaic performance of these solid cells revealed that PEDOT is more favorable than polypyrrole as a hole transport phase in terms of transparency and charge transport property. The solid cell using this PEDOT exhibited good linearity between light intensity and photocurrent density and the overall conversion efficiency of 0.53% at AM 1.5 illumination (100 mW cm(-2)).
