Abstract

Dye-sensitized photo-electrochemical cells based on a solid poly-(3,4-(ethylenedioxy)pyrrole) (PEDOP) electron mediating matrix were assembled and photo-electrochemically characterized. The conductive polymer was directly grown on the sensitized TiO2 surface exploiting a photo-assisted electropolymerization promoted by a properly designed ruthenium dye bearing pyrrole functionalities. J –V characteristics and photoaction spectra indicated very low efficiencies mainly determined by an efficient recombination of photo-injected electrons with both PEDOP acceptor states and oxidized sensitizers.
