Abstract: We report on studies concerning the photoelectrochemical behavior of a processed film of PAni-DBSA blended with EPDM in a photoelectrochemical device constructed using poly(ethylene oxide-co-epichlorohydrin)/NaI-I2 as polymeric electrolyte and a platinum counter electrode. Under open-circuit conditions, the anodic photocurrent obtained was 1 μA cm-2. In this condition and at positive bias, PAni behaves as n-type semiconductor. However at negative bias, an inversion of photocurrent signal confirms the p-type behavior of the polymer. The photocurrent is not limited by redox couple diffusion up to 60 mWcm-2, after this point the transport time of ionic charge carriers is higher than the generation time of electronic charge carriers.
