| Abstract: | The band gap and energy level of surface states of TiO-2 casting film and the energy level of ground state, energy level gap(HOMO-LUMO) and energy level of dual polarons of phenylcapped aniline tetramer(PAT) were investigated by means of surface photovoltage spectroscopy(SPS), cyclic voltammograms with irradiation(CAGI) and the photocurrent action spectra(PAS). Based on the experimental results the energy band structures of PAT/TiO-2/ITO thin film electrode are determined and the photo-to-electric conversion of PAT/TiO-2/ITO thin film electrode and the possible mechanism for interfacial electron transfer in PAT/TiO-2/ITO thin film electrode are discussed. |
