THE EFFECT OF COADSORPTION ON PHOTOVOLTAI C PROPERTIES OF PORPHYRIN, PHTHALOCYANINE TIO2 ELECTRODE/

ZnTSPP/TiO2, GaTSPc/TiO2 and co-adsorbed ZnTSPP, GaTSPc/TiO2 electrode s have been prepared, The spectroscopic and photovoltaic properties of these electrodes have been studied, The results indicate that the ele ctrode co-adsorbed with porphyrin and phthalocyanine can not only expe nd the spectra of photo-current action, but also enhance the efficienc y of the incident-photon-current-conversion (IPCE), especially enhance the efficiency of IPCE of GaTSPc. This is because the aggregates of G aTSPc have no the;sensitization effect, and the aggregates of GaTSPc d ecrease by co-adsorption of porphyrin and phthalocyanine, so the sensi tization effect ability of phthalocyanine is increased signification.
