OPTICAL AND ELECTRICAL-PROPERTIES OF ORGANIC-INORGANIC COMPOSITE SYSTEM

Anionic phthalocyanine sodium hydrogallium 4,4',4 '',4'''-tetrasulfona ted phthalocyanine(GaTsPc) was used to modify the surface of a size-qu antized particulate TiO2 photoelectrode fabricated by electrostatic at traction. The photovoltaic features and interfacial electron transfer of the electrodes were studied by a photoelectrochemical method and su rface photovoltage spectroscopy. The results indicate that the light a bsorption of phthalocyanine monomer makes more contribution to the pho tovoltaic response in the TiO2/GaTsPc composite electrode in spite of obvious aggregation occurring in composite electrode.
