Abstract

The photo-current conversion properties of the nanostructured ITO/TiO₂/RuL₂(SCN)₂: 2TBA and ITO/TiO₂/RuL₂(SCN)₂: 2TBA/P3MT (L＝2,2'-bipydine-4,4'-dicarboxylic acid) electrode were studied by the photocurrent action spectra, the photocurrent dependence of potential, cyclic voltammety and UV-Vis absorption spectra. The composite sensitization could avoid the back electron transfer and loss of electrons. The photo-current conversion efficiency of ITO/TiO₂/RuL₂(SCN)₂: 2TBA/P3MT was improved compared with that of ITO/TiO₂/RuL₂(SCN)₂: 2TBA.

Key words: composite sensitization, photoelectrochemistry, conducting polymer
