Photoelectrochemical electrodes have been prepared by sequential deposition of quantum sized PbS, CdS and ZnS particles on TiO2 nanocrystalline films. Their photoelectrochemical properties have been studied in a two-electrode system which conforms more closely to practical conditions. The results show that the ternary sulfide PbS/CdS/ZnS co-sensitized TiO2 electrode generates incident photon-to-current conversion efficiency (IPCE) as high as nearly 100% under irradiation with 400 nm light; moreover its photostability is strongly improved, and this is the first report of this so far. The highest photoelectrical conversion efficiency is obtained for the TiO2/PbS/CdS/ZnS electrode, and is about twice as much as that of TiO2/PbS.
