摘要：

CdS microcrystals were deposited on TiO2 and ZnO semiconductors and photoelectrochemical properties were studied from the viewpoint of semiconductor sensitization. The photocurrent of a CdS-TiO2 photoelectrode was caused by photoinduced electron transfer in the direction from CdS to TiO2. The photoelectrochemical properties of CdS-TiO2, such as a flat band potential, were found to be strongly influenced by those of CdS as sensitizer. The quantum yield of the photocurrent amounted to 30%. A photoelectrochemical solar cell composed of CdS-ZnO and polysulphide solution was studied.
