For preparing photoconductive CdS thin films, there are various methods-evaporation method, sputtering method and others-by which, however, sufficiently high-sensitive photoconductors can not be produced. A new method has been devised in which CdS thin films are made in a mixture of H2S and H2 gases in an open type furnace, whereby US films of sensitivity higher than by any other method and of considerably good characteristics concerning, for example, photocurrent vs. applied voltage and photocurrent vs. excitation intensity are obtained. Photo-sensitivity of samples made by this method is almost equal to that of a sintered US cell.
