Cadmium sulphide films have been grown by chemical bath deposition using an aqueous medium. Growth rate has been studied on the basis of the film thickness variation with deposition period. Structural investigation using XRD has shown the presence of polycrystalline deposits of wurtzite structure. The optical absorbance has revealed that the band gap of the CdS layers has been 2.39 eV. The CdS films have been employed in electrochemical photovoltaic cells of configuration glass/ITO/CdS//S
2S
2−
2//Ni to test their photoactivity. The solar cell parameters have been correlated with the growth parameters.
