Abstract. The effect of bath temperature (60-90 °C) on structural, optical and electrical propertiesof CdS thin films deposited by chemical bath deposition (CBD) at a constant precursorconcentration and deposition time was studied. From the XRD analysis, it was found that thestructure of CdS thin fi lms varied with temperature. At lower temperature hexagonal structurewas dominated while at high temperature, the cubic structure was prominent. The band gap ofthe as-prepared CdS thin fi lms was calculated from the UV-Vis spectroscopic data, and it wasfound to be decreased with the increase of temperature. The resistivity of the CdS thin fi lms alsodecreased with the increase in temperature.
