Abstract
Thin films of cadmium sulphide were deposited on glass substrates by the chemicalbath deposition method. The results of measurements on the spectral responseof photoconductivity, the optical absorption coefficient and the x-raydiffraction were used for the characterization of films. This study revealedthat CdS films have tensile strain along the hexagonal (002) planes. Thedependence of strain on the grain size is responsible for the variation ofenergy bandgap with the film thickness. Annealing in air, and at a temperaturegreater than 150 °C, relaxes the strain, reduces the extent of disorder ingrain boundaries, reduces the energy bandgap and improves themobility-lifetime product for photogenerated carriers.
