Abstract
n this work we report the structural, optical and electrical properties of CdS thin films prepared by chemical bath deposition (CBD) under the effect of solution temperatures. The XRD patterns show that the films have a hexagonal phase with a preferential (002) orientation. The structural parameters such as the grain size, dislocation density and strain are calculated for the films. The transmission spectra, recorded in the UV visible range reveal a high transmission coefficient (85%) in the obtained films. The optical gap values of 2-2, 4 eV are deduced from the UV-visible transmittance. The electrical characterizations show that the films deposited possess good optoelectronic properties.
