     In this contribution, we report some studies on cadmium sulphide CdS thin films grown on glass substrates by Chemical Bath Deposition (CBD) process. The effect of the single and multiple dips deposition processes by using novel chemical bath on the thickness of CdS obtained is investigated. In addition, the influence of the precursor concentrations on the optical transmission of as-deposited thin films is also studied. Optical spectrum, structural cristallinity and surface morphology of CdS thin films were also studied. The optimum deposited films were well adherent, transparent and uniformly covered the substrate. Results indicate that the transmittance properties of the as-grown are affected by the reagents concentration variation in the bath solution and in general, the corresponding results obtained are in good agreement with the chemical mechanism process reported in the literature.
