Cadmium sulphide (CdS) thin films was deposited by chemical bath method onto glass substrate at room temperature. The absorbance spectra of the fabricated films were obtained with a Janway 6405 UV / Visible spectrophotometer in the wavelength range of 200nm - 1100nm. Structural and surface morphology of the films were carried out using an x-ray diffractometer with Cuk α radiation and Olumpus Optical microscope. Absorbance spectra of CdS thin film fabricated at varying concentration of ligand show very high absorbance in the UV region, moderate absorbance in the VIS region and relatively low absorbance in the NIR. There was no clear cut effect of the varying concentration of ligand on the absorbance of the deposited films.
