Electrodeposition (ED) technique has been used to deposit thin film Cadmium Telluride (CdTe) on glass/fluorine-doped tin oxide (Glass/FTO) substrates using a two-electrode system from acidic, aqueous medium containing Cd(NO_3)_2 4H_2O, TeO_2 and CdF_2 as a dopant. Photoelectrochemical (PEC) cell measurement, X-ray diffraction (XRD), Optical absorption, and Atomic force microscopy (AFM) were carried out to study the electrical, structural, optical, compositional and morphological properties of the as-grown, heat treated and CdCl_2 treated ED-CdTe layers respectively. The characterisation data obtained signified 1370 mV as the best growth potential and CdCl_2 treatment at 400°C for 15 minutes as the best post growth treatment to achieve optimal result.
