摘要

Cadmium sulfide (CdS) window layers have been deposited on indium tin oxide (ITO)-coated glasssubstrates by electrodeposition using the galvanostatic method from non-aqueous solution containingcadmium chloride (CdC12), sulfur (S8) and ammonium chloride (NH4Cl) at bath temperature of 90 C.2 Good quality CdS-deposited films are obtained at a cathodic current of 0.25 mA/cm . Structural,morphological, optical characterizations and electrical investigations have been carried out todetermine the optimum CdCl2 concentration and without or with heat treatment for the best CdS thinfilm properties. The X-ray diffraction showed that CdS films are polycrystalline in nature, with singlehexagonal phase. Annealing the samples at 400 C under oxygen atmosphere for 30 min resulted in anenhancement in crystallinity. Uniform, compact, free pinholes, stoichiometric, adherent, high opticaltransmittance and low resistivity CdS film is obtained using concentration of 0.2 M CdCl2 in the bathdeposition and after heat treatment.
