Paper Abstract

Cadmium telluride thin films were deposited on ITO, Mo and S.S. substrates by short circuiting the substrates to a cadmium foil immersed in a solution containing CdSO4 saturated with Te02. These films were characterized by x-ray diffraction, scanning electron microscopy and optical absorption measurements. Deposition was carried out by changing the bath temperature. The pH of the deposition bath was around 2. X-ray diffraction data indicate that the crystallinity improves with increase of bath temperature. Optical absorption measurements have yielded a direct bandgap value of 1.47 eV.
