| dc.description.abstract | Cd₁₋ₓZnₓS thin films prepared by a chemical bath deposition (CBD) method. Cadmium acetate, zinc acetate and thiourea used as a cadmium, zinc and sulfur ions in solution, respectively. Five types of samples were synthesized onto glass substrates with different Cd2+ and Zn2+ sources moralities in alkaline solution (pH=11) and at temperature 80 ºC. The films' thickness was in the range (102-120) nm and most film's thickness decreases while Zn concentration in solution increased. The transmittance of films increased as Zn concentration increased. All films, however, have high transmittance of 65-85% in the wavelength region (500-900) nm, which is high enough for solar cell applications. The energy band gaps of Cd₁₋ₓZnₓS films calculated and their values were (2.24-3.7) eV. The values of the width of the tails of localized states in the forbidden gap of the films obtained form Urbach plots and varied in the range (0.025-0.11) eV. The optical constants such as, extinction coefficient, refractive index, real and imaginary parts of the dielectric constant are found. The dispersion energy Ed and a single-oscillator energy Eo measured from the single oscillator model below the absorption edge are used to calculate the moments of the optical spectra M-1 and M-3. | |
