Structural and Optical Properties of CdxCr2-xS4 Thin Films Grown by Cbd Method for Solar Cell Applications
We report the structural and Optical properties of crystalline Cadmium Chromium sulfide (x= 0.6) thin films was deposited on glass substrate using the chemical bath deposition method. The prepared thin films were characterized by X-ray diffraction analysis; scanning electron microscopy. From UV spectroscopy, the value of fundamental absorption edge from the intercept lies between 1.5528 - 3.7083 eV and the corresponding α values were 6.869 × 105 to 1o.4129 × 105 cm-1. The direct optical energy band gap of this sample was 2.2735 eV lying in the range of semi-conducting materials, suitable for solar cell applications.
