| Abstract | ||
| The optical properties of 2(CdS)X(CuInS2)1-X (CCIS) thin film systems grown by chemical spray pyrolysis on glass slides were studied .The obtained results of X-ray diffraction (XRD) structure analysis were polycrystalline for all values of X= 0,0.1,……0.4 , and have many phases with new phase (CCIS) .The optical characteristics of the prepared thin films have been investigated by UV-VIS spectrophotometer in a wavelength ranging (300-1100) nm . The prepares films have a direct energy gap (Eg) its value varied between (1.4 - 1.8) eV depending on X value . The optical constants such as refractive index (n) ,extinction coefficient (k) ,real and imaginary dielectric constants (ε1&ε2) also discussed .It is found that the prepared films are promising in thin film solar cell. | ||
