ABSTRACT:
In this work, the band
structure and optical-related properties of CuIn0.5Ga0.5Se2 thin film are presented. The calculation is performed by the full-potential
linearized augmented plane wave (FPLAPW) method. The spin-orbit coupling is considered. The result for
the dielectric function is in good agreement with earlier experimental
measurements and simulations. Based on the complex dielectric function, the
dielectric constant, the absorption coefficient, the complex refractive index
and the reflectivity at normal incidence are explored. We found that they are
comparable with the earlier results.
