The energy band structure of CuIn 1– x Ga x Se 2 solid solution is calculated in the center of the Brillouin zone by empirical pseudopotential method, using the model of average statistical substitution. The results of calculations are in good agreement with experimental data. An estimation of the acoustic deformation potential and temperature deviation coefficients of lattice parameters is also made.
