The energy spectra of charge carriers in several models of the ordered solid solutions and virtual crystal model based on the ferroelectrics of Sn$_2$P$_2$S$_6$ type are calculated by the semiempirical pseudopotential method. It is shown that the band gap depends on the employed model of the solid solution.
