[en] Polymer composites based on (Cu_1-xAg_x)₇GeSe₅I solid solutions are produced. The electrical conductivity of the composites is measured by impedance spectroscopy in the frequency range from 20 Hz x10⁶Hz and in the temperature interval 292-38 K. The frequency dependences of the total electrical conductivity are obtained, the Nyquist plots are constructed, and their analysis is performed. The effect of Cu⁺→Ag⁺cationic substitution on the total electrical conductivity and the activation energy, as well as on the electronic and ionic components of the electrical conductivity of composites based on (Cu_1-xAg_x)₇GeSe₅I solid solutions is studied on the basis of compositional dependences.
