Electrochemical Investigation of Hydrogen Influence on GaSe–PbSe System

It has been investigated the electrochemical characteristics of gallium and lead selenides, depending on electrolyte type with and without the presence of solar irradiation. During the sunlight irradiation polarization takes place at the low values of current density and more positive value of potentials in comparison with the result obtained in darkness.Keywords: selenides of gallium, selenide of lead, difficult systems of semiconductos, electrochemical potential.
