The effect of the ratio of CdS and PbS components on the surface morphology, optical and photoelectric characteristics of films obtained by hydrochemical deposition has been studied. It is shown that, depending on the predominance of CdS or PbS in the film, the surface morphology changes significantly, which correlates with changes in the optical and photoelectric characteristics. An increase in the stability of photoelectric characteristics is demonstrated only by samples with a predominance of CdS. When PbS predominates, photoquenching and slow relaxation of the dark current after illumination are observed. Keywords: heterophase structures, limited solubility, optical and photoelectric characteristics, IR quenching.
