The method for electrophoretic deposition of nanocluster coatings on receiving surface of silicon photoelectric converters (PEC) from a colloidal silver solution is proposed. It is noted that the resulting coatings have a surface plasmon resonance (SPR) effect. A relevant phenomenological model for assessing the effect of non-metallic impurities likely incorporated during coating application on the occurrence of the SPR is proposed. Calculations in the multy-physical COMSOL 5.5 medium shows that the plasmon resonance condition is performed in the wavelength region of 270–370 nm when impurities are absent. The presence of non-metallic impurities reduces the probability of SPR and makes it impossible at admixtures concentrations of about 0.1 at.%. The experiment showed full compliance with the calculations.
