A method of the production of polyvinyl butyral films with silver nanoparticles was developed. Properties of the resulting films as anti-reflecting coatings for silicon photovoltaic converters (photoconverters) were studied. The experiments were carried out on samples with and without Si3N4 coating. It was indicated that, at maximum concentration of silver nanoparticles (7 mmol/l), the increase in the external quantum efficiency in the spectral range from 500 to 1000 nm was more than 20 % for the samples without Si3N4 coating. In the case of the engineered functional coatings onto the photoconverters with Si3N4, the quantum efficiency increased on average by 10 % in the range from 400 to 1000 nm, and by 15–20 % in the range from 320 to 400 nm.
