Abstract: Economical method of sequential adsorption and reaction of ionic layers has been implemented to obtain the fluorescent coatings containing PbS quantum dots with adjustable dimensions and controllable optical properties. The PbS quantum dot manufacturing mode has been identified and it allows forming a photoluminescent coating with a stable face-centered cubic structure of galena, the minimized level of micro and macro-deformations on the surface of single-crystal silicon photovoltaic devices. It was shown that the resulting fluorescent coating is characterized by an intense absorption of light within the spectral range of 300-400 nm. It is experimentally proved that application of PbS quantum dots on the surface of industrial prototypes of single-crystal silicon photovoltaic devices made in China leads to an increase in their coefficient of performance by 0.3% by increasing the short circuit current density by 1 mA cm–2, which is caused by the expansion of the spectral photosensitivity range to shorter wavelengths end up to 300 nm.
