Study of functional coatings of polyvinyl butyral with silver nanoparticles for photovoltaic converters

Abstract

Films of polyvinyl butyral with silver nanoparticles were obtained on the surface of solar cells. Spectral dependences of the external quantum yield of a solar cell at various concentrations of silver nanoparticles in a polyvinyl butyral film are presented. The largest increase in the external quantum yield of the solar cell (by 22,3%) in the spectral range 540-1040 nm was recorded at a concentration of silver nanoparticles in a film-forming solution of 7 mmol/L
