THE MICROSTRUCTURE OF POLYMER FUNCTIONAL COATINGS WITH SILVER NANOPARTICLES FOR SOLAR CELLS

Abstract

Within the framework of this study, functional polymer coatings with silver nanoparticles were obtained on the surface of silicon solar cells. The size of the nanoparticles used to create the coatings was ~100 nm. For the first time, the microstructure of the obtained coatings was investigated by scanning electron microscopy. It was shown that nanoparticles have a sufficiently high and uniform distribution density in the coating. In the coatings obtained using the drying method, that there are single defects in the form of the absence of a film. These defects are presumably due to differences in microrelief on the surface of solar cells and can be eliminated by reapplying the film. Experimental studies of the quantum yield of photoconverters have shown that functional coatings based on polymers with silver nanoparticles can significantly improve the characteristics of silicon solar cells.
