Abstract
In this study, the dependences of the volt-ampere characteristics of solar cells on the concentration of carbon quantum dots in a functional coating based on polyvinyl butyral are considered. The purpose of this study is to investigate the effect of carbon quantum dots (CQD) obtained in the volume of a polyvinyl butyral film on the surface of silicon mono- and polycrystalline solar cells (SC) on changes in the parameters of the volt-ampere characteristics for various conditions of obtaining by pulling and pumping the solution. The solution of carbon quantum dots in xylene was provided by Finteca LLC, Moscow. The photoluminescence method based on the MDR-41 monochromator was used to obtain the luminescence spectra of the CQD confirming the particle size, the volt-ampere characteristics of solar cells were obtained on the SolarLab 20- UST complex before and after the application of functional coatings, giving a comparative analysis of the main parameters of solar cells. The coatings with inclusions of carbon quantum dots make it possible to increase the efficiency of silicon solar cells by 2–4 %. Thus, functional coatings based on polyvinyl butyral and carbon quantum dots are a promising analogue to other functional coatings for solar cells, for example, Si3N4, CaF2.
