The physical processes of optical reflection and transmission of a two-layer and three-layer nanocomposite film located on a silicon substrate in an external field of optical radiation are investigated. The optical transmission of two-layer and three-layer nanocomposite coatings was investigated taking into account the algorithm for optimizing the coating parameters. The energy coefficients of optical reflection and transmission of a two-layer and three-layer nanocomposite film on a silicon substrate are calculated depending on the wavelength of the radiation and the angle of incidence of the radiation at different latitudes of the solar panel. The numerical calculations of the energy Fresnel coefficients for antireflection three-layer nanocomposite coatings are performed. The performed numerical calculations of the optical parameters of three-layer nanocomposite films show that it is possible to increase the optical transmittance with certain geometrical parameters of the nanocomposite coating. As a result of numerical calculations, the optimal values of the optical parameters of three-layer anti-reflection nanocomposite coatings were found for the best fulfillment of the conditions of optical enlightenment of the underlying surface. It is shown that it is possible to increase the optical transmission of the interface with crystalline silicon due to the use of a nanocomposite structure with optimal parameters.
