The aim of the study was to analyze the possibilities of increasing the density of optical radiation to improve the efficiency of concentrator solar photovoltaic systems. The possibility of increasing the efficiency of concentrator photovoltaic installations using optical media has been calculated and experimentally studied. It is shown that due to the use of optical media it is possible to reduce the area of the photocell by 1,5–1,7 times with the same power of the solar installation. The use of this approach seems to be an effective means of increasing the efficiency of solar concentrator systems of solar energy photoelectric conversion.
