Abstract—

The paper presents the results of measurements of coating reflection coefficients. These coatings are based on a mixture of germanium with germanium oxide deposited on a silicon surface. The volume concentration of Ge in GeO2 is 20 and 30%. The spectral reflection coefficient of the coating with a volume concentration of 20% has not changed for 11 years. The reflection coefficient of the coating with a concentration of 30% in the range of 400–600 nm has decreased by an average of 5%. The antireflective effect of both coatings is preserved. The coating based on a mixture of germanium and germanium oxide with a volume concentration of 20% is stable and can be recommended as an antireflection coating for solar cells.
