Antireflection coatings for solar cells based on an alloy of a mixture of MgO and SiO2

Alloys of a mixture of MgO and SiO₂ oxides are obtained using radiant heating. X-ray phase analysis shows that the mixture alloys are multiphase crystalline structures and solid solutions; they contain a glass phase and traces of the original oxides. For the mole: mole concentration, forsterite is identified in the composition of the composite material. It is found that films of an alloy of MgO and SiO₂ deposited on the surface of glass and silicon wafers exhibit high mechanical strength and adhesion; they are transparent in the range of sensitivity of solar cells and can be used as antireflection coatings.
