Effective antireflection coating based on TiO_2-SiO_2 mixture for solar cells

摘要

A mixed alloy of TiO_2 and SiO_2 has been obtained using a 3-kW solar furnace. Films of the TiO_2-SiO_2 alloy applied onto a surface of glass and silicon plates exhibit high strength and adhesion, are transparent in the spectral range of sensitivity of solar cells, and can be used as effective antireflection coatings. It is established that adding TiO_2 to SiO_2 improves the optical properties of oxide coatings.
