FABRICATION OF SiO2-TiO2 ANTIREFLECTION THIN FILMS FOR APPLICATIONS IN SOLAR PANEL

Abstract

In this study, we report the results of the Ti-SiO₂ antireflection films for applications in solar panel glass. Ti-SiO₂ films were fabricated on the glass substrates by doctor-blade method combined with annealing process. The Ti-SiO₂ films achieved are a nanocomposite of SiO₂ and TiO₂ nanoparticles. The obtainted results indicate that the concentration of Ti strongly affects on optical and hydrophillic properties. With the variation of Ti concentration in the range of 7-27%, the transmittance of the Ti-SiO₂ coated glass was increased from 90.2% to 94.7%. The highest transmittance of Ti-SiO₂ antireflection film coated glass, 94.7% at the wavelength of 550 nm, was observed at Ti concentration of 7% and film thickness of ~ 100 nm. Ti-SiO₂ films are hydrophyllic and have  a contact angle in the range of 4.2 - 58.9°. The optical and hydrophillic properties indicate that the achieved Ti-SiO₂ films are very promissing for applications in the solar panel glasss.
