Hydrophilic Silica Thin Film Formed Using Dimethyl Silicone Oil and Ozone

Abstract:

In order to fabricate the SiO₂ thin film using dimethyl silicone oil and ozone on protective covering glass for solar panels, the hydrophilicity and the transmittance of the film was investigated. We fabricated the film at different temperatures of 150°C, 175°C, 200°C, 225°C and 250°C on the glass substrates. The hydrophilicity of the film fabricated at 150°C showed very good hydrophilicity (water contact angle: ~8°), and transmittance was improved compared to the non-coated glass.
