Abstract | Thin film sol-gel coatings on glass substrates for use in solar cells were studied. The precursor solution was made oftetraethoxyorthosilicate (TEOS 2.0-6.0% v/v) using hexadecyltrimethoxysilane (HDTMS 0.1-1.5% v/v) as hydrophobic modifierin the presence of NH4OH (0.05-1.0% v/v) as catalyst. Dip-coating was applied to glass and studied for the effects of solpreparation on water-contact angle, transmittance, and resistance to outdoor exposure of the coating. The results showed TEOS,HDTMS and NH4OH contents at 6.0, 1.0 and 1.0 vol.%, respectively, as optimal. Superhydrophobicity with a water-contactangle of 150.69o can be achieved with high transmittance and self-cleaning properties. The morphology and surface roughnesswere characterized by AFM and showed aggregates of silica particles in combination with the inherent microscale roughness ofglass. The stable voltage of solar cells having a coatings of this type (dip-coating in sol-gel with NH4OH catalyst) meets theindustrial requirements with potential for outdoor applications. |
