dc.description.abstractSolar panel often facing problem that reduce the energy produced especially when dust and soil covers the surface of the solar panel, thus blocking the light. Not only that, reflection that occured reducing the transmittance of light. Thus, to overcome these problems, multilayer coating of SiO2:ZnO:SiO2 has been fabricated using sol-gel method, via dipping process and utilised glass sheet as a core. In this study, the SiO2:ZnO:SiO2 coating was compared to the SiO2:ZnO coating in terms of their transmittance, absorption and hydrophobicity properties. The water contact angle was used to evaluate the hydrophobic properties, while the Ultraviolet-Visible Spectrometer was used to measure the transmittance and absorption. The triple layer coating initiated 90.2% on its average transmittance while the double layer coating had only 61.48%. The absorption peak revealed that SiO2:ZnO coating had 0.86 A while SiO2:ZnO:SiO2 coating was only 0.33 A. On the other hand, the water contact angle for both coatings were good. However, the SiO2:ZnO:SiO2 coating showed a higher water contact angle, 126° compared to the SiO2:ZnO coating, 82°. The higher contact angle the lesser the surface energy thus it allows the water droplet to maintain its shape longer. The result indicated that the multilayer coating of SiO2:ZnO:SiO2 was successfully fabricated with better properties than conventional coating.en_US
