“…The goal of creating antireflection films is to get the substrate that has one coated on it as close to the refractive index of the incident medium as possible without losing transmittance. Several materials have been used as ARCs such as MgF 2 , SiO 2 , TiO 2 , ZnO, Al 2 O 3 , ZnS and BaTiO 3 [8][9][10][11][12][13][14][15]. The anti-reflection and self-cleaning coatings films can be made by single layer [6,[16][17] or multilayers [7][8][9].…”

“…Additionally, these coatings are unable to achieve broad-spectrum reduction in reflectance across a wide range of incident angles. To overcome these limitations, the multilayer anti-reflection design holds greater promise because it eliminates the need for materials with a refractive index lower than glass [8,18]. Titanium dioxide (TiO 2 ) and Silicon dioxide (SiO 2 ) are the most commonly used materials for multilayer anti-reflection coatings because their higher transparent properties [9,19].…”

The optical loss due to reflection is a significant barrier to the quantum efficiency of solar cells. In this work, an antireflective coating based on multilayers of metal oxides (TiO2, SiO2, ZnO) was prepared with the spin coating method. The coatings' antireflective, hydrophobic, and photocatalytic properties were examined. Based on the requirements met by the refractive index, a methodical selection of material and thickness for each layer was made in order to achieve near-zero reflection. The performance of different coating systems was examined by evaluating the percentage transmittance in the visible light range (400 nm - 800 nm). The optical properties of the obtained samples were studied with regard to transmittance and reflectance. The surface wettability of antireflective coating films was assessed by measuring the Water Contact Angle (WCA). The photocatalytic characteristics were evaluated by analyzing of the degradation of 0.02 mM Methylene Blue (MB) solutions after sunlight exposure for varying durations at midday.
