The aim of this study was to obtain a superhydrophobic coating by modifying anodized aluminum using polydimethylsiloxane (PDMS). In order to obtain a superhydrophobic coating on an aluminum substrate, a multistage treatment was implemented. Specimens of aluminum were treated by abrasive blasting, anodization in sulfuric acid, impregnation by PDMS, rinsing in toluene to remove excess of PDMS, and curing. A rough surface with an additional low free energy layer on it resulted in a superhydrophobic effect. The coating obtained has an average contact angle of 159°. The specimens were tested in terms of durability in natural conditions. Additionally, anti-icing and anti-fouling properties were evaluated. The coating was compared with anodized aluminum obtained by a basic process.

“…These coatings are typically very thin, with an optical thickness of about one-quarter to one-half the incident wavelength. The antireflector single-layer coating is only effective against reflection for a single wavelength, resulting in high-quality solar cells [38][39][40][41][42][43][44][45][46][47][48][49][50]. Precise PV modules optical assessment is not easy.…”

In this research, a detailed abacus adventure and statistic obsession are made to survey the relation of fractions of materials of the anti-reflective coating to effectiveness of a solar cell. Emphasis on the study of whether single or double-layer layers of coatings save energy reflection and improve absorption is done leading to energy conservation. The anti-reflective coating is a familiar term in the solar technology, as it is less realistic without the coating that minimizes the light reflection losses. By way of single or double coating, light transmission increased is by limiting reflection therefore making the surfaces of solar cells to receive more light improving efficiency. These finer details of the coating's power over the solar cells' light absorption depth and output effectiveness are thoughtfully and minutely deliberated. A great deal of numerical methods are used to model light and sunlight impinging on the coated solar cell environments. Light waves' behaviour, when meet an antireflection layer, is a very important aspect in explaining, to some extent, about the thickness of the layer and its materials composition. That is a great role, namely, statistical techniques in this study whose purpose is used to main performance gain in the solar cells. Through simulation and experimental data, correlations are established between solar cell performance and the coating’s parameters. The patterns found will be taken into consideration to further improve the coating. This research, not just performed steps by step analysis of reflection, absorption and power conversion features in solar cells coated; rather, guidelines to excellent anti-reflective coating were offered too. The clarification of complex connections between the performance of coating construction and solar cells performance is enabled in this research and its results significantly contribute towards the development of renewable energy engineering, hence giving the research a certain weight in the field of solar energy.

“…Such coating enhances the visibility of automobile windshield, glazing window, helps improve efficiency of solar cell, and oil‐water separation. While, multifunctional coating with both self‐cleaning behavior and high transparency has a wide variety of applications such as outdoor displays, windows of buildings, optical devices (Alam et al., 2021; Kim et al., 2019; Yu et al., 2013). The loss of light due to reflection can be minimized by fabricating a single layer coating with destructive interference.…”

Hydrophobic self‐cleaning surfaces exhibit low surface energy. The low surface interaction allows the water droplets to roll off easily. In this work, transparent hydrophobic coating was fabricated using precursors Polydimethylsiloxane (PDMS), Isobutyltriethoxysilane (iTES), and Pluronic F127 (PF‐127), as pore generator. PDMS/PF‐127 and iTES/PF‐127 composite films were fabricated by acid catalyzed sol gel technique. UV‐visible spectroscopy analysis revealed enhancement of optical transparency by 3% for PDMS/PF‐127 than iTES/PF‐127 composite surface. Transparency of PDMS/PF‐127 was maintained throughout visible region proving film stability. Porous nature was confirmed by Field Emission Scanning Electron Microscopy analysis. Water contact angle of 107° for PDMS/PF‐127 and 103° for iTES/PF‐127 was obtained. 3D laser profilometery analysis revealed PDMS/PF‐127 coated surface was rougher than iTES/PF‐127 composite film. Sand particles sprinkled on coated surface buckled upon contact with water, exhibiting self‐cleaning ability.
