Copper Black Coatings for the Absorption of Solar Concentration With an APPJ SiO2 Super-Hydrophobic Protection

Solar thermal energy can be captured on absorbent surfaces, but coatings tend to deteriorate, due changes in hue, shocks, or detachment of all layers. There is a great challenge reducing the deterioration because environmental factors such as corrosion, impact, and dust control, among others. The interact with incident solar radiation transforming it heat energy, selectivity allows low emissivity. In this work, three-layer system copper proposed. An anodized CuO black layer an high absorptance A protective was added extend lifetime use while preserving functional characteristics by using SiO2 deposited atmospheric pressure plasma jet (APPJ) hexamethyldisiloxane. selective aluminum physical vapor deposition (PVD). Thermal shocks were applied concentrated power Fresnel lens represent sudden temperature when weather changes.
