Abstract
Highly stable selective absorptive coatings of copper oxides were deposited on commercially available galvanized iron substrates by a dip-and-dry technique. The optothermal, structural, and optical properties of these films were investigated. The deposition parameters for an optimum selective absorptive film were determined. A typical such coating gave solar absorptance (AM1) of 0.91 and thermal emittance (100°C) of 0.17. Up to 300°C, the film was adherent and stable, having a top layer of CuO and an under layer of CuO of varying composition (x =1 to 2). However, increasing the temperature beyond 400°C converted the film to CuO only.
