Abstract: (4389 Views)
Selective solar absorber coatings of copper oxide (CuO) on stainless steel substrate are prepared by spray pyrolysis method. Effect of deposition temperature on optical properties of thin films investigated. Optical parameters, absorptance (α) and emittance (ε) were evaluated from reflectance data. It can be deduced that the porous structure like as a light trap can greatly enhance absorbance ,while the composition ,thickness and roughness of thin films can greatly influence the emissivity. XRD study indicated the single phase nature and high crystallinity of the prepared CuO nanostructures. Solar absorptance are found to be in the range of 85-92%.
