Thin Film of Nickel-Zinc Solar Absorber Deposited on Nanostructured Copper Substrate by Reactive Electron-Beam Evaporation

This article deals with the motivation for development of selective thin film on structured substrate in the field of upgrading solar energy conversion. Some observations on reactive PVD E-beam and structural and optical properties of nickel-zinc solar absorber obtained were briefly discussed. The thin film of nickel-zinc obtained shows optimum optical properties as far as maximum absorptance and minimum emittance, these results verified closed to the Planck black body and the ideal selective film. The nickel-zinc oxides from the thin film obtained allow exceptional stability and semiconductor properties, make practical applications feasible for future photovoltaics designs.
