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

Abstract

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.
