Copper Thin Film Deposited By PVD on Aluminum AA4015 Substrate for Thermal Solar Application

Abstract

The copper nanoparticles (CuNP) films have been deposited on Aluminum-4015 substrate by PVD technique. Structural of thin film layer achieved have been analyzed by X-ray diffraction (XRD). While the chemical composition percentage of the multilayers (Zn-Ni) combined with thin layer and substrate evaluated via ED-XRF, other characterization likes surface morphology have been investigated by using scanning electron microscopy (SEM), FESM and AFM. Optical properties especially thermal absorption was measured in the UV/Vis range. The effect of coating parameter like time coating resulting different thickness thin film (50,100 and 150) nm deposited on Aluminum substrate have been studied and the influence on optical properties. SEM analysis and AFM results show that prepared films were denser with nanosize grains between (26-54) nm. Also, XRD results show nano copper was the main chemical component in the films. The films prepared by this technique have better optical properties like good absorption ranged between (87%-97%). Decreasing the emittance and increase the absorption leads finally achieve a good selectivity coating using in the solar thermal application.

Fabrication and Wetting Characteristics of Copper Thin Film: An Active Layer for SPR-based Sensor Applications

“…This makes Cu-based SPR sensors more environmentally friendly and safer for various applications [22]. There are several techniques for depositing thin lms of Cu, including electrochemical deposition, physical vapor deposition (PVD), chemical vapor deposition and supercritical uid chemical deposition [23][24][25][26]. The sputtering technique, a subset of PVD, is the simplest technique for metal deposition.…”
