Fabrication of a Zinc Aluminum Oxide Nanowire Array Photoelectrode for a Solar Cell Using a High Vacuum Die Casting Technique

الملخص EN

Zinc aluminum alloy nanowire was fabricated by the vacuum die casting.

Zinc aluminum alloy was melted, injected into nanomold under a hydraulic pressure, and solidified as nanowire shape.

Nanomold was prepared by etching aluminum sheet with a purity of 99.7 wt.% in oxalic acid solution.

A nanochannel within nanomold had a pore diameter of 80 nm and a thickness of 40 μm.

Microstructure and characteristic analysis of the alumina nanomold and zinc-aluminum nanowire were performed by scanning electron microscope, X-ray diffraction analysis, and energy dispersive X-ray spectroscopy.

Zinc aluminum oxide nanowire array was produced using the thermal oxidation method and designed for the photoelectrode application.
