Nanometric multi-scale rough, transparent and anti-reflective ZnO superhydrophobic coatings on high temperature solar absorber surfaces
TL;DR: In this paper, a nanometric multi-scale rough, transparent and anti-reflective zinc oxide (ZnO) superhydrophobic coating on TiAlN/TiAlON/Si3N4 spectrally selective solar absorber surface was developed for solar thermal power generation applications.
