Optical and structural analysis of sol-gel derived Cu-Co-Mn-Si oxides for black selective solar nanocomposite multilayered coatings

Aïcha Hessler-Wyser, Pierre Loesch, Martin Python, Andreas Schueler, Thomas Gascou, Yannik Antonetti, Olivia Valérie Charlotte Bouvard, Martin Joly, Marina Aymara González Lazo

In this paper, we report the preparation of the precursor solutions for the deposition of Cu-Co-Mn-Si oxides by a sot-gel method in order to produce black selective coatings for CSP receiver tubes. Their optical properties were investigated by means of spe ...
