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

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

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 ...

Reactively sputtered coatings on architectural glazing for coloured active solar thermal façades

Jean-Louis Scartezzini, Andreas Schueler, Martin Joly, Stefan Mertin, Virginie Hody-Le Caër

Covering a standard solar thermal collector with a coloured glazing, which is opaque to the human eye but highly transparent to solar energy, permits a perfect architectural integration of solar panels into glazed building façades. The colours are based on ...
