WP2 High-temperature mirrors for secondary concentrators

WP Leader: CIEMAT
Objectives:

  1. Design and set-up of a solar testing-bench for high-temperature mirrors at CIEMAT’s solar furnace
  2. Outdoor exposure under realistic conditions  and accelerated testing in laboratory
  3. Understanding degradation mechanisms by analysing tested samples
  4. Development of high-temperature secondary mirrors with protective top coatings: Optimization of high solar reflective sputter coating with either high power impulse magnetron sputtering (HIPIMS) or plasma-enhanced chemical vapor deposition (PECVD) top coatings with improved lifetime
