Overview

Tower power plants represent the latest generation of solar thermal power generation systems (see figure). Large-area mirror arrays concentrate sunlight onto a central absorber, where it is converted into thermal energy, which is then transferred to a heat transfer medium. The challenge for further increasing the efficiency of solar power plants lies in developing materials with temperature stability up to 800 °C in air.
Within the framework of graduate theses and research projects, thermally stable coatings for the core components of solar tower power plants will be developed and tested. State-of-the-art in-situ and ex-situ methods such as magnetron sputtering, ellipsometry, UV-vis-NIR-FTIR retroreflector, and Raman spectroscopy will be employed.
