Abstract

Development of new selective absorbers for high temperatures above 350-400°C and the application in solar farm and solar tower plants. Extensive theoretical work has been per-formed in order to examine the existing potential concerning the available materials and the possible coating methods. Concerning the materials new chemicals will be developed and their integration into high temperature photothermal stacks studied. The new materials include the rare earth metals, transition metals and the elements of the 8th group of the periodic system. The coating methods are chemical vapor deposition (CVD), techniques of catalysis, electroplating, heterogeneous reactions between a gas and a solid phase and topochemic reactions. The characterization of these selective absorber coatings will be carried out by measuring the thermal optical data (∝ , ∈)by X-ray examination, determination of the mechanical compatibility and chemical analysis.
