Großanlagen und Solare Materialien

Department Facilities and Solar Materials

The department operates the large facilities of DLR’s Solar Research and has the objective to provide service at a dedicated level both to internal (DLR) and external (industrial and research partners) customers. At the site Koeln-Porz currently the large facilities comprise the high flux solar furnace and the high flux solar simulator. These facilities can deliver highly concentrated optical radiation at irradiances up to several MW/m² and radiant powers above 10 kW. Additionally the department has the access to a research platform which has been installed at the half level of the tower of the solar thermal demonstration power tower at Jülich (STJ); it is designed to receive radiant power of up to 500 kW.

Besides the provision of highly concentrated optical radiation the department delivers customer consulting services to design experiments and special test arrangements, to carry out and to supervise experimental campaigns, to acquire and supply experimental and related meteorological data, as well as to support the evaluations. In addition to the services the department comprises research on materials employed in solar electricity, process heat and fuel generation.

Indusol - Industrialisation of ceramic solar absorbers
The objectives of the collaborative project INDUSOL are the development and testing of industrial manufacturing process for the production of volumetric solar absorbers made from silicon carbide ceramics. The scientists of the Institute of Solar Research work together with their colleges from the DLR Institute of Materials Research and with their industry partner Saint-Gobain Industriekeramik Rödental GmbH. more ...

Optical Measurement Systems and Special Experiments under Space Conditions

(5. June 2013)
At the Department Facilities and Solar Materials of the DLR Institute of Solar Research there is equipment to launch concentrated solar radiation and also the radiation of different artificial light sources into a vacuum chamber. Samples with a diameter of up to 0.5 meters can be irradiated under vacuum conditions. Moreover, it is possible to provide these experiments with a liquid-nitrogen cooling. In this way, space-like conditions can be achieved. more ...
