Abstract: Volumetric solar absorbers are designed to enable the penetration of radiation deep into the absorber in order to improve the efficiency of the energy transfer from incoming radiation to the ...

Abstract: A new volumetric (directly irradiated) solar absorber, nicknamed Porcupine , is presented. It was tested over several hundreds of hours at the Weizmann Institute’s Solar Furnace, using several ...

Abstract: A solar central receiver absorbs concentrated sunlight and transfers its energy to a working medium (gas, liquid or solid particles), either in a thermal or a thermochemical process. Various ...

Abstract: The Directly Irradiated Annular Pressurized Receiver (DIAPR) is a volumetric (directly-irradiated) windowed cavity receiver, designed for operation at a pressure of 10–30 bar, exit gas temperature ...
