1. A method for producing syngas by using solar radiation, in which a reactor of a receiver-reactor is periodically heated via an aperture provided therein for solar radiation using the solar radiation to an upper reduction temperature (TO) for a reduction process and subsequently cooled to a lower oxidation temperature (TU) for an oxidation process in the presence of an oxidation gas, comprising:
guiding sunlight through an absorption chamber onto an absorber configured as the reactor, which includes a reducible/oxidizable material; and
guiding a gas that absorbs black-body radiation of the absorber through the absorption chamber, wherein an absorption area is configured so that 80% or more of the black-body radiation of the absorber present on a path to the aperture is absorbed.
