Beschreibung
Zusammenfassung:	The present invention relates to a light absorbing device which comprises an transparent outer material layer, a space through which air is circulated and heated by light radiation passing through the outer the material layer, a radiation absorbing material layer, and an element which is adapted to divide the space in at least a first subspace, which comprises a first opening, and a second subspace, which comprises a second opening. The air is adapted to flow along a path having an extension from the first opening to the second opening. The path comprises flow resistance reducing means in at least one portion of the space which is adapted to reduce the flow resistance for the gaseous medium when it is guided through said portion of the space.
