Claim Text:
1. A cushion-shaped concentrator for concentrating solar radiation in a plurality of absorbers, the cushion-shaped concentrator comprising: the plurality of absorbers, wherein the plurality of absorbers comprises a plurality of photovoltaic elements or a plurality of tubes flown through by a medium, a transparent membrane configured to face incoming solar radiation, wherein the plurality of absorbers is positioned adjacent to the transparent membrane, a reflector membrane which reflects the incident radiation in the direction of the plurality of absorbers, tension elements arranged between the transparent membrane and the reflector membrane, and constrictions on the reflector membrane produced by the tension elements, respectively, wherein the transparent membrane and the reflector membrane form an outer casing for a chamber filled with a gas at overpressure and the plurality of absorbers are arranged inside the chamber filled with the gas at overpressure, wherein said tension elements counteract the overpressure in the chamber, wherein said constrictions on the reflector membrane separate a plurality of distinct concavely curved sections of the reflector membrane from each other, and wherein one of the plurality of absorbers is provided for each of the distinct concavely curved sections of the reflector membrane.
