Device for concentrating solar radiation in an absorber

A device (1) for concentrating solar radiation in an absorber (2), an anchoring frame (8) and an inflatable concentrator pad (3), which has a light-transmissive entry window (4) for coupling in the solar radiation and a reflector film (5) subdividing the concentrator pad (3) into at least two cavities (6, 7), wherein the reflector film (5) is designed to concentrate the solar radiation in the absorber (2) which is arranged in the cavity (6) of the concentrator pad (3), and with an anchoring frame (8), arranged outside of the concentrator pad (3), for anchoring the concentrator pad (3), wherein the absorber (2) is attached to the anchoring frame (8) by means of an absorber mount (15) and the concentrator pad (3) has at least one attachment opening (26) for the absorber mount (15) to pass through.
