PCT No. PCT/EP95/02465 Sec. 371 Date Mar. 17, 1997 Sec. 102(e) Date Mar. 17, 1997 PCT Filed Jun. 24, 1995 PCT Pub. No. WO96/00871 PCT Pub. Date Jan. 11, 1996The present invention relates to a device for obtaining heat and/or electrical energy from sunlight with at least one solar collector (2) having an absorber (4) and an energy concentrator (6) surrounding the absorber over its length and at least regions of its periphery and optically concentrating the sunlight on the absorber (4). The energy concentrator (6) has a prism arrangement (12) of transparent material at least at its peripheral region which will be illuminated by the sunlight in accordance with the sun's daily movements, with a plurality of axial adjacent prisms (14) running parallel to the absorber (4) and distributed around the periphery. All the prisms (14) are equal sided in cross section and their apexes (18) are directed towards the absorber (4).
