A primary completely flowed-through absorber in sandwich format is used to increase the degree of effect of a solar collector and beneath the absorber plate (1) is a parallel back plate (5). The hollow space between the absorber plate and the back plate can be completely flowed through over its total volume by a heat transport medium. Between the absorber plate and the back plate is a plate (3) in zigzag of corrugated format, which with the amplitudes of its profile contacts the absorber plate at the top and the back plate at the bottom. Alternatively, the plate is flat. Beneath the back plate at a short distance from it is a reflection mirror (6).
