The main objective of the project is the development of new types of slab metal solar absorber, which suppresses the fundamental drawbacks of the existing solar absorbers. It is characterized by heat transfer by entire surface to the heat transfer medium of the absorber and its thermal efficiency will be little dependent on the angle of incidence of solar radiation. This requirement will be solved by appropriate geometric structuring of the surface of the solar absorber. Another objective is a simple manufacturing technology of solar absorber using progressive production methods.
