COLOURED RADIATION ENERGY CONVERTER, METHOD OF PRODUCING THE SAME AND ITS USE

摘要

The invention concerns a radiation energy converter in the form of a highly effective selective absorber for converting electromagnetic radiation into heat. According to the invention, the degree of reflection in the region of a specific wavelength is increased such that a desired additive colour effect is produced. At the same time, however, it is ensured that the degree of efficiency of energy recovery is sufficient to heat water for industrial or domestic use, for example. In this way, for the first time, the design of the absorber is placed before optimization of the efficiency thanks to a novel use of the highly selective absorbers developed very recently. The invention also concerns a method of producing the radiation energy converter and its use.
