ABSTRACT:
The black radiator contains a doped, crystalline silicon member having a honeycombed surface and contains a controllable electrical heating mechanism with which the silicon member can be heated. The heating mechanism has a heating coil that is a doped silicon structure that is oppositely doped to the doping of the silicon member and to which a controllable voltage is applied. The manufacturing method provides that the silicon member having a honeycombed surface be manufactured from an n-silicon member by electrolytic etching.
