Patent Abstract

The method involves manufacturing a layer consisting of a product by using metallic and non-metallic reactants by a process accomplished above a limit temperature. A substrate e.g. polyimide foil (1), is coated with the metallic reactant and is introduced into a bath (6) of the non-metallic reactant, where the bath is heated to a temperature above the limit temperature. A doping material i.e. sodium, is added to the bath, where the metallic reactant is selected from copper, indium, tin, zinc and gallium. An element such as selenium, is provided in the bath.
