A free-standing metallic article, and method of making, is disclosed in which the metallic article is electroformed on an electrically conductive mandrel. The mandrel has an outer surface with a preformed pattern, wherein at least a portion of the metallic article is formed in the preformed pattern. The metallic article is separated from the electrically conductive mandrel, which forms a free-standing metallic article that may be coupled with the surface of a semiconductor material for a photovoltaic cell.
