ABSTRACT:
A method is provided for converting polycrystalline ribbon to macrocrystalline ribbon in which a molten zone is formed in and moved along the polycrystalline ribbon. Macrocrystalline material in ribbon shape is formed as the molten region passes and the molten material resolidifies. The molten zone is formed in the polycrystalline ribbon by impinging energy beams from two energy sources on the two major surfaces of the ribbon. The combined energy from the first and second energy sources is sufficient to melt the ribbon material and to form a molten zone extending through the thickness of the ribbon. The molten zone has an intersection with each of the major surfaces of the ribbon. The two energy sources are adjusted independently to control the area of the intersection of the molten zone with each surface so that the areas are non-identical.
