ABSTRACT:
A method of producing semicrystalline silicon by heating the silicon to a molten state and gradually cooling the silicon to mitigate disruptions in the silicon continuum and promote semicrystalline growth. The product formed is a silicon body, which may be sliced into wafers having highly ordered grains of a mean diameter of at least about one mm.
