[0002] Polycrystalline silicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooled conditions, silicon atoms arrange themselves into many crystal nuclei in a diamond lattice. If these nuclei grow into grains with different crystal orientations, these grains combine to crystallize into polycrystalline silicon. Polycrystalline silicon is manufactured using a casting process (square silicon ingots) from polycrystalline silicon block materials.
