SYSTEM AND A METHOD FOR MANUFACTURING A HIGH PURE SILICON INGOT WITH A SOLAR CELL LEVEL BY REFINING A LOW PURE SILICON SCRAP, AND THE HIGH PURE SILICON INGOT MANUFACTURED BY THE SAME, IMPROVING PRODUCTIVITY WITH A CONTINUOUS CASTING TYPE

摘要

PURPOSE: A system and a method for manufacturing a high pure silicon ingot with a solar cell level and the high pure ingot manufactured by the same are provided to reduce a manufacturing cost by refining a low pure silicon scrap.;CONSTITUTION: A lower open crucible(B) is arranged in a vacuum chamber. The lower open crucible has a vertical axis. The lower open crucible is comprised of a heating crucible(10) and a lower cooling crucible(2). The lower open crucible is surrounded with an induction coil(1). A silicon scrap supply unit(C) supplies the low pure silicon scrap to the lower open crucible. A plasma arc heating source(D) is arranged in the vacuum chamber. The plasma arc heating source irradiates the plasma to the low pure silicon scrap supplied to the lower opened crucible. A reactive gas supply unit(E) is arranged in the vacuum chamber. The reactive gas supply unit supplies the reactive gas to a surface of a molten metal(5) from the low pure silicon scrap.;COPYRIGHT KIPO 2010
