Methods and apparatuses for manufacturing cast silicon from seed crystals

摘要

Abstract Methods and apparatuses are provided for casting silicon for photovoltaic cells and other applications. With these methods, an ingot can be grown that is low in carbon and whose crystal growth is controlled to increase the cross-sectional area of seeded material during casting.
