Three are three main technologies to produce polysilicon. The ‘modified Siemens process’ is currently the dominant technology in China. Trichlorosilane (TCS) is produced using two readily available metallurgical-grade silicon (of 95-99% purity) and liquid chlorine. After being purified through distillation, the TCS is.
