Abstract

태양전지용 실리콘제조를 위한 acid leaching을 이용한 MG-Si중 불순물의 정련방법이 제공된다. 본 발명은, MG-Si 중 불순물을 정련하는 공정에 있어서, 산 용액에 부식저항성이 강한 pyrex beaker, carbon vessel, Al2O3 vessel, Tefron vessel 및 MgO vessel 중 선택된 하나의 용기를 마련하는 공정; 상기 용기에 MG-Si 실리콘에 부식성이 없는 HCl, HNO3, H2SO4, 및 HF 중 선택된 1종 이상의 산용액을 공급하는 공정; 상기 산 용액이 공급된 용기 내에 실리콘과 산용액의 중량비가 1:0.5~2를 만족하도록 MG-Si을 공급하는 공정; 및 상기 용기 내에서 MG-Si을 사전 설정된 온도와 시간 동안 유지함으로써 산용액과 Si과의 계면반응에 의한 Si중 불순물을 이온상태로 제거하는 공정;을 포함하는 acid leaching 공정을 이용한 MG-Si중 불순물의 정련방법에 관한 것이다.
