초록
태양전지 기판의 원료인 폴리실리콘의 공급부족은 태양광발전산업의 비약적인 발전에 있어 최대 걸림돌이 되고 있다. 태양전지 제조에 충분한 순도로 폴리실리콘을 값싸게 제조할 수 있게 하는 공정기술의 개발은 태양광발전의 가격 경쟁력과 활용범위를 크게 증가시키는 중요한 계기가 될 수 있다. 본 총설에서는 태양전지용 폴리실리콘 제조를 위해 현재 이용 가능한 기술들을 정리해보고, 최근에 주목받고 있는 유동층 석출공정기술과 관련하여 응용범위 확대를 가로막고 있는 주요 기술적 장애요인에 대하여 중점적으로 소개하고자 한다.
Recent rapid progress in the photovoltaic industry has seriously been retarded by limited supply of polysilicon used as the feedstock for silicon wafer-based solar cells. It is thus believed that development of a competitive process for preparing polysilicon with the quality required for solar cells can greatly enhance the competitiveness and extent of the photovoltaic application. Technologies currently available for preparing the silicon feedstock are reviewed with the recent fluidized bed silicon deposition process being discussed in more details in terms of key technical barriers.
