| Zusammenfassung: | The present invention relates to an economical method for obtaining high-purity silicon from a solar cell recovered from a waste solar panel. The method comprises: a material preparation step (P100) of preparing the solar cells of the waste solar panel; a crushing step (P200) of crushing the solar cell prepared in the material preparation step to obtain a crushed cell; and a multi-stage acid leaching step of dissolving an impurity metal by adding acid to the crushed cell obtained in the crushing step.
본 발명은 폐태양광패널에서 회수된 태양전지로부터 고순도의 실리콘을 얻는 경제적 방법에 관한 것이다. 이 방법은; 폐태양광패널의 태양전지를 준비하는 소재준비단계(P100)와; 상기 소재준비단계에서 준비된 태양전지를 파쇄하여 파쇄전지를 얻는 파쇄단계(P200)와; 상기 파쇄단계에서 얻어진 파쇄전지에 산(acid)을 첨가하여 불순물금속을 용해하는 다단의 산침출단계;를 포함하여 구성된 것을 특징으로 한다. |
