Electrodeposition of Cu(In x Ga (1-x) )Se 2 Thin Film

(CIGS) 박막은 다원화합물이기 때문에 제조공정이 매우 까다롭다. 진공장치를 사용하는 제조 방법으로 동시증착법, 스퍼터링법 + 셀렌화가 있고, 비진공 제조 방법으로 전기화학적인전착법이 있다. 각 방법에 있어서도 출발 물질의 종류에 따라 다양한 제조 방법이 동원 될 수 있다.진공증착에 의한 방법은 고품질의 박막을 얻는데 사용 되고 있으나 고가의 진공장비가 사용되므로대면적화에 따른 제조비용 측면에서 문제가 있다. 이에 비하여, 전착법은 간단하면서도 저가로대면적화를 이룰 수 있다는 장점 때문에, 많은 관심이 기울여지고 있다. 본 연구에서는 Mo/Glass전극위에 Ga/(In + Ga) = 0.3의 성분비를 만족시키는 CIGS 박막을 전기화학적으로 제조하기 위하여,Cu
