Abstract
Description
도 2는 본 발명에 있어서 도 1에 의한 Cu 조성비율 범위를 기초로 하여 Cu의 조성비를 0.85로 고정하고 In을 Ga로 치환하여 Ga의 조성비를 증가시켜가며 기계화학적 방법으로 제조한 CIGS 조성분말의 X-선 회절분석 결과.
도 3은 본 발명에 있어서 1차 합성된 CIGS 분말에 CuGaSe2 조성을 만족하는 Cu, Ga 및 Se 소스 분말을 추가하여 다시 기계화학적 밀링하는 2차 및 3차 합성단계를 수행하여 각 합성단계로 합성된 각 CIGS 분말조성의 X-선 회절분석 결과.
도 4는 본 발명에서 합성된 Cu0 .85In0 .70Ga0 .3Se1 .85 분말의 전자현미경사진(SEM) 및 EDX 결과.
