Abstract

현재 태양전지 시장의 80% 이상을 차지하는 결정질 실리콘 태양전지에서 전면전극(front-side metallization)은 태양전지의 효율과 제조단가에 크게 영향을 미치는 주요 인자이다. 태양전지의 발전단가를 낮추기 위해 결정질 실리콘 태양전지의 기술개발이 고효율화와 동시에 제조단가를 절감하는 방향으로 진행되는 추이에 따라 전면전극 제조기술에서도 소재 및 공정단가의 절감과 고성능 전극 형성을 위한 새로운 소재 및 공정 개발이 지속적으로 요구되고 있다. 본 논문에서는 현재 상용 결정질 실리콘 태양전지 제조에서 95% 이상으로 가장 널리 적용되고 있는 Ag 페이스트를 사용한 스크린 인쇄 전극을 중심으로 전면전극 제조기술의 현황 및 향후 전망에 대해 논하고자 한다.
