Abstract

본 발명은 태양전지의 전계발광 화상을 검사하여 태양전지 내부의 결함을 판정하는 방법 및 장치에 관한 것으로, 더욱 상세하게는 태양전지 셀 또는 모듈 양단에 소정의 주기를 갖는 교류 전력을 인가하고 태양전지에서 발생되는 전계발광 화상을 카메라로 검출하여 태양전지 내부의 결함 정보를 추출하고 품질을 판정하는 것을 특징으로 하는 태양전지 교류 전계발광 화상 방법 및 검사 장치에 관한 것이다. 본 발명은 태양전지의 내부결함을 판정하기 위한 전계발광 화상검사를 실현함에 있어서, 태양전지 셀 및 모듈의 미세균열, 접촉저항 및 내부저항, 열점 등 다양한 태양전지 내부결함 정보를 동시에 추출하고, 측정 시료의 가열 손상을 방지하여, 보다 안전하고 신속하며 정밀하게 검사할 수 있는 태양전지 교류 전계발광 화상검사 방법 및 장치를 제공하고자 하는 것이다.
