Zusammenfassung:According to the present embodiment, a solar cell has a tandem structure comprising a photoelectric conversion unit including a first photoelectric conversion unit including a photoelectric conversion layer made of a perovskite compound and a second photoelectric conversion unit including a semiconductor substrate. Here, in the second photoelectric conversion unit, a first semiconductor layer and a second semiconductor layer formed separately from the semiconductor substrate on one surface and the other surface of the semiconductor substrate may have different structures. 본 실시예에 따른 태양 전지는, 페로브스카이트 화합물로 구성되는 광전 변환층을 포함하는 제1 광전 변환부, 그리고 반도체 기판을 포함하는 제2 광전 변환부를 포함하는 광전 변환부를 포함하는 탠덤형 구조를 가질 수 있다. 여기서, 제2 광전 변환부에서 반도체 기판의 일면 및 타면에서 반도체 기판과 별개로 형성되는 제1 반도체층 및 제2 반도체층이 서로 다른 구조를 가질 수 있다.
