Abstract

Regarding greenhouse gas reduction, BIPV (Building Integrated Photovoltaics) is an important technology that can generate its own power in urban buildings based on clean energy resources. In particular, the perovskite material is attracting attention as a BIPV solar cell because it can have various colors and transparency. However, it is not easy to increase both transparency and efficiency factors because solar cell transparency and efficiency are inversely related to each other. Therefore, in this paper, we propose a semi-transparent perovskite solar cell structure that can improve both transparency and efficiency, and evaluate the stability according to international standard.

온실 가스 감축과 관련하여 BIPV (Building Integrated Photovoltaics)는 청정 에너지 자원을 바탕으로 도심의 빌딩에서 자체적으로 전력을 생산할 수 있는 중요한 기술이다. 특히, 페로브스카이트 물질은 투명성을 지니고 있으며, 다양한 색상 구현이 가능하여 BIPV용 태양전지로 주목받고 있다. 그러나 태양전지의 투과도와 효율은 서로 반비례 관계에 있어 두 인자를 모두 높이는 것은 쉽지 않은 과제이다. 따라서 본 논문에서는 투과도와 효율을 모두 높일 수 있는 반투명 페로브스카이트 태양전지 구조를 제안하고, 이를 평가하였으며, 안정성 평가를 위해 국제표준에 따른 내구성 평가를 수행하였다.
