Abstract

Metal halide perovskite materials are considered as promising semiconducting materials for next-generation solar cells due to their unique electrical and optical properties. Intensive progress in perovskite solar cell yielded a certified power conversion efficiency over 24%. However, most of highly efficient perovskite solar cells required Pb-based perovskite materials, which is a critical obstacle for their commercialization, and development of Pb-free perovskite materials is one of recent urgent issues in this field. In this paper, we will introduce recent research progress on Pb-free perovskite solar cells.

금속 할로겐 페로브스카이트 (perovskite)는 우수한 전기적, 광학적 특성으로 인해 차세대 태양전지의 핵심 소재로 큰 주목을 받고 있다. 페로브스카이트 태양전지는 등장 이후 전례 없는 단기간 효율 향상을 보이며 현재 24% 이상의 인증된 광전 변환 효율을 달성하였지만, 대부분의 고성능 페로브스카이트 태양전지는 유독성 납 (Pb)을 기반으로 한 페로브스카이트를 사용한 것으로, 향후 상용화를 위해서는 납을 쓰지 않는 친환경 페로브스카이트 개발이 필수적이다. 본 글에서는 비납 페로브스카이트 물질 및 연구 동향에 대해서 소개하고자 한다.
