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.
