Dimensional Tuning in Lead‐Free Tin Halide Perovskite for Solar Cells (Adv. Energy Mater. 13/2023)

Quasi-2D Tin Perovskites As the most promising alternative to lead halide perovskite, tin halide perovskite suffers from the intrinsic Sn(II) instability. Incorporating large-sized organic cations forming quasi-2D structures increases the perovskite stability. For this reason, in article number 2204233, Guixiang Li, Mahmoud H. Aldamasy, Meng Li, and co-workers, discuss and evaluate the characteristics and challenges of quasi-2D tin perovskites, and propose potential research strategies for opening up new opportunities of lead-free tin-based perovskite photovoltaics.
