Abstract: Organic-inorganic halide perovskite materials have emerged as an excellent material for the optoelectronic applications because of their unique optical and electrical properties. However, the heavy metal character of lead is unfriendly to the environment, which restricts the commercial applications. Tin（Sn）-based perovskite materials are the promising candidates due to their low toxicity, broad absorption and higher mobility. Up to now, the highest power conversion efficiency（PCE） of Sn perovskite solar cells has exceeded 14%, which is much lower than lead-based perovskite devices. This review discusses the effects of component engineering of tin-based perovskite, the perovskite device structures and the additives on the performance and device stability of tin-based perovskite devices. Finally a summary and outlook of the development of perovskite solar cells are given at the end of the paper that provides helpful insights for the preparation of efficient and stable Sn-based perovskite solar cells.
