CC-BY-NC-ND 4.0 . Tin-containing metal halide perovskites have enormous potential as photovoltaics, both in narrow band gap mixed tin–lead materials for all-perovskite tandems and for lead-free perovskites.
During the past decade, metal halide perovskites are widely studied in the field of optoelectronic materials due to their unique optical and electrical properties. Lead-based halide perovskite solar cells (PSCs), in particular, currently achieve a record efficiency of 25.5%, thus showing strong potential in industrial application.
The search for non-toxic and efficient lead-free perovskite materials has therefore received much attention recently 8, 9, 10. Among these candidates, tin-based perovskite was considered one of the most promising lead-free photovoltaic materials due to its low toxicity, suitable optical band gap and high charge-carrier mobility 11, 12, 13.
ACS Energy Letters (2022), 7 (10), 3197-3203 CODEN: AELCCP; ISSN: 2380-8195. (American Chemical Society) Controlling the crystn. of perovskite in a thin film is essential in making solar cells. Processing tin-based perovskite films from soln. is challenging because of the uncontrollable faster crystn. of tin than the most used lead perovskite.
