Sn-based perovskite solar cells (PSCs) have received extensive attention for photovoltaic applications. Nevertheless, the low crystallization quality of the film due to rapid crystallization results in high trap density of states, which is one of the main reasons for poor performance of Sn-based PSC devices. In this work, we developed a strategy for the formation of FASnI3 perovskites by introducing the addition of formamidine acetate (FAAc). Benefiting from the iodide-coordinated cation (FA+) and crystallization-regulated anion (AC
