Sn-based perovskite solar cells (PSCs) are non-toxic solar cells and have attracted much attention to replace lead-based PSCs. While Pb-based quasi-two-dimensional (q-2D) perovskites are well-researched, the structure and stability of Sn-based q-2D perovskites have not been determined yet. In this study, with the aim of clarifying the influence of organic cations on structure of q-2D Sn-based perovskites, (A)2BSn2I7 (A= CH3(CH2)3NH3+; B= CH3NH3+, CH(NH2)2+, Cs+) were fabricated, structure and optical properties of perovskites were investigated.
