| Abstract | 1,4-butanediamine(BEA) is incorporated into FASnI3(FA=formamidinium) to develop a series of lead-free low-dimensional Dion–Jacobson-phaseperovskites, (BEA)FAn@1SnnI3n+1. The broadness of the (BEA)FA2Sn3I10 band gap appears to be influenced by the structural distortion owing to high symmetry. The introduction of BEA ligand stabilizes the low-dimensional perovskite structure(formationenergyca. 106jmol@1), which inhibits the oxidation of Sn2+. The compact(BEA)FA2Sn3I10 dominated film enables a weak-ened carrier localization mechanism with a chargetransfertime of only 0.36ps among the quantum wells,resulting in a carrier diffusion length over 450 nm for electronsand 340 nm for holes,respectively.Solar cell fabrication with(BEA)-FA2Sn3I10 delivers a power conversion efficiency(PCE) of 6.43% with negligible hysteresis.The devices can retain over 90% of their initial PCE after 1000h without encapsulation under N2 environment. |
