(a) lateral of the RP phase (BA2MA2Pb3I10, requiring 2.79 eV) and (b) lateral of DJ phase (BDAMA2Pb3I10, requiring 0.51 eV) two-dimensional halide perovskites. The distance between inorganic layers in the DJ phase (3.853 Å) is shorter than that of the RP phase. (7.244 Å) since the DJ phase perovskite has no van der Waals gap between inorganic layers.
