In article number 1901966, Guichuan Xing, Yanlin Song, and co‐workers present a new low‐dimensional perovskite based on 1,4‐butanediamine (BEA), with the alternating ordered of diammonium and monoammonium cations in the interlayer space. Taking advantage of the short layer spacing and hydrogen bonding, a barrier‐free and balanced carrier‐transport pathway with an enhanced carrier‐diffusion mechanism is proposed. Due to the hydrophobicity of BEA, the new low‐dimensional perovskite exhibits excellent stability.
