In article no. 1800299 , Liming Ding, Shangfeng Yang, and co‐workers apply Mg x Al‐NO 3 ‐LDH nanosheets as a novel cathode interfacial layer (CIL) in BHJ‐iPSC for the first time, leading to an obvious efficiency enhancement relative to that of devices based on the commonly used ZnO CIL. The efficiency enhancement primarily originates from the increased fill factor due to the improved interfacial contact between the ITO and active layer, facilitating the interfacial electron transport.
