Impacts of PbI<sub>2</sub> on high-efficiency perovskite solar cells: exploring intercalation orientations and defects
Feifei Ren, Huiwen Xiang, Ke Zhao, Chengyan Liu
Abstract
The parallel and vertical intercalations of the layered PbI 2 in CsPbI 3 result in type-I and type-II band alignments, respectively. The deep-level states caused by certain defects in PbI 2 are not active recombination centers.
