Spatially resolved investigation of the defect states in methylammonium lead iodide perovskite bicrystals

Abstract: Introducing a modal system approach for the analytical perovskite thin-film trap physics evaluation. Our study confirms existing models for trap formation in MAPI, substantiating different defect states in the grain boundary and bulk regions.

“…There were many attempts to stabilize perovskite devices, especially SC with carbon‐related materials such as graphene and CNT. [ 86–90 ] The simple structure of a PeLEC enables deposition of the electrode directly on top of the perovskite layer. This configuration is limited by the number of electrode materials, due to a chemical reaction between perovskite and conventional metal electrodes causing rapid degradation.…”
