Imaging the Moisture-Induced Degradation Process of 2D Organolead Halide Perovskites.

ABSTRACT: Two-dimensional (2D) and quasi-2D Ruddlesden-Popper (RP) phase organolead halide perovskites are promising materials for both photovoltaic and optoelectronic devices. Although they are known to be more stable when exposed to moisture than their 3D counterpart, chemical degradation of these materials under moisture, which not only leads to a significant drop in device performance but also leads to lead leakage, yet remains one of the most serious hurdles for their practical applications. To gain insight into the degradation mechanism of 2D/quasi-2D perovskites under moisture conditions, the degradation pathway of 2D/quasi-2D (PEA)₂(MA) _n-1Pb_nI_3n+1 (PEA = C₆H₅C₂H₄NH₃ ⁺,
