Role of Water on the Rotational Dynamics of the Organic Methylammonium Cation: A First Principles Analysis [PDF]
Scientific Reports, 2019 AbstractUnderstanding the degradation mechanisms of lead-halide perovskites (CH3NH3PbI3) under exposure to liquid/aerosol water is an essential problem within the photovoltaic community. Herein we investigate both the static and the dynamic properties of the methylammonuim cation (MA) as it coordinates with invading water molecules (MA.(H2O)n, n = 1, 2,

Organic Cation Rotation and Immobilization in Pure and Mixed Methylammonium Lead-Halide Perovskites [PDF]
Journal of the American Chemical Society, 2017 Three-dimensional lead-halide perovskites have attracted a lot of attention due to their ability to combine solution processing with outstanding optoelectronic properties. Despite their soft ionic nature these materials demonstrate a surprisingly low level of electronic disorder resulting in sharp band edges and narrow distributions of the electronic ...
