Ligand-Stabilized Reduced-Dimensionality Perovskites [PDF]

Journal of the American Chemical Society, 2016
Metal halide perovskites have rapidly advanced thin-film photovoltaic performance; as a result, the materials' observed instabilities urgently require a solution. Using density functional theory (DFT), we show that a low energy of formation, exacerbated in the presence of humidity, explains the propensity of perovskites to decompose back into their ...

Guanine‐Stabilized Formamidinium Lead Iodide Perovskites [PDF]

Angewandte Chemie International Edition, 2020
AbstractFormamidinium (FA) lead iodide perovskite materials feature promising photovoltaic performances and superior thermal stabilities. However, conversion of the perovskite α‐FAPbI3 phase to the thermodynamically stable yet photovoltaically inactive δ‐FAPbI3 phase compromises the photovoltaic performance.
