Unraveling the Impact of Halide Mixing on Perovskite Stability. [PDF]

J Am Chem Soc, 2019
Increasing the stability of perovskites is essential for their integration in commercial photovoltaic devices. Halide mixing is suggested as a powerful strategy toward stable perovskite materials. However, the stabilizing effect of the halides critically depends on their distribution in the mixed compound, a topic that is currently under intense debate.

Edge stabilization in reduced-dimensional perovskites [PDF]

Nature Communications, 2020
AbstractReduced-dimensional perovskites are attractive light-emitting materials due to their efficient luminescence, color purity, tunable bandgap, and structural diversity. A major limitation in perovskite light-emitting diodes is their limited operational stability.
