Despite the impressive efficiency of perovskite solar cells (PSCs), their operational stability
is still hindered by the thermodynamic instability of the hybrid organic–inorganic absorber …

Using compressive mechanical forces, such as pressure, to induce crystallographic phase
transitions and mesostructural changes while modulating material properties in …

While instability in aqueous environment has long impeded employment of metal halide
perovskites for heterogeneous photocatalysis, recent reports have shown that some …

Tin alloying is a promising strategy to reduce lead content in metal halide perovskites solar
cells and to modulate the perovskite band gap. Mixed tin–lead perovskites have shown …

Formamidinium lead triiodide (FAPbI3) currently holds the record conversion efficiency in
the single-junction perovskite solar cell. Iodine management is known to be essential to …

Self-trapping of excitons or of free charges associated with the formation of color centers is
typical of conventional halides. By analogy, lead halide perovskites could in principle show …

The role of dipolar motion of organic cations in the A-sites of halide perovskites has been
debated in an effort to understand why these materials possess such remarkable properties …

The origins of many unique properties of halide perovskite semiconductors can be traced to
charge–lattice interactions that lead to large polaron formation combined with their unusual …

The motion of organic cations and its possible correlation with excited-state photodynamics
are important to the fundamental understanding of the superior performances of two …

In this article, we report on advanced molecular dynamics simulations of the atomistic
DMASnBr 3–water interface, which, coupled with a grand-canonical formulation of …
