TL;DR: The second harmonic generation (SHG) properties of the hybrid organic/inorganic germanium perovskite compounds display remarkably strong, type I phase-matchable SHG response with high laser-induced damage thresholds (up to ∼3 GW/cm(2).

TL;DR: It is demonstrated that a drying-mediated self-assembly process can be used to create close-packed monolayer membranes that span holes tens of micrometers in diameter and that the membrane's elastic response is set by how tightly the ligands are bound to the particle cores and by the ligand-ligand interactions.

TL;DR: Molecular dynamics simulations suggest that a competition among the interactions between the nickel cation, water, and birnessite promote redox chemistry in the spatially confined interlayer region.

TL;DR: It is clearly demonstrated that singlet fission and its conjugate process, triplet-triplet annihilation, occur at a longer intermolecular distance than an excimer intermediate would impute, establishing that an endothermic singlet-fission material must be designed to avoid excimer formation, thus allowing singlets fission to reach its full potential in enhancing photovoltaic energy conversion.

TL;DR: In this article, the authors analyzed the shortcomings of previously reported devices and unfold a roadmap toward device-relevant, high-efficiency upconvertors, which should not be less than 0.1 mA cm−2 under 1 sun excitation conditions.
