  • Bismuth ferrite is an important room temperature multiferroic material where magnetism and ferroelectricity are coupled. Here, the authors utilize a wet chemical synthesis method to create strained nanoporous bismuth ferrite with enhanced magnetoelectric coupling and elevated magnetic moments.

  • Metal halide perovskite solar cells have shown promising performance, but mainly on small-area devices and under laboratory conditions. Now, researchers have demonstrated the fabrication of large-area devices assembled and packaged into modules and reported on their operation outdoors.

  • Metal halide perovskites feature crystalline-like electronic band structures and liquid-like physical properties that allow chemical manipulation of the structure with low energy input. Here, the authors leverage the low formation energy of 2D metal halide perovskites to demonstrate films that reversibly switch between multiple colors using tunable quantum well thickness.

  • Minor variations in synthesis conditions can redirect crystallization pathways through different nonequilibrium intermediates. Here, the authors present a theoretical framework to predict which polymorphs appear during MnO2 precipitation, which is validated by in situ X-ray scattering of reaction progression.

  • The stability of halide perovskite solar cells, determined by film morphology, is paramount to their commercialization. Here, the authors introduce a high-temperature DMSO-free method that enables better control of the grain size, texturing, orientation and crystallinity to achieve improved device operational stability.

  • High-throughput computation is especially useful for materials screening where synthesis is challenging. Here, it is used to construct a stability map of ternary nitrides, allowing discovery of stable compounds and providing insight into principles that govern nitride stability.

  • While metal halide perovskite solar cells are extensively investigated in the lab their performance and degradation in real-world outdoor conditions are still poorly understood. Now, researchers propose a method to analyse field data to identify how and why the outdoor device performance changes over time.
