This structure could help to overcome some of the lingering problems that continue to dog conventional 3D perovskite materials. Moisture can quickly degrade conventional 3D perovskite solar cells ...

Uchida’s team used Hitachi technology, focused ion beam microscopy combined with transmission electron microscopy, to gain detailed information about the crystalline structure of new perovskite ...

By utilizing "lattice strain" of the perovskite film, they managed to incorporate Rb ions into the structure, which prevented the unwanted phase segregation. This novel approach not only ...
