Suppression of Stacking Faults for Stable Formamidinium‐Rich Perovskite Absorbers
Advanced Materials, Volume 37, Issue 26, July 3, 2025.The authors show that the (011)C perovskite planes are prone to stacking faults formation in all leading formamidinium‐rich perovskite compositions. Using ethylene thiourea as a precursor additive, Othman et al. suppress those vulnerable facets, significantly enhancing the absorber's intrinsic stability under various operational conditions.

Locking in Color: Stable RGB Perovskite Nanocrystal Films via UV Cross‐Linking
Advanced Optical Materials, Volume 13, Issue 16, June 6, 2025.Combining block copolymer stabilized lead halide nanocrystals with a UV light‐based cross‐linking procedure yields ultra‐stable nanocrystal thin films, which are resistant to dissolution by organic solvents and impervious to interlayer ion exchange. This allows for the fabrication of stacked layer RGB all‐perovskite white light‐emitting phosphors with ...
