Halide Perovskites: Suppressed Lattice Disorder for Large Emission Enhancement and Structural Robustness in Hybrid Lead Iodide Perovskite Discovered by High‐Pressure Isotope Effect (Adv. Funct. Mater. 9/2021)

In article number 2009131, Gang Liu and co-workers conduct high-pressure isotope research to discover a significantly suppressed lattice disorder realized by H/D substitution in hybrid halide perovskites, which reveals large emission enhancement and strong structural robustness in isotope-functionalized perovskite materials. The CD3ND3PbI3-based device also exhibits slower degradation of photovoltaic performance, which is promising for better materials-by-design and more stable photovoltaic applications.
