  • Hybrid organic-inorganic trihalide perovskites can make remarkable optoelectronic devices but their spin characteristics are less investigated. Here Wang et al. show spin-polarized carriers injection into methylammonium lead bromide films with long lifetime and realize spin LEDs and spin valves.
