Methylammonium lead iodide perovskite (MAPbI<sub>3</sub>) exhibits long charge carrier lifetimes that are linked to its high efficiency in solar cells. Yet, the mechanisms governing these unusual carrier dynamics are not completely understood. A leading hypothesis-disproved in this work-is that a large, static bulk Rashba effect slows down carrier recombination. Here, using second harmonic generation rotational anisotropy measurements on MAPbI<sub>3</sub> crystals, we demonstrate that the bulk s ...[more]
