The origins of many unique properties of halide perovskite semiconductors can be traced to charge-lattice interactions that lead to large polaron formation combined with their unusual electronic structure of defects. However, the ability to understand and control the interplay of these electronic states with dynamic disorder arising from structural fluctuations of the metal halide framework is needed to guide continued development of new variants of these materials. In this Perspective, we examine the influence that dynamic disorder has on charge-lattice interactions in halide perovskite materials that lead to charge localization and large polaron formation. Furthermore, we describe how the interplay of material composition, structural dynamics, and large polaron formation influences radiative and nonradiative band-edge recombination. Insights about how to control this interplay may inform development of related metal halide semiconductors including 2D Ruddlesden-Popper, double perovskite, and nanocrystalline systems with tailored radiative and charge transport properties while avoiding toxic elements.
