Abstract
Chiral halide perovskites (CHPs) represent a revolutionary material class, integrating the exceptional optoelectronic properties of halide perovskites with chirality. This unique combination enables advanced functionalities in chiroptics, spintronics, and next-generation optoelectronics. Recent breakthroughs highlight CHPs' capabilities in circularly polarized light (CPL) emission/detection, spin-selective charge transport, and nonlinear optical processes, establishing them as a focal point in multifunctional material research. This review provides an in-depth, device-centric analysis of the latest CHP technologies. Material design strategies, chirality induction/transfer mechanisms, scalable synthesis methods, and diverse device architectures are explored. Particular emphasis is placed on clarifying structure-property-performance relationships across applications, including CPL photodetectors, light-emitting diodes, lasers, second-harmonic generation devices, spintronic components, and neuromorphic optoelectronics. Additionally, CHPs' potential for cutting-edge applications such as multimodal polarimetry, artificial intelligence, and secure information processing is examined. By defining design guidelines and performance benchmarks, this review aims to bridge the gap between academic research and practical technology translation. It not only synthesizes the current state-of-the-art but also outlines future directions for high-performance CHP devices, driving progress in this rapidly evolving field.
