Metal halide perovskite semiconductors (MHSs) are emerging as potential candidates for opto-spintronic applications due to their strong spin-orbit coupling, favorable light emission characteristics and highly tunable structural symmetry. Compared to the significant advancements in the optoelectronic applications of MHSs, the exploration and control of spin-related phenomena remain in their early stages. In this minireview, we provide an overview of the various spin effects observed both in achiral and chiral MHSs, emphasizing their potential for controlling interconversion between spin, charge and light. We specifically highlight the spin selective properties of chiral MHSs through the chirality-induced spin selectivity (CISS) phenomena, which enable innovative functionalities in devices such as spin-valves, spin-polarized light-emitting diodes, and polarized photodetectors. Furthermore, we discuss the prospects of MHSs as spintronic semiconductors and their future development in terms of material design, device architecture and stability.
金属卤化物钙钛矿半导体（MHSs）因其强大的自旋轨道耦合、良好的发光特性和高度可调的结构对称性，正成为光自旋电子应用的潜在候选材料。与MHSs在光电子应用方面取得的重大进展相比，自旋相关现象的探索和控制仍处于早期阶段。在这篇综述中，我们概述了在手性和非手性MHSs中观察到的各种自旋效应，强调了它们在控制自旋、电荷和光之间相互转换方面的潜力。我们特别通过手性诱导自旋选择性（CISS）现象突出了手性MHSs的自旋选择性特性，这使得自旋阀、自旋极化发光二极管和偏振光电探测器等器件具有创新功能。此外，我们从材料设计、器件结构和稳定性方面讨论了MHSs作为自旋电子半导体的前景及其未来发展。
