Organic–inorganic halide perovskites have attracted enormous attention for future optoelectronic applications because of their remarkable optical and electrical properties, solution processability, low cost, and large-scale fabrication capabilities. In addition to their use in photovoltaics and light-emitting diodes, halide perovskites have recently emerged as promising candidates for new-generation photodetectors. However, conventional three-dimensional halide perovskite photodetectors suffer from current–voltage hysteresis, unreliable performance, and instability. By controlling the morphological dimensionality of bulk three-dimensional and quasi-two-dimensional structured perovskites, low-dimensional halide perovskites (LDHPs, such as two-dimensional, one-dimensional, and zero-dimensional halide perovskites), which have robust chemical stability and optoelectronic tunability owing to the quantum size effect, can be obtained, providing an alternative solution to overcoming the aforementioned limitations. In this Review, we examine the current state of the art and highlight the recent advances in photodetectors based on LDHPs, with a focus on their operation mechanisms, device architectures, synthesis and modification methods, and photodetection performances. We also discuss the current challenges for and provide a future perspective on the creation of LDHP-based photodetectors with unprecedented performance and opportunities for commercialization.

基于低维卤化物钙钛矿的新一代光电探测器

有机-无机卤化物钙钛矿因其卓越的光学和电学性能，溶液加工性，低成本和大规模制造能力而引起了未来光电应用的极大关注。除了在光伏和发光二极管中的用途外，卤化物钙钛矿最近已成为新一代光电探测器的有希望的候选者。但是，常规的三维卤化物钙钛矿光电探测器具有电流-电压磁滞，性能不稳定和不稳定的问题。通过控制块状三维和准二维结构钙钛矿，低维卤化物钙钛矿（LDHP，例如二维，一维和零维卤化物钙钛矿）的形态尺寸，可以获得由于量子尺寸效应而具有鲁棒的化学稳定性和光电可调性的化合物，从而提供了克服上述局限性的替代解决方案。在这篇综述中，我们将检查当前的技术水平，并重点介绍基于LDHP的光电探测器的最新进展，重点是其工作机制，设备架构，合成和修改方法以及光电探测性能。我们还将讨论基于LDHP的光电探测器的创建所面临的当前挑战，并提供未来的前景，该探测器具有前所未有的性能和商业化机会。我们检查了当前的技术水平，并重点介绍了基于LDHP的光电探测器的最新进展，重点是其工作机制，设备架构，合成和修改方法以及光电探测性能。我们还将讨论基于LDHP的光电探测器的创建所面临的当前挑战，并提供未来的前景，这些探测器具有空前的性能和商业化机会。我们检查了当前的技术水平，并重点介绍了基于LDHP的光电探测器的最新进展，重点是其工作机制，设备架构，合成和修改方法以及光电探测性能。我们还将讨论基于LDHP的光电探测器的创建所面临的当前挑战，并提供未来的前景，该探测器具有前所未有的性能和商业化机会。
