Abstract

Recently, thanks to their unique and attractive properties, such as tunable bandgap, high absorption coefficient, and long charge carrier diffusion length, metal halide perovskites have been recognized as one of the emerging candidates for next-generation optoelectronic devices. Optoelectronic devices based on perovskites have achieved significant breakthroughs in a relatively short period of time. However, their commercialization still faces various challenges, including stability, scalability, and reproducibility. Defects are often the culprits behind these problems, either inside the perovskites or at the device interfaces. Therefore, rational utilization of defect engineering to minimize the effect of defects on device performance and control of carrier behavior is the key to achieve efficient and stable perovskite-based optoelectronic devices (PODs). Given the important contribution to the rapid development of PODs, there is an urgent need to systematically investigate and summarize recent research advances in defect engineering. Therefore, in this review, defect physics in PODs are described in detail, the role and importance of defects in various PODs are highlighted, and various strategies for optimizing PODs are reviewed. Finally, based on the latest progresses and breakthroughs, the challenges facing in the future development of metal halide perovskites and their potential significance in the field of the optoelectronic are prospected.

金属卤化物钙钛矿光电器件缺陷工程
近年来,由于其独特而吸引人的特性,如可调谐的带隙、高吸收系数和长载流子扩散长度,金属卤化物钙钛矿已被公认为下一代光电器件的新兴候选材料之一。基于钙钛矿的光电器件在相对较短的时间内取得了重大突破。然而,它们的商业化仍然面临着各种挑战,包括稳定性、可扩展性和可再现性。缺陷通常是这些问题背后的罪魁祸首,要么在钙钛矿内部,要么在设备接口。因此,合理利用缺陷工程,最大限度地减少缺陷对器件性能的影响,控制载流子行为,是实现高效稳定的钙钛矿基光电器件(PODs)的关键。鉴于缺陷工程对其快速发展的重要贡献,迫切需要系统地调查和总结缺陷工程的最新研究进展。因此,本文将详细介绍pod中的缺陷物理特性,强调各种pod中缺陷的作用和重要性,并对优化pod的各种策略进行综述。最后,根据最新进展和突破,展望了金属卤化物钙钛矿未来发展面临的挑战及其在光电领域的潜在意义。
