Abstract

Metal halide perovskites have emerged as promising semiconductors for next-generation optoelectronics, particularly due to their solution processability and exceptional semiconductor properties. Over the past few decades, the performance of perovskite-based solar cells (PSCs) and light-emitting diodes (PeLEDs) has seen rapid improvements. However, the operational stability of these perovskite optoelectronic devices remains a significant challenge. One critical factor influencing both efficiency and stability is the choice of hole-transporting materials (HTMs). Recently, there has been a growing focus on cross-linkable HTMs as a means to enhance device stability. This review systematically summarizes the role of cross-linkable HTMs in PSCs and PeLEDs, emphasizing their material advantages, design principles, physical properties, and advancements in device performance. Special attention is given to the impact of cross-linkable HTMs on device interfaces and overall stability. We conclude by discussing the future challenges that must be addressed to further advance the application of cross-linkable HTMs in both PSCs and PeLEDs.

钙钛矿光电子用交联有机空穴传输材料的研究进展
金属卤化物钙钛矿已成为下一代光电子器件的有前途的半导体,特别是由于它们的溶液可加工性和卓越的半导体特性。在过去的几十年里,钙钛矿基太阳能电池(PSCs)和发光二极管(pled)的性能得到了迅速的提高。然而,这些钙钛矿光电器件的运行稳定性仍然是一个重大挑战。影响效率和稳定性的一个关键因素是空穴传输材料的选择。最近,人们越来越关注可交叉链接的html,将其作为增强设备稳定性的一种手段。本文系统总结了交联HTMs在PSCs和pled中的作用,强调了它们的材料优势、设计原理、物理性质和器件性能的进展。特别要注意的是可交叉链接的html对设备接口和整体稳定性的影响。最后,我们讨论了未来必须解决的挑战,以进一步推进交联htm在psc和pled中的应用。
