Over the past decade, lead halide perovskites (LHPs), an emerging class of organic-inorganic ionic-type semiconductors, have drawn worldwide attention, which injects vitality into next-generation optoelectronics. Facilely tunable bandgap is one of the fascinating features of LHPs, enabling them to be widely used in various nano/microscale applications. Notably, wide-bandgap (WBG) LHPs have been considered as promising alternatives to traditional WBG semiconductors owing to the merits of low-cost, solution processability, superior optoelectronic characteristics, and flexibility, which could improve the cost-effectiveness and expand the application scenarios of traditional WBG devices. Herein, we provide a comprehensive review on the up-to-date research progress of WBG LHPs and their optoelectronics in terms of material fundamentals, optoelectronic devices, and their practical applications. First, the features and shortcomings of WBG LHPs are introduced to objectively display their natural features. Then we separately depict three typical optoelectronic devices based on WBG LHPs, including solar cells, light emitting diodes, and photodetectors. Sequentially, the inspiring applications of these optoelectronic devices in integrated functional systems are elaborately demonstrated. At last, the remaining challenges and future promise of WBG LHPs in optoelectronic applications are discussed. This review highlights the significance of WGB LHPs for promoting the development of the next-generation optoelectronics industry.
在过去十年中，卤化铅钙钛矿（LHPs）作为一类新兴的有机-无机离子型半导体，已引起全球关注，为下一代光电子学注入了活力。易于调节的带隙是卤化铅钙钛矿的迷人特性之一，使其能够广泛应用于各种纳米/微米尺度的应用中。值得注意的是，宽带隙（WBG）卤化铅钙钛矿因其低成本、溶液可加工性、优异的光电特性和柔韧性等优点，被认为是传统宽带隙半导体的有前途的替代品，这可以提高传统宽带隙器件的成本效益并扩大其应用场景。在此，我们从材料基础、光电器件及其实际应用等方面，对宽带隙卤化铅钙钛矿及其光电子学的最新研究进展进行了全面综述。首先，介绍了宽带隙卤化铅钙钛矿的特性和缺点，以客观地展示其固有特性。然后，我们分别描述了基于宽带隙卤化铅钙钛矿的三种典型光电器件，包括太阳能电池、发光二极管和光电探测器。接着，详细展示了这些光电器件在集成功能系统中的鼓舞人心的应用。最后，讨论了宽带隙卤化铅钙钛矿在光电子应用中仍然存在的挑战和未来前景。本综述强调了宽带隙卤化铅钙钛矿对推动下一代光电子产业发展的重要性。
