光电探测器（PD）是指一种可以直接将光能转化为电流的能量收集装置。这种设备已广泛应用于从光电、生物医学、监视到环境监测等不同应用。它由各种陶瓷和混合材料制成的异质结组成。尤其是自供电PD由于其在基础科学、日常生活和商业价值方面的重要意义而引起了极大的关注。重要的是，自供电设备可以减少对外部电源的依赖，使其能够自我维持为智能设备供电。此外，由于光生电荷载流子分离、传输和提取的调节，自供电PD中的热光电子效应（PPE）可以使器件性能超出预期，因此非常有吸引力。这篇综述评估了PPE背后的基本机制，并讨论了各种纳米结构材料及其异质结的基础研究的最新进展。 PPE 在光电设备领域的研究实际上仍未得到充分研究。有必要向相关研究人员全面提供理论和实验概述。 PPE具有光响应性能优异、光响应速率快、暗电流极低、自供电PD开/关比大等优点。此外，铁光电子效应和压电光电子效应的协同作用可产生高效的自供电PD。在这里，我们讨论了自供电 PD 中个人防护装备未来发展的关键挑战和前景。这项全面的审查预计将为研究人员提供一条将个人防护装备与新结构和设备设计结合使用的精确途径，以增强未来的光电检测性能。
The Photodetector (PD) refers to an energy harvesting device that can directly convert light energy into electric current. Such a device has been widely used in different applications ranging from optoelectronics, and biomedical, surveillance to environmental monitoring. It consists of a heterojunction made up of various ceramic and hybrid materials. Especially, Self-powered PDs have attracted tremendous attention due to their significance in fundamental science, day-to-day life, and commercial value. Importantly, self-powered devices can reduce the dependency on an external power supply, making them self-sustainable for powering smart devices. Moreover, the pyro-phototronic effect (PPE) in self-powered PDs that boosts device performance beyond expectations is appealing thanks to the modulation of photo-generated charge carrier separations, transportation, and extraction.This review assesses the fundamental mechanism behind the PPE and discusses the recent progress of fundamental research in various nanostructured materials as well as their heterojunctions. The PPE remains virtually underexplored in optoelectronic devices. It is essential to comprehensively provide both theoretical and experimental overviews to the relevant researchers. The PPE has many merits such as excellent photoresponsivity, fast photo response rate, very low dark current, and a large light on/off ratio of self-powered PDs. Furthermore, the synergism of ferro- and piezo-phototronic effects gives rise to efficient self-powered PDs. Here, we discuss the critical challenges and perspectives for PPE in self-powered PDs for future developments. This comprehensive review is foreseen to offer researchers a precise path to employing PPE in conjunction with the new structure and device designs for enhancing photodetection performance in the future.
