Ultraviolet (UV) communication is a promising security optical wireless communication technology, and self-powered photodetectors as their optical receivers offer formidable evolution opportunities. However, insufficient light harvesting and carrier separation of self-powered photodetectors hinder them from achieving high-efficiency UV communication. Herein, a multi-effect coupling strategy is proposed to design an enhanced self-powered Ag NPs@ZnO nanowires/PEDOT:PSS (AZP) UV photodetector. Taking full advantage of the plasmonic and pyro-phototronic coupling effect, the endogenous synergistic enhancement of UV light utilization and charge separation efficiency is realized without external field. The responsivity and detectivity of the AZP photodetector are significantly increased more than two and three times respectively, and the response time is less than 0.1 ms. Furthermore, a UV communication system is integrated based on the self-powered AZP photodetector that conducts synchronous, accurate, and rapid wireless data transmission. Notably, the integrated UV communication system presenting large communication bandwidth with 4800 baud exhibits desirable efficient information transmission potential. This work provides design strategies for the advanced self-powered UV photodetector toward future energy-saving and high-efficiency optical wireless communication.

通过多效应耦合策略实现高效紫外通信的内源协同增强自供电光电探测器

紫外线（UV）通信是一种很有前途的安全光无线通信技术，而自供电光电探测器作为其光接收器提供了巨大的发展机会。然而，自供电光电探测器的光捕获和载流子分离不足阻碍了它们实现高效的紫外通信。在此，提出了一种多效应耦合策略来设计增强型自供电 Ag NPs@ZnO 纳米线/PEDOT:PSS (AZP) 紫外光电探测器。充分利用等离子体和热光电子耦合效应，在没有外场的情况下实现了紫外光利用率和电荷分离效率的内生协同增强。AZP光电探测器的响应度和探测度分别显着提高了两倍和三倍以上，响应时间小于0.1 ms。此外，还集成了基于自供电AZP光电探测器的紫外通信系统，可进行同步、准确、快速的无线数据传输。值得注意的是，具有 4800 波特的大通信带宽的集成紫外通信系统表现出理想的高效信息传输潜力。这项工作为先进的自供电紫外光电探测器提供了面向未来节能和高效光无线通信的设计策略。具有4800波特的大通信带宽的集成UV通信系统表现出理想的高效信息传输潜力。这项工作为先进的自供电紫外光电探测器提供了面向未来节能和高效光无线通信的设计策略。具有4800波特的大通信带宽的集成UV通信系统表现出理想的高效信息传输潜力。这项工作为先进的自供电紫外光电探测器提供了面向未来节能和高效光无线通信的设计策略。
