摘要

Ultraviolet (UV) communication is a promising security optical wirelesscommunication technology, and self-powered photodetectors as their opticalreceivers offer formidable evolution opportunities. However, insufficientlight harvesting and carrier separation of self-powered photodetectors hinderthem from achieving high-efficiency UV communication. Herein, a multieffectcoupling strategy is proposed to design an enhanced self-poweredAg NPs@ZnO nanowires/PEDOT:PSS (AZP) UV photodetector. Taking fulladvantage of the plasmonic and pyro-phototronic coupling effect, the endogenoussynergistic enhancement of UV light utilization and charge separationefficiency is realized without external field. The responsivity and detectivityof the AZP photodetector are significantly increased more than two and threetimes respectively, and the response time is less than 0.1 ms. Furthermore,a UV communication system is integrated based on the self-powered AZPphotodetector that conducts synchronous, accurate, and rapid wireless datatransmission. Notably, the integrated UV communication system presentinglarge communication bandwidth with 4800 baud exhibits desirable efficientinformation transmission potential. This work provides design strategies forthe advanced self-powered UV photodetector toward future energy-savingand high-efficiency optical wireless communication.
