Self-Powered GaN Nanowire-Based Photoelectrochemical Type Photodetector for Wireless UV Photodetection in Seawater

We fabricated a wireless photo-detecting system consisting of a self-powered PEC PD based on GaN nanowires in an artificial seawater environment. The portable electrochemical workstation with wireless data transmission and cloud storage in this system shows a promising future in photo-detecting and optical communication applications.
