Light‐Induced Bipolar Photoresponse with Amplified Photocurrents in an Electrolyte‐Assisted Bipolar p–n Junction (Adv. Mater. 28/2023)

Photoelectrodes A bipolar-junction photoelectrode based on a p–n-junction GaN nanowire array is shown by Haiding Sun and co-workers in article number 2300911 to exhibit unambiguously bipolar photoresponse with an output of positive negative photocurrents under illumination 365 nm 265 light, respectively. Importantly, dual-band optical communication system incorporated such constructed using only one decode dual-channel signals encrypted property.
