Abstract: Due to the wide range of application prospects, the high-performance optoelectronic sensing system are crucial for supporting rapid societal progress. In this work, we propose and demonstrate an optoelectronic sensing system based on the on-board integration of a photodetector (PD) based on (In,Ga)N nanowires and an aqueous zinc-ion battery (AZIB) employing a polyaniline cathode successfully. The PD demonstrates distinct on-off switching characteristic under ultraviolet illumination and operates effectively in zero-bias (self-powered) mode. It can perform different logic gate operations, and its responsivity exhibits bias-dependent tunability. Furthermore, the AZIB demonstrates a coulombic efficiency of 99.55% at 1 mA cm −2 . Notably, by integrating the voltage supplied by the AZIB to the external circuit with the bias voltage regulation of the PD, the responsivity of the PD can be enhanced by 264%, demonstrating the beneficial role of the AZIB integration in optimizing detection performance. This study provides a novel approach to construct the safe, low-cost and portable photoelectric sensing systems, which is conducive to broadening application scenarios in the field of photoelectric technology.
