Abstract: In the realm of optoelectronics, hybrid nanocomposites are promising materials with significant potential as photodetectors. In order to design hybrid nanocomposites with superior photoconduction capabilities, PANI was hybridized onto V 2 O 5 by the hydrothermal method. To examine V 2 O 5 's photodetection characteristics, four varying PANI content concentrations were investigated. A comprehensive comparison revealed that achieving the greatest photoresponse was the best way to estimate the ideal concentration of PANI intercalated into V 2 O 5 nanofibres. The high performance of optimized photodetectors was ascribed to various photoconductive pathways, effective carrier generation, faster transport, and lower carrier recombination. For the optimized 1:3, the photodetectors’ responsivity, estimated detectivity, and external quantum efficiency (EQE) were calculated as 0.34 A/W, 1.59 × 10 10 Jones, and 137.52%, respectively, for a visible illumination source at a bias voltage of 5 V. The excellent device performance associated with the synergistic effect of PANI results in improving current generation and transport mechanisms. The findings demonstrate a novel approach for synthesising of a surfactant or binder-free hybrid nanocomposite for practical photodetection applications.
