This study presents the fabrication of organic UV–vis–NIR photodetectors based on poly(3,4‐ethylenedioxythiophene) (PEDOT) thin films synthesized via a plasma‐enhanced chemical vapor deposition at 10, 20, and 30 W plasma power. The effects power polymerization, as well optical, structural, morphological, optoelectronic properties, are analyzed using UV–vis, Fourier transform infrared spectroscopy, scanning electron microscope, microscopy–energy‐dispersive X‐ray. films, exhibiting bandgap 3.52–3.59 eV, uniformly coated Si surfaces. Photodiode photodetector performance is evaluated through current–voltage current–transient measurements under varying light intensities wavelengths. PEDOT 10 exhibit superior performance, with maximum responsivity detectivity 0.0975 A −1 1.65 × 1 0 cm Hz 0.5 900 nm, noise‐equivalent 5.38 − 2 / . Maximum external quantum efficiency recorded 23.975% 450 nm. These results emphasize suitability low‐power for applications due to their morphology characteristics.
