Abstract
Electromagnetic signal detection for applications such as astronomy, product quality monitoring, health, and necessitates systems that are very responsive and wavelength selective. High quantum efficiencies and high responsibility have been demonstrated in photodetectors based on Ge–Ga–Sb, primarily in the visible range. The photoelectric responses of new low-voltage, high-responsivity, solution-processed, flexible photodetectors for optoelectronic applications are examined for the first time. This is accomplished by using the melt-quenching procedure to synthesize Ge–Ga–Sb compound and putting it on a silica glass substrate using the spin coating method. The films were investigated in the context of an electrical photodetection sensor based on impedance. Excellent responsivity, particular detectivity, external quantum efficiency, and response time were all demonstrated by the produced device. The findings show that Ge–Ga–Sb has good optoelectronic capabilities and might be used in applications with low optical intensity.
