Photo supercapacitor, as an innovative and advanced technology in energy storage, utilizes photo sensitive materials to enable the storage and conversion of optical energy into electrical energy. With its outstanding capabilities, this technology plays a crucial role in sustainable development and enhancement of energy systems. In this research, the FTO surface was coated with polyaniline and tungsten disulfide through electrochemical deposition using cyclic voltammetry technique. Multiple electrochemical tests, including cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance, were performed on various samples in a three-electrode system, and for the optimized sample, tests were conducted in symmetric and asymmetric configurations in a two-electrode system, with their results eva‎luated.In the symmetric configuration, both electrodes were optimized samples, while in the asymmetric configuration, one electrode was the optimized sample and the other was graphite. The specific capacity of the optimized sample in dark conditions was 0.84 mF/cm² and 2.794 F/g, which is 16.8 times the capacity of pure polyaniline. Moreover, the optimized sample’s capacity in light conditions was 2.3 times (6.339 F/g) that of dark conditions. The symmetric configuration maintained 97.74% of its capacity in dark conditions and 58.26% in light conditions after 10,000 charge-discharge cycles. In contrast, the asymmetric configuration showed approximately a 30% capacity increase in dark conditions and maintained 59% of its capacity in light conditions during 10,000 cycles.
