Photo-powered and photo-responsive energy production and storage devices are promising alternatives to meet the growing energy demand in modern society. Solar energy is a clean and sustainable light source for these devices. Bismuth-based materials with oxychloride dopants exhibit superior optoelectronic properties due to their layered structure and rapid electron-hole pair separation ability. The unique crystal structure and inherent electrochemical properties of Bi3O4Cl make it an intriguing candidate for energy storage applications. In this study, we investigated the electrochemical performance of Bi3O4Cl as a supercapacitor material, exposed to both direct solar radiation and solar simulator radiation. Electrochemical measurements were conducted in a three-electrode system using a 2 M KOH electrolyte solution. Cyclic Voltammetry (CV), Galvanostatic Charge-Discharge (GCD), and Electrochemical Impedance Spectroscopy (EIS) were performed. In the GCD measurements, the pure material exhibited an average capacitance of 259.6 F g(-1), while specific average capacitance values of 689 F g(-1) and 676 F g(-1) were observed with direct sunlight exposure and solar simulator exposure, respectively. This represents approximately 165 % and 160 % enhancement in capacitance compared to the pure material.
