Abstract
Research on exploring new materials and structures and optimizing of integrated photosupercapacitors systems are extensively developed. In this work, we report the study of the influence of light intensity on the performance of photosupercapacitors. The photosupercapacitors was constructed from active materials TiO2-ZnO-natural dye-DSSC-and BaTiO3-PVDF based supercapacitors. In the DSSC section, we used TiO2-ZnO for their excellent photon absorbing and electron mobility efficiency. In supercapacitor section, was constructed using BaTiO3 high dielectric material and ionic porous flexible PVDF material. A flexible aluminum foil was implemented as a common contact electrode separated DSSC and Supercapacitor section. XRD, FTIR,and SEM were used to characterize the raw or composite materials. While the photoelectric current (Isc), and open current voltage (Voc) at various intensity was performed using photodetector. The photo charging on supercapacitor section was measured using LCR meter while impinging light intensity of 30400, 60800, 91200, 144500,and 170800 Lux. It is shown that intensity significantly influences the charging rate on supercapacitor section. The higher the intensity, the quicker the charging occurs.
