Integration Device of Super-Capacitors with Dye-Sensitized Solar Cells

This study aims to create a composite supercapacitor prepared by using carbon electrodes blended with wood-derived activated carbon and monolayer graphene. The supercapacitor was integrated into dye-sensitized solar cells (DSSCs) to form a comprehensive energy system. Such a system combines the functions of solar energy conversion and storage of solar power supply systems and wearable electronic devices. In this study, the impact of gel electrolytes was investigated on the performance and long-term stability of DSSCs and supercapacitors and the characteristics of the integrated energy system. The study results revealed that the DSSCs with gel electrolytes achieved a photovoltaic conversion efficiency of 6.19%, indicating the system's potential in light energy conversion. Additionally, by serially connecting multiple integrated components, we successfully powered LEDs, which demonstrated the system's feasibility in practical applications. The findings of this study expand the application of carbon materials in energy conversion and storage and offer new avenues for developing more efficient integrated energy systems. Future efforts further enhance the efficiency and stability of the system by optimizing material combinations and system structures, which allows for widespread applications.
