Abstract

Dye-Sensitized Solar Cells (DSSC) are photovoltaic devices that contain a dye that acts as a solar light acceptor. The use of dyesensitized solar cells to solve increasing energy demand and environmental problems still results in low efficiency values. In this study, optimization of DSSC components was carried out to increase DSSC efficiency by varying the thickness of the titanium dioxide (TiO2) semiconductor photoanode layer, polyvinylidene fluoride (PVDF) trap electrolyte membrane, and polyvinylidene fluoride nanofiber (PVDF NF) to obtain the optimum thickness. Scanning Electron Microscope (SEM) results of membrane thickness variation and titanium dioxide (TiO2) semiconductor photoanode coating showed the formation of nanofiber fibers composed of three-dimensional, porous, and diameter networks connected to the PVDF NF membrane. The increase in density and decrease in pore size, along with an increase in thickness and cracking as the TiO2 photoanode semiconductor layer increases, affect the electron transport rate of the DSSC. The higher particle density level will inhibit the electron transport rate, so it can reduce the efficiency of DSSC. The optimum thickness of the TiO2 semiconductor layer and PVDF NF electrolyte membrane of 0.20 mm and 0.35 mm can produce values, voltage, fill factor current density, and electrical efficiency of 500 mV, 2.7 x 10−3 mA.cm−2, 1.80%, and 2.40%, respectively.

Abstract

Indonesia has an electrification rate exceeding 99% as of 2020, yet it faces increasing electricity demands amid declining fossil fuel availability. Solar energy, particularly through DSSC, presents a promising renewable alternative, benefiting from an abundant radiation potential of up to 120.000 TW. DSSC have garnered significant attention due to their thin design, high efficiency, ease of fabrication, and environmental friendliness. The DSSC module was designed using two FTO glass plates as electrodes, with an anode surface area of 3 cm2. The TiO2 photoanode was prepared using a casting knife technique and then sintered at 450°C for one hour. This was followed by sensitization with anthocyanin dye derived from the butterfly pea flower under acidic conditions for 24 hours to ensure the stability of the compound. The electrolyte system consisted of PVDF NF membranes soaked in the electrolyte    solution for one hour to prevent leakage, thus completing the FTO/TiO2/PVDF/C/FTO system. Performance optimization involved arranging 20 DSSC cells in a mixed series-parallel circuit configuration. Electrical parameters were measured using a multimeter under various lamp irradiation durations. The optimal efficiency was achieved with 5 hours of irradiation, resulting in 2.050 mV and 23.5 x 10-3 µA. When integrated into a battery system, the DSSC module demonstrated effective current storage stability over 6 hours, indicating strong potential for practical implementation in sustainable energy generation for real-world applications.
