Abstract
The growing demand for sustainable renewable energy technologies has driven the development of Organic Solar Cells (OSCs) based on environmentally friendly materials. This study developed an OSC prototype using a semiconductor blend of TiO₂ and ZnO, natural dyes from a mixture of anthocyanin, chlorophyll, and carotene, an electrolyte derived from pineapple peel extract with added salt, and graphite pencil 2B as the electrode. The main objective of the study is to optimize the efficiency of the OSC by analyzing the effect of three types of solvents (distilled water, ethanol, and H₂O) on the performance of the natural dye. Testing was conducted in two phases: 2–3 days and 28 days after fabrication, with reapplication of the electrolyte in the latter phase. Characterization included measurements of open-circuit voltage (VOC), short-circuit current (ISC), maximum power point voltage and current (VMPP and IMPP), fill factor (FF), and overall cell efficiency. The best performance was obtained from sample 3, which used H₂O as the solvent and a mixed dye composition. After 28 days with electrolyte reapplication, the cell produced an output power (Pout) of 0.134 mW and achieved a conversion efficiency of 0.455%.
