Evaluating the efficacy and performance of dye-sensitized solar cells using pigments extracted from inthanin leaves

Abstract

This research study demonstrates the importance of using plants that are grown nearby to extract dyes from pigments. This study involved the production of dye-sensitized solar cells (DSSC) utilizing pigments derived from inthanin leaves to generate electrical energy. The main goal was to evaluate the performance of various DSSCs. The DSSCs were manufactured with dimensions of 3 x 3 cm, and a spectrophotometer examination was performed to investigate the extraction of pigments within the wavelength range of 400-700 nm. The inthanin leaf pigments exhibited the highest level of absorbance in the wavelength intervals of 400-470 nm and 650-680 nm. The analysis of the electrical performance showed the following results for the DSSCs utilizing inthanin leaf pigments: a short-circuit current (I_sc) of 0.2970 mA, an open-circuit voltage (V_OC) of 0.5907 V, a maximum power (P_max) of 0.0013 mW, a maximum voltage (V_max) of 0.1191 V, a maximum current (I_max) of 0.0106 mA, a fill factor (FF) of 0.720%, and an efficiency (η) of 0.012%. The results indicate that dye-sensitized solar cells made from natural substances, such as inthanin leaves, are feasible for future manufacturing and application.
