Abstract

Dye-sensitized solar cells (DSSCs) are an environmentally friendly and inexpensive photovoltaic technology that shows great promise. This study combines natural dyes that can absorb light in various wavelength regions, such as a combination of lavender and peony dyes; safflower and butterfly pea dyes, to improve the effectiveness of DSSCs. This combination is expected to expand the range of light absorption and improve solar cell performance. The dyes were extracted from various plants and tested using UV-vis spectroscopy. Results showed that the butterfly pea-safflower and lavender-peony combinations had efficiencies of 0.124% and 0.041%, respectively, while apple blossom was only 0.0064%. The combination of natural dyes showed a relative efficiency increase of 5.2% over the baseline cell. These findings indicate that the use of natural dyes has significant potential to increase DSSC performance and become a sustainable solution for renewable energy development. The use of NaCl as an electrolyte in this study represents a preliminary demonstration; therefore, the reported efficiency cannot be directly compared with that of conventional DSSCs employing iodide/triiodide or cobalt redox couples.
