This study investigates the viability of anthocyanin pigments extracted from dragon fruit and mangosteen peel as natural sensitizers for dye-sensitized solar cells (DSSCs). The research compares two extraction methods; ethanol and deionized (DI) water and evaluates their impact on DSSC performance. Ethanol extracts exhibited higher absorbance and intensity, indicating the presence of vibrant pigments, anthocyanin. Ethanol extracts of dragon fruit demonstrate the best overall performance, achieving a remarkable conversion efficiency of 0.63%. The study highlights the influence of extraction solvent, fruit source, and dye characteristics on DSSC performance. The ethanol extraction method emerges as more effective in harnessing anthocyanin pigments for enhanced light harvesting and charge generation in solar cells. The findings contribute to the understanding of natural dye sensitizers’ viability in renewable energy applications. Further optimization and research can unlock the full potential of anthocyanin pigments, offering a sustainable and efficient alternative for future solar cell technologies.

摘要

This study investigates the viability of anthocyanin pigments extracted from dragon fruit and mangosteen peel as natural sensitizers for dye-sensitized solar cells (DSSCs). The research compares two extraction methods; ethanol and deionized (DI) water and evaluates their impact on DSSC performance. Ethanol extracts exhibited higher absorbance and intensity, indicating the presence of vibrant pigments, anthocyanin. Ethanol extracts of dragon fruit demonstrate the best overall performance, achieving a remarkable conversion efficiency of 0.63%. The study highlights the influence of extraction solvent, fruit source, and dye characteristics on DSSC performance. The ethanol extraction method emerges as more effective in harnessing anthocyanin pigments for enhanced light harvesting and charge generation in solar cells. The findings contribute to the understanding of natural dye sensitizers’ viability in renewable energy applications. Further optimization and research can unlock the full potential of anthocyanin pigments, offering a sustainable and efficient alternative for future solar cell technologies.
