Performance improvement of dye-sensitized solar cells by using natural chlorophyll and anthocyanin dyes

<span lang="EN-US">Natural dye-sensitized solar cells (DSSC) have gained so much attention in recent years due to its low-cost fabrication process, ease of fabrication, and environmentally friendly. In order improve the DSSC performance, absorbance spectral dyes must reach maximum visible spectrum values. The combination two with different spectra can be utilized expand spectral. Here, we demonstrated natural chlorophyll anthocyanin from cassava leaves black sticky rice, respectively, enhance performance. Our findings provide insights for increasing performance by varying dyes. highest efficiency was obtained Chlorophyll:Anthocyanin 3:1.</span>
