A Dye-Sensitized Solar Cell (DSSC) is a solar cell technology that converts solar radiation into electrical energy. Dyes play a pivotal role in DSSCs by absorbing sunlight and converting it into electrical energy. The development of natural dyes is driven by numerous negative impacts associated with the utilization of synthetic dyes. The objective of this study is to evaluate the performance of a combination of natural dyes from two sources under neutral and alkaline pH conditions. The performance parameters measured included Isc, Voc, and efficiency. The efficiency values obtained from the dyes (a), (b), and (c), respectively, were 2.02%, 2.55%, and 3.02% at neutral pH, and 1.92%, 2.73%, and 2.58% at base pH condition. Dye efficiency was higher in neutral pH conditions than in base pH conditions. The combination of dye (c) Clitoria ternatea/aquadest and Pandan leaf/methanol showed the best efficiency, reaching 3.02%. © 2026, Gadjah Mada University. All rights reserved.
