Dye- sensitized solar cell (DSSC) is a third-generation solar cell that can utilize natural dyes from leaves extract to absorb sunlight and generate electricity. This study aimed to investigate the performance of DSSC utilizing the leaf extracts of cassava, guava, and mango as a natural dye in terms of UV-Vis absorption and energy output. The experimental method was applied wherein the researcher constructed three DSSCs, each treatment applied the same fabrication, and construction. The UV-Vis Spectrum peak value and UV absorption was obtained from UV-Vis Analysis. The multimeter was used to record each voltage to determine the energy output produced by the DSSCs and the commercial solar cell. One-way ANOVA Analysis was used to determine the significant difference in UV absorption of natural dyes. In getting the significant difference between the three treatments and control in pairwise comparison in terms of energy output, One-Way ANOVA Analysis and Post Hoc Tukey were utilized. Based on the data result, there was no significant difference in UV absorption among the three natural dyes. This signified that the same pigment content gave almost the same UV absorbance at common UV Spectrum peak value in wavelength. The DSSC with natural dyes produced a smaller amount of electrical energy compared to commercial solar cells. There was a significant difference in energy output between the three treatments and the control. DSSCs utilizing natural dyes proved to produce electrical energy even in smaller amounts.
