The utilization of natural dyes from Chassalia curviflora (CCE), which were successfully extracted to provide bioactive chemicals for the development of dye-sensitized solar cells (DSSCs), is the main focus of this work. These CCEs efficiently absorb light and stop charge recombination in solar cells after being extracted using ethanol. The absorption properties of these natural dyes are discovered to be greatly influenced by the kind and concentration of CCE, with an absorption peak observed at 350 nm. The dyes’ improved adsorption properties on TiO2 are indicated by the presence of functional groups, bond stretching, and bending features, as confirmed by FTIR and UV–Visible spectroscopic investigations. In the DSSC design, these dyes have been effectively combined with an FTO substrate covered with TiO2, serving as a photoanode. The resultant solar cells, which comprise a graphite-based counter electrode, I−/I3− electrolyte, and photoanode, have a power conversion efficiency (PCE) of 0.49 %. The measurements for fill factor, Voc, and Jsc are 0.4761, 1.652 mA/cm2, and 0.52 V, in that order. The phytochemical components of the dye are shown to be crucial in trapping electrons and holes, hence reducing charge recombination and promoting enhanced charge transport towards the titanium dioxide transmission group finding is noteworthy. Furthermore, a dipping time analysis reveals that a 15-minute duration is optimal for achieving a 0.146 % photoelectric conversion efficiency in DSSCs utilizing CCE.
