In this work, natural dyes were extracted from dried plant leaves of plant cream, apricot, figs, apples, sage, thyme, mint, Ziziphus jujuba, orange, shade tree, basil, berry, Mirabelle plum, Victoria plum, peach, mango, pomegranate, banana, guava, and fluoridation-treated plant. The extracts were used as photosensitizers for dye-sensitized solar cells (DSSCs). The cells were assembled using nanostructured TiO_2 films. The best performance was observed for the DSSC sensitized with Ziziphus jujuba with an efficiency of 1.077%. The impedance spectroscopy of 3 cells was carried out and the equivalent circuits were found.
