The optical properties; absorbance, transmission, reflection, absorption coefficient and energy band gap were carefully and solicitously studied using ultra violet visible spectrometer UV.vis. The vibration modes for the three samples were also determined and delimited using Fourier Transform Infra-red spectroscopy FTIR. The efficiency of dye sensitized solar cell DSSC was studied using and utilisation IV characteristic for three natural dyes&nbsp; (Beta Vulgarize, Curcuma Longa and Vulgaris var. cicla), where the cell was fabricated and processed by coating a conducting proceeding substrate of (FTO) using titanium dioxide TiO<sub>2</sub>.&nbsp; The power conversion efficiency was calculated and reckoned, which found to be [0.583, 0.539 and 0.285], respectively. The highest efficiency obtained from this DSSC sensitized by Beta Vulgarize which was 0.583%, and thus might be due to its concentrated, focussed dye and colour.&nbsp;</p> ER -
