Solar cells using dyes as sensitizers continue to expand. The synthetic dye used as a sensitizing material for solar cells has high production costs, difficult to find, and can cause environmental pollution. Photosynthetic pigments as sensitizers are considered to be the solution to this matter. In this research, we investigated the effect of photosynthetic pigments from the Navicula sp. TAD as a dye-sensitized material on the efficiency of dyesensitized solar cell. To obtain high biomass, the Navicula sp. TAD was cultivated in a modified medium. Navicula sp. TAD has photosynthetic pigments consisting of chlorophyll and carotenoid. Solar cells using a crude pigment extract with a concentration of 300 ppm absorbed by TiO2 as an electrode have efficiency values of 4.475×10-4%.
