Abstract
Solar cells using dyes as sensitizers continue to expand. Synthetic dye as sensitizing materials for synthesized solar cells have high production costs, are difficult to find, and can cause environmental pollution. Solar cells using photosynthetic pigments as cell sensitizers are a solution to this problem. In this research, we investigated the effect of photosynthetic pigment from the Navicula sp. TAD as a dye sensitized material on the efficiency of Dye Sensitized 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 carotenois with the content of 8.570 and 2.581 g/mL, respectively. Solar cells using pigment crude extract, which are absorbed by TiO2 as electrodes have efficiency values of 4.475 x 10^-4
