Abstract
The sol-gel method has been widely used to synthesize the $TiO_2$ for dye sensitized solar cells and has advantages of easily fabrication process, controlling the $TiO_2$ phase and getting transparent thin-film composed of the $TiO_2$. In this paper, we synthesized the crystalline $TiO_2$ by sol-gel method controlled by the quantity ratio of Nitric acid and Ammonium hydroxide additives. The best efficiency result was obtained by 0.05 M Ammonium hydroxide and that results of Voc, Jsc, FF, and efficiency were 0.68 V, 3.28 mA/$cm_2$, 58.14 and 5.21%, respectively.
