The sensitization of TiO_2 with a wide variety of dye has been investigated over the last 20 years for the development of efficient solar cells. The photovoltaic performance of many porphyrin-sensitized TiO_2 film is reported and compared to that in cells sensitized with a Ru (2,2'-bipyridyl-4,4'-dicarboxylate)_2 (NCS)_2 (N3) dye. In this paper, a novel photostable fluorinated porphyrin, 5-(4-carboxymethylsulfanyl-2,3,5,6-tetrafluoro-phenyl)-10,15,20- tris (pentafluorophenyl) porphyrin 1 was synthesized and characterized by ^1H-NMR. This porphyrin was investigated for conversion of light of solar sumilator into electricity by constructing a dye-sensitized solar cell using an I^-/I_3^- electrolyite. The 1-sensitized solar cell shows a short circuit photocurrent density of 2.56mA/cm^2, an open-circuit voltage of 0.37V, and a fill factor of 0.346. This corresponds to an overall conversion efficency of 0.33%.
