제목 Novel cyclic sulfonium iodide containing siloxane high performance electrolyte for dye-sensitized solar cell
초록 A new type of solid and gel-state ionics based on siloxane cyclic sulfonium iodides was synthesized and used as electrolytes in dye-sensitized solar cells. The siloxane bis-cyclic sulfonium iodides (SiCSI1, 2) are shown light yellow with solid state, but siloxane mono- cyclic sulfonium iodide (SiCSI3) is brown color with gel state. The resulting electrolytes were characterized by 1H NMR, FT-IR, TGA and diffusion coefficient. The thermo oxidative stabilities of the prepared ones are lower than that of DMII because the bond strength of S+-C in thiophenium is lower than that of N+-C in imidazolium. Among the three SiCSIs based electrolytes, SiCSI3 showed a maximum photo-conversion efficiency of 7.3%. In addition, the performance of the DSSCs showed relatively reasonable compared with the imidazolium type DMII electrolyte.
