Molten and Solid Trialkylsulfonium Iodides and Their Polyiodides as Electrolytes in Dye-Sensitized Nanocrystalline Solar Cells
Potential new electrolytes for dye-sensitized nanocryst. solar cells (DNSCs) of Graetzel type based on trialkylsulfonium iodides were studied. Room temp. molten salts of (Et2MeS)I, (Bu2MeS)I, and (Bu2EtS)I, with iodine in low concns., revealed good conducting abilities. DNSCs using iodine-doped (Bu2MeS)I as electrolyte achieved an overall light-to-electricity conversion efficiency of 3.7% in simulated AM 1.5 solar light at a light intensity of 0.1 Sun. The effects from varying the temp. during the I/V measurements were studied, as well as the effects of 4-tert-butylpyridine treatment of the electrodes.
