Nine different metal-iodide-contg. (R2R'S)I with addnl. iodine provided overall solar-to-elec. energy conversion efficiencies of over 2%, while used as electrolytes in DNSCs in simulated AM 1.5 solar light at the light intensity of 100 W m-2. The highest overall conversion efficiency, 3.1%, was achieved by using the electrolyte (Bu2MeS)I:AgI:I2 in the proportions (1:0.03:0.05). The effects from 4-tert-butylpyridine treatment of the electrodes were studied. The effects of metal-iodide doping were also studied with respect to speciation in the electrolytes and potential influence on electrochem. cond.dye sensitized nanocryst titania solar cell trialkylsulfonium iodide electrolyteiodide ionic liq molten salt electrolyte heterojunction solar cellmolten solid metal iodide doped trialkylsulfonium iodide polyiodide electrolytetext::journal::journal article::research article
