A power conversion efficiency of more than 7.2 % under AM 1.5 sunlight (100 mW cm −2 ) is reported for the first time for an organic‐dye‐sensitized solar cell used in conjunction with a newly developed binary ionic‐liquid (solvent‐free) electrolyte (see current–voltage plot and photocurrent action spectrum for the sensitizer D205, the highest occupied molecular orbital of which is shown).
