A solvent-free ionic liquid electrolyte based on the SeCN-/(SeCN)3- redox couple has been employed for high-efficiency dye-sensitized nanocrystalline solar cells. For the first time an alternative redox couple has been identified to rival and even exceed the performance of the iodide/triiodide couple even at full sunlight. Unprecedented 7.5-8.3% power conversion efficiencies under AM 1.5 sunlight have been achieved for photovoltaic devices with solvent-free ionic liquid electrolytes.
