基于SeCN-/(SeCN)3-氧化还原偶对的无溶剂离子液体电解质被用于高效染料敏化纳米晶太阳能电池。首次发现了一种替代氧化还原偶对，即使在充足的阳光下，其性能也能与碘化物/三碘化物偶对相媲美，甚至超过。使用无溶剂离子液体电解质的光伏器件在AM 1.5阳光下实现了前所未有的7.5−8.3%的功率转换效率。
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.
