Tris(2-(1H-pyrazol-1-yl)pyridine)cobalt(III) tri[bis(trifluoromethane)sulfonimide, FK102-Co(III)TFSi Salt is commonly used as electrolyte for DSSC or p-type dopant for Spiro-MeOTAD in perovskite solar cells, together with Lithium bis(trifluoromethanesulfonyl)imide (LiTFSi) and 4-tert-Butylpyridine (TBP).
In comparison to triiodide-based redox electrolytes, cobalt complexes in general increase photovoltages and particularly at lower light levels (e.g. for indoor applications), significantly increase device power output.
