CAS Number 1392221-69-0
Tris(2-(1H-pyrazol-1-yl)pyridine)cobalt(II) di[hexafluorophosphate], commonly known as FK102 Co(II)PF6 Salt, is used as redox electrolyte in DSSC or hole transport and dopant materials in perovskite solar cells.
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.
