fk102-co(iii)pf6-salt
Chemical structure of FK102-Co(III)PF6 Salt; Chemical formula: C24H21CoF18N9P3.

 

Applications

Tris(2-(1H-pyrazol-1-yl)pyridine)cobalt(III) tri[hexafluorophosphate], also known as FK102 Co(III)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.

Recommended use:

Liquid-based eletrolytes Typically 0.15-0.2M of Co(II) and ca. 0.05M Co(II)
Solid-state photovoltaic cells Up to 10 weight % added to the hole transport material system.
