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.

Use this cobalt complexes to increase photovoltages of liquid electrolyte cells substantially or to achieve ultrahigh performance with solid state photovoltaic devices.
FK102 cobalt complexes offer guaranteed performance, high reproducibility, consistent results and are of highest purity. 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:
In liquid-based electrolytes: typically 0.15-0.2 M of Co(II) and ca. 0.05 M Co(II)
In solid-state photovoltaic cells: up to 10 weight % added to the hole transport material system.

FK 102 Co(III) PF₆?salt (FK 102) is a cobalt based p type dopant that is used in chemical doping of triarylamine based hole conductors. It can be used in the fabrication of dye sensitized solar cells (DSSCs). It has a redox potential of 1.06 V and shows no absorption in the visible region.
