|Full name||Tris(2-(1H-pyrazol-1-yl)pyridine)cobalt(III) tri[hexafluorophosphate]|
|Molecular weight||929.31 g/mol|
|HOMO / LUMO||1.06 V vs NHE|
|Classification / Family||Cobalt complex, Hole transport and dopant materials, Dye Sensitized Solar Cell (DSSC) Materials, Hole Conductor Cobalt Dopants, Organic Photovoltaic (OPV) Materials, Organic and Printed Electronics, Perovskite Materials|
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.
|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.|
