FK102-Co(III)PF6 Salt, chemically tris(2-(1H-pyrazol-1-yl)pyridine)cobalt(III) tri[hexafluorophosphate], is a cobalt complex supplied by Ossila as an orange powder with a purity above 98%. It serves two main roles in solar cell research: a p-type dopant for hole transport layer (HTL) materials in perovskite solar cells, and a redox electrolyte component in dye-sensitized solar cells (DSSC).
Compared with redox electrolytes based on triiodide, cobalt complexes of this kind tend to raise device photovoltage. The benefit is most noticeable under weak illumination, such as indoor lighting, where power output can rise significantly.
The compound has a molecular weight of 929.31 g/mol, an energy level of 1.06 V vs NHE, and dissolves in acetonitrile, making it convenient for solution processing of hole conductor formulations.
- Doping hole transport layer materials in perovskite solar cells.
- Acting as a redox electrolyte in dye-sensitized solar cells.
- Serving as a p-type dopant for organic semiconductors in solid-state DSSC.
