Description générale

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.

Application

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.

In this work, we report a new cobalt(III) complex, tris[2-(1H-pyrazol-1-yl)pyrimidine]cobalt(III) tris[bis(trifluoromethylsulfonyl)imide] (MY11), with deep redox potential (1.27 V vs NHE) as dopant for 2,2',7,7'-tetrakis-(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD). This dopant possesses, to the best of our knowledge, the deepest redox potential among all

Following pioneering work, solution-processable organic-inorganic hybrid perovskites-such as CH3NH3PbX3 (X = Cl, Br, I)-have attracted attention as light-harvesting materials for mesoscopic solar cells. So far, the perovskite pigment has been deposited in a single step onto mesoporous metal oxide films

We report a combined experimental and computational investigation to understand the nature of the interactions between cobalt redox mediators and TiO(2) surfaces sensitized by ruthenium and organic dyes, and their impact on the performance of the corresponding dye-sensitized solar cells
