General description

FK 102 Co(III) TFSI salt is a cobalt(III) complex that can be used as a p-type dopant to control the type and density of charge carriers in both organic and inorganic semiconductors. The solubility of TFSI allows an increase in the doping potential for hole-conductors in electrochemical devices.

Application

FK 102 Co(III) TFSI salt can be majorly used in the fabrication of dye sensitized solar cells (DSSCs) and perovskite based solar cells (PSCs).
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.

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
