General description

FK 209 Co(III) TFSI salt (FK 209) is a Co(III) based complex that is used as a p-type dopant for the hole transporting material with a power conversion efficiency in the range of 9-12%.

Application

FK 209 can be used to induce a p-doping on PCDTBT and spiro-OMeTAD, which can be used as hole transporting materials in the fabrication of perovskite solar cells (PSCs) with an efficiency of 15-16%.
Use this cobalt complexes to increase photovoltages of liquid electrolyte cells substantially or to achieve ultrahigh performance with solid state photovoltaic devices.

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
