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%.[1]

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%.[2][3]
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

    Dye-sensitized solar cells (DSCs) are 3rd generation solar cells combining the promise of high efficiency with low production costs.

    Next generation solar cells have the potential to achieve conversion efficiencies beyond the Shockley-Queisser (S-Q) limit while also significantly lowering production costs.

    Dr. Perini and Professor Correa-Baena discuss the latest research and effort to obtain higher performance and stability of perovskite materials.

    For several decades, the need for an environmentally sustainable and commercially viable source of energy has driven extensive research aimed at achieving high efficiency power generation systems that can be manufactured at low cost.

    Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
