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.
