Description	Commercial graphene nanoplatelets in the form of optically transparent thin films on F-doped SnO2 (FTO) exhibited high electrocatalytic activity toward I3/I redox couple, particularly in electrolyte based on ionic liquid (Z952). The charge-transfer resistance, RCT, was smaller by a factor of 56 in ionic liquid, compared to values in traditional electrolyte based on methoxypropionitrile solution (Z946). Optical spectra and electrochemical impedance confirm that the film’s absorbance scales linearly with RCT1. Electrocatalytic properties of graphene nanoplatelets for the I3/I redox reaction are proportional to the concentration of active sites (edge defects and oxidic groups), independent of the electrolyte medium. Dye-sensitized solar cell (DSC) was assembled with this material as a cathode.
