Abstract

The diffusion of I3 - in volatile and non-volatile electrolytes is investigated to confirm the effects on the performance of dye-sensitized solar cells (DSSCs). The ionic diffusion is controlled by using electrolyte mediums with diverse viscosities including acetonitrile, 3-methoxy-propionitrile, diethylene glycol dimethyl ether, and poly(ethylene glycol dimethyl ether) with three different molecular weights and varying I3 - concentrations. The diffusion flux in each electrolyte is characterized by scanning electrochemical microscopy. By measuring incident photon to current conversion efficiency, electrochemical impedance spectroscopy, and photovoltaic performance, the optimum diffusion flux of I3 - is suggested for the best efficiency of DSSCs.
