- 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.
