Electrochemical characterization of sub-micro-gram amounts of organic semiconductors using scanning droplet cell microscopy

► Scanning droplet cell microscopy (SDCM) was adapted to work in nonaqueous solutions. ► Full electrochemical characterization is possible with sub-micro-gram amounts. ► P3HT on ITO/glass, a standard material for organic solar cells was studied. ► Two reversible oxidation/reduction peaks have been characterized by EIS, CV, PotStat. ► Electrochemical and chemical doping changes conductivity by three orders of magnitude.
