Electrochemical Synthesis of POT for Electrochromic and Solar Cell Materials

Abstract:

POT (poly (o-toluidine)) was synthesized on ITO/glass by using electrochemical method and the effect of different reaction conditions such as scan rate, the concentrations of monomer and sulfuric acid, and cycle times on the POT was studied. The resulting POT was characterized by spectroscopy such as FT-IR, Roman, and UV-vis methods. The surface morphology of protruding island shape was recorded by scanning electronic microscope (SEM). The electrochromic properties were found that the color of the polymer can turn from green to blue reversibly by increasing the applied voltage. The anode of the solar cell was made of FTO/glass covered with nano-TiO₂/POT showed good photo-electron conversion performance which indicated the potential application in electrochromic and solar cell devices.
