Electrochemical Polymerization of Terthiophene-Fullerene Derivative and Its Optical Property for Organic Solar Cells

Poly(ethylenedioxy-substituted terthiophene - fullerene) was electrochemically synthesized on an ITO electrode, and its electronic and optical properties were measured. A large photocurrent of more than 3 μA/cm 2 was observed by irradiation at 50 mW/cm 2 with a halogen lamp using a wet cell containing 5 mM methyl viologen.
