Electropolymerization of conjugated polymers in mesoporous titania for photovoltaic applications

摘要

We report the electropolymerization of poly(3-methylthiophene) (P3MT) in mesoporous titania. X-ray photoelectron spectroscopy (XPS) depth-profiling experiments confirm that the polymer filled the pores continuously from the bottom electrode to the top surface of the mesoporous titania. Photovoltaic cells with this structure show 0.23 % power efficiency under 3.3mW/cm~2 514 nm monochromatic illumination.
