摘要：

Single-wall carbon nanotube-polymer composite, having high electric conductivity was employed for organic photovoltaic cells. Acid treatment by a mixture of H2SO4/HNO3 cut the long entangled carbon nanotubes and improved dispersion into polymers. The composite films showed high electric conductivity depending on the concentration of CNTs. The photovoltaic cell, which has a layered structure composed of a spin-coated nanotube-polymer composite film and a deposited pigment film, showed about three times higher value of short-circuit photocurrent than that not including nanotubes. This result was attributed to the improvement of carrier transport in the polymer film.
