Near-infrared photoconductive and photovoltaic devices using single-wall carbon nanotubes in conductive polymer films

Prototypical Al/single-wall carbon nanotube (SWNT)-polymer/indium tin oxide thin-film devices that exhibit promising photoconductive and photovoltaic responses in a broad spectral range, typically from 300 to 1600 nm is fabricated. Three devices are observed that include the near-infrared (NIR) light harvesting properties of semi-SWNTs, the electronic transport properties of the SWNTs in combination with that of the polymer matrices and probably the charge/energy transfer processes between the nanotubes and the polymers.
