Photodetection and Photovoltaic Properties of Polymer Composite Materials Based on Pentacene and Carbon Nanotube

An IR active photodetector device consisting of poly(vinyl carbazole) (PVK), PbSe quantum dot and single-walled carbon nanotubes (SWCNT) has been constructed. Efficient collection of IR photons in our devices followed by fast charge transfer and enhanced conduction in the polymer and SWNT networks results in a maximum EQE of ~2.6%.
