Abstract

Enhanced photocurrent from organic polymer-based photodiodes by blending PbS colloidal quantum dots (CQDs) are presented. The absorption spectra of nanocomposites of PbS CQDs and organic polymers, Poly[2-methoxy-5-(2′- ethylhexyloxy-pphenylenevinylene)] (MEH-PPV) and [6,6]- phenyl-C ₆₁-butyric acid methylester (PCBM), are the superposition of those of pristine constituents, indicating the absorption of the PbS CQDs contributes to the effective near-infrared light absorption for the photodiodes. The enhanced photocurrent for photodiodes made of MEH-PPV:PCBM:PbS is attributed to the excitons dissociation at the interfaces of PbS/MEH-PPV and PbS/PCBM, as well as charge transport in MEH-PPV and PCBM.
