CA 2519608

The present invention relates to photodetectors and photovoltaics and in particular lead sulphide quantum dot infrared photodectors and photovoltaic devices. The present invention includes sensitizing conjugated polymers with infrared active nanocrystal quantum dots to provide a spectrally tunable means of accessing the infrared while maintaining the advantageous properties of polymers. The present invention uses such a nanocomposite approach in which quantum size effect- tuned PbS nanocrystals sensitize the conjugated polymer poly(2-methoxy-5-(2'- ethylhexyloxy- p-phenylenevinylene)] (MEH-PPV) into the infrared. The present invention achieves, in a solution-processed device and with sensitivity far beyond 800 nm, harvesting of infrared-photogenerated carriers and the demonstration of an infrared photovoltaic effect. The present invention also exploits the wavelength tunability afforded by the nanocrystals to show photocurrent spectra tailored to three different regions of the infrared spectrum.
