Journal ArticleDOI
Solution-processed PbS quantum dot infrared photodetectors and photovoltaics
Steve Mcdonald,Gerasimos Konstantatos,Shiguo Zhang,Paul W. Cyr,Ethan J. D. Klem,Larissa Levina,Edward H. Sargent +6 more
TL;DR: Sittingizing conjugated polymers with infrared-active nanocrystal quantum dots provides a spectrally tunable means of accessing the infrared while maintaining the advantageous properties of polymers, and makes use of the wavelength tunability afforded by the nanocrystals to show photocurrent spectra tailored to three different regions of the infrared spectrum.
Journal ArticleDOI
Photoconductivity from PbS-nanocrystal∕semiconducting polymer composites for solution-processible, quantum-size tunableinfrared photodetectors
TL;DR: In this paper, the authors reported photoconductivity at infrared wavelengths, 975-1300nm, from a conjugated polymer poly[2-methoxy-5-(2′-ethylhexyloxy-p-phenylenevinylene)] (MEH-PPV) sensitized with PbS nanocrystals (∼5nm diameter).
Journal ArticleDOI
Enhanced infrared photovoltaic efficiency in PbS nanocrystal/semiconducting polymer composites: 600-fold increase in maximum power output via control of the ligand barrier
TL;DR: In this paper, a comparison of photoconductive performance of PbS nanocrystal/polymer composite devices containing either oleic acid-capped or octylamine capped nanocrystals (NCs) is presented.

Three-dimensional bicontinuous heterostructures, method of making, and their application in quantum dot-polymer nanocomposite photodetectors and photovoltaics
Edward H. Sargent,Steve Mcdonald,Shiguo Zhang,Larissa Levina,Gerasimos Konstantatos,Paul W. Cyr +5 more
TL;DR: In this article, a three-dimensional bicontinuous heterostructure is proposed for photodetecting and photovoltaic devices working in the visible and the near-infrared.
