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.

TL;DR: The tailored selection of absorption onset energy through the quantum size effect, combined with deliberate engineering of the sequence of nanoparticle fusing and surface trap functionalization, underlie the superior performance achieved in this readily fabricated family of devices.

TL;DR: In this paper, the majority carrier mobility of colloidal quantum dot photovoltaic (CQD) films was investigated using x-ray photo-electron microscopy.

TL;DR: In this article, the authors quantitatively account for the observed 37% external quantum efficiency, showing that it results from the large depletion width and long carrier lifetime combined, and that the electron diffusion length of 0.1μm is comparable to neutral region width.

TL;DR: In this paper, the authors demonstrate photovoltaic devices effective across the visible and all the way out to 1700nm, using ethanedithiol as a bridging molecule to affect interparticle linking.
