16. The electrodes were chosen such that there is no barrier to charge collection. The shape of the corresponding I-V characteristics for this set of devices does not depend on the pyridine concentration, a further indication of the independence of charge collection on the morphology.

22. 0/I), was modeled effectively as linear combination of the absorption spectra for films of CdSe and films of P3HT. By using this description of the absorption spectrum, we assume that the domains of P3HT and CdSe stack parallel to the substrate. This model of the absorption profile is in agreement with the distribution of CdSe and P3HT domains across the film thickness observed in TEM images of the film cross-section.
23. The photocurrent spectrum, in units of -log [1 - EQE/100], was modeled effectively as a linear combination of the photocurrent spectrum of CdSe, in the same units, and absorption spectrum or photocurrent spectrum for films of P3HT. It is necessary to the use the absorption spectra of P3HT for films with > 60 wt.-% CdSe because the photocurrent spectrum is antibatic in devices made of only P3HT. At concentrations > 60 wt.-% the P3HT response in the blend photocurrent spectrum is symbatic.
