Photoinduced Carrier Generation in P3HT/PCBM Bulk Heterojunction Materials
Abstract
Using ultrafast spectroscopy, we have investigated the generation of mobile carriers in bulk heterojunction (BHJ) blends of regioregular poly(3-hexylthiophene), rrP3HT and the [6,6]-phenyl-C 61 butyric acid methyl ester fullerene derivative, PCBM. Mobile carriers are generated via a two-step process: initial ultrafast charge separation to an intermediate charge transfer (CT) bound state, followed by the transfer of carriers onto the bicontinuous networks. The yield of mobile carriers is decreased by recombination during the time spent in the CT bound state. After annealing the BHJ blends, the recombination loss of mobile carriers is reduced by a factor of 2.5, consistent with the observed increase in photovoltaic conversion efficiency.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
