Harvest of near infrared light in PbSe nanocrystal-polymer hybrid photovoltaic cells
Abstract
We report a hybrid photovoltaic cell where PbSe nanocrystals were used to sensitize the conjugated polymer into the infrared. The device exhibited an incident monochromatic photon to current conversion efficiency of 1.3% at λ=805nm. Under 1 sun AM 1.5 illumination, the infrared response (780nm<λ<1600nm) of the embedded nanocrystals contributes to 33% of the overall photocurrent of the photovoltaic cell. The observed intensity dependences of the photocurrents have revealed the pseudomonomolecular recombination kinetics in the nanocrystal quantum dot polymer composite, indicating that the efficiency of the hybrid photovoltaic cells can be enhanced by reducing the potential barriers due to the ligand molecules at the surfaces of nanocrystals.

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.
