spectroscopy to study charge transfer in bulk heterojunction blends of PbSe quantum dots
with the semiconducting polymers poly-3-hexylthiophene (P3HT) and poly [2-methoxy-5-
(3′, 7′-dimethyloctyloxy)-para-phenylene vinylene](MDMO-PPV). PIA spectra from the
PbSe blends are compared to spectra from similar blends of the polymers with phenyl-C61-
butyric acid methyl ester (PCBM) and blends with CdSe quantum dots. We find that the …
