Light-harvesting antennae for polymer solar cells

The authors demonstrate the incorporation of an artificial, extrinsic antenna into organic, conjugated polymer layers. This can lead to the independent optimization of spectral and spatial cross section for light absorption in organic solar devices. They report studies of three antenna layers, anthracene, 9,10-dichloroanthracene, and 9,10-diphenylanthracene, that are spin coated onto a poly[2-methoxy,5-(2methyl hexoxy)-1,4-phenylenevinylene] thin film.

Photon echo studies of conjugated polymers

The interplay between conjugation length and conformational disorder has a profound effect on the photophysics of polymer systems. From three pulse photon echo (3PE) studies, the coupling of nuclear motion to electronic transitions in MEH-PPV and a model oligomer is found to be instrumental in relaxation.
