摘要：

The effective exciton diffusion length of poly(3-hexylthiophene) (P3HT) can be improved with resonance-energy transfer from P3HT to poly(N-dodecyl-2,5-bis(2'-thienyl)pyrrole-2,1,3-benzothia-diazole) (PTPTB), a low-bandgap polymer, which results in a threefold increase of the photocurrent. Directional resonance energy transfer to the exciton-splitting interface has the potential to overcome a number of limitations associated with exciton transport in polymer photovoltaic cells.
