Abstract

image

Exciton dissociation pathways within a polymer bulk heterojunction film in a solar cell device is investigated by L. Yu, L. X. Chen, and co-workers on page 10. The blue fullerene derivative PCBM acts as an electron acceptor and the yellow ribbons represent the investigated low-bandgap polymer PTB7. The polymer forms both ordered pi-stacked domains and disordered domains within the film. This image was created by Nanjia Zhou from Northwestern University.
