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.
