(c, d) from left to right show a charge-separated state and a partly delocalized state.
Over the course of eight 10 ps simulations, the lowest lying excitation samples a variety of electronic states ranging from localized excitons to charge-separated, charge-transfer, and delocalized states. Figure 2 shows the charge density for four typical eigenstates encountered over the course of a given simulation.
(iv) Delocalized states (DLOC), characterized as having <50% of the electron/hole density on a single PPV or PCBM molecule.
According to McKeever & Chen (1997), electrons are not translated from the ground state to the conduction band straight but via delocalized states. The question of where these delocalized excited states are situated remains unanswered.
