Intermolecular charge transport under the influence of an external electric field is simulated in systems of conjugated polymer chains. Disorder is included in our model by varying the interchain coupling. Without the external field present the charge is extended over several chains in regions of strong interchain coupling, i.e., diffusion across regions of low interchain coupling is not possible. In the presence of a sufficiently strong external electric field, the electrons can drift (tunnel) through such regions. The average time the charge spends in the most disordered regions is therefore negligible compared to the residing time of the electron in the more ordered regions.
