TL;DR: In this article, a unified model of how charge carriers travel in conjugated polymer films is proposed, and it is shown that in high-molecular-weight polymers, efficient charge transport is allowed due to a network of interconnected aggregates that are characterized by short-range order.

TL;DR: It is shown that the molecular packing motif (that is, herringbone versus slip-stacked) plays a decisive part in grain-boundary-induced transport anisotropy in PDI8-CN2, providing important guidelines for designing device-optimized molecular semiconductors.

TL;DR: In this article, a Fourier-transform peak shape analysis based on the method of Warren and Averbach (WA) was used to estimate the crystallite size and cumulative lattice disorder of three prototypical, high-performing organic semiconducting materials.

TL;DR: A unified model of how charge carriers travel in conjugated polymer films is proposed and it is shown that in high-molecular-weight semiconducting polymers the limiting charge transport step is trapping caused by lattice disorder, and that short-range intermolescular aggregation is sufficient for efficient long-range charge transport.

TL;DR: In this paper, the authors analyzed the absorption and emission spectra from fullerene and charge transfer excitons, and estimated a driving free energy of −0.14 ± 0.06 eV is required for efficient hole transfer.
