The design of materials needed for the storage, delivery, and conversion of (re)useable energy is still hindered by the lack of new, hierarchical molecular screening methodologies that encode information on more than one length scale. Using a molecular network theory as a foundation, we show that to describe charge transport in disordered materials the network methodology must be scaled-up. We detail the scale-up through the use of adjacency lists and depth first search algorithms for during operations on the adjacency matrix.

- The study uses Monte Carlo simulations to evaluate how different morphological structures in organic photovoltaics impact charge transport and device performance.
- Increasing the size of the domain in isotropic two-phase morphologies enhances the fill factor by 11.6% due to reduced tortuosity and fewer Coulombic barriers.
- In contrast, adding small aggregates of electron acceptors creates charge defects that decrease fill factors by an average of 23.3%, while idealized structures show a smaller decrease of 3.31% in fill factor when increasing domain size significantly.
- Overall, the results indicate that Coulomb interactions between charge carriers play a more significant role than exciton separation in smaller devices.
