Understanding Charge Transport in Molecular Blend Films in Terms of Structural Order and Connectivity of Conductive Pathways

The factors limiting charge carrier mobility in solution-processed small-molecule solar cells are investigated using a combination of X-ray scattering techniques and temperature dependent mobility measurements. It is found that order in the π–π stacking direction is correlated with the activation energy for transport while the connectivity of conducting domains is the primary limitation to hole transport in some systems.
