Small Molecule Solar Cells
In article number 1502285, the factors limiting charge carrier mobility in solution processed small molecule solar cells are investigated by Thuc-Quyen Nguyen and co-workers. 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.
Lithium and Sodium Ion Batteries
In article number 1502514, Yong Lei and co-workers present a comprehensive update on the fabrication and utilization of nanoarchitectured array electrodes for rechargeable lithium- and sodium-ion batteries. This advanced electrode design can enhance the battery performances by rapid ion transport in electrolytes, short ion diffusion in electrodes, directional electron transport pathways, large surface area, and high electrode stability.
