The Cover Feature shows the critical influence of the lateral substituents on the molecular packing in organic semiconductor thin films. The methoxyphenyl lateral substituent in N ‐annulated perylene‐based hole transporters can improve intermolecular stacking and improve connectivity between intermolecular aggregate domains in the solid films, leading to improved hole mobility and power conversion efficiency of the perovskite solar cells. More information can be found in the Full Paper by Li et al. on page 672 in Issue 4, 2018 (DOI: 10.1002/cssc.201702379).
