Theoretical models of the squaraine‐C 60 donor–acceptor interface reported on page 3790 by C. Risko, J.‐L. Brédas, and co‐workers probe how molecules pack, mix, and move and the subsequent impact on interfacial electronic properties of organic solar cells. The 3D molecular shape, disordered packing, and thermal motion at room temperature render electronic couplings small, regardless of the orientation of the underlying squaraine layers. Such insight is vital to develop a more robust understanding of the photoconversion process and offers principles for materials design.
