      The modulation of properties in ferroelectric superlattices comes from electrostatic boundary conditions and cell distortions associated with interface-controlled epitaxial strain, but there is no clear picture of the specific relevance of each of these factors. Using a simple growth strategy, a separate control is achieved, allowing disentangling the relative contribution of electrostatic boundary conditions and strain. It turns out that the former rules the ferroelectric response, meanwhile the influence of the lattice strain is of secondary relevance.

      The interfacial charge transfer state energy of a crystalline rubrene/C60 solar cell is over 300 meV lower than that of an amorphous rubrene/C60 device. Despite that both amorphous and crystalline rubrene undergo singlet fission, this shift means that only the crystalline device can dissociate the low energy triplets generated by singlet fission and operate as a singlet fission solar cell.
