TL;DR: In this article, an in-depth study of bilayer cells consisting of a donor/acceptor interface between zinc phthalocyanine (ZnPc) and fullerene (C60) is conducted and devices with the typically deposited standing up (edge-on) orientation are compared to those with ZnPC lying flat (face-on).

TL;DR: In this article, the electron-hole separation at the prototypical donor-acceptor interface P3HT/PCBM was investigated by means of a combination of molecular dynamics simulations, quantum-chemical methods, and classical microelectrostatic calculations.

TL;DR: Photophysical properties of diketopyrrolopyrrole derivatives substituted with oligothiophenes are investigated and comparison of absorption and fluorescence excitation spectra show the presence of both J- and H-type absorption bands in the solid phase.

TL;DR: It is shown that electrostatic effects at the interface of model 1D stacks profoundly modify the energy landscape explored by charge carriers in the photoconversion process and that these can be tuned by chemical design.

TL;DR: In this article, a semi-empirical Valence-Bond/Hartree-Fock level analysis was performed on model 1D aggregates to assess the electronic structure at pentacene/C60 heterojunctions and it was shown that the asymmetry of the electrostatic potential at the interface profoundly impacts the energy landscape explored by the charges.
