Analysis of Triplet Exciton Loss Pathways in PTB7:PC71BM Bulk Heterojunction Solar Cells.
Hannes Kraus,Michael C. Heiber,Stefan Väth,Julia Kern,Carsten Deibel,Andreas Sperlich,Vladimir Dyakonov +6 more
TL;DR: In PTB7:PC71BM devices, TE formation via EBT is impacted by fullerene domain size at low temperature, but at room temperature, EBT does not represent a dominant loss pathway.
Binding energy of singlet excitons and charge transfer complexes in MDMO-PPV:PCBM solar cells
TL;DR: In this article, the influence of an external electric field on the photoluminescence intensity of singlet excitons and charge transfer complexes was investigated for a poly[2-methoxy-5-(3',7'-dimethyl octyloxy)-1,4-phenylenevinylene] (MDMO-PPV) diode and a bulk heterojunction of the PPV in combination with [6,6]-phenyl-C61 butyric acid methylester (PCBM), respectively.

TL;DR: In this article, a concept is introduced which allows for reduced Coulomb interaction in organic solar cells and as such for enhanced power conversion efficiencies, based on the introduction of electrically insulating, nanostructured high-k materials into the organic matrix, which do not contribute to the charge carrier transport, but enhance the effective permittivity of the organic active layer.
