Verständnisprobleme beim Mechanismus der Exzitonendissoziation in organischen Bulk‐Heterokontakt‐Solarzellen erwuchsen aus Faktoren wie Phasenverunreinigungen, der Domänengröße und dem Ausmaß der Exzitondelokalisierung. In ihrer Zuschrift auf S. 7586 ff. präsentieren T. J. Marks, M. A. Ratner et al. nun ein neues Modell der Exzitondissoziation, das ein experimentell bestätigtes, schnelles diffusionsbegrenztes...
Organic photovoltaics (OPVs) offer the opportunity for cheap, lightweight and mass‐producible devices. However, an incomplete understanding of the charge generation process, in particular the timescale of dynamics and role of exciton diffusion, has slowed further progress in the field. We report a new Kinetic Monte Carlo model for the exciton dissociation mechanism in OPVs that addresses the origin...
