Abstract

By tuning frontier orbital energies through selective halogenation of the periphery of the organic framework, new light harvesting electron acceptors based on boron subphthalocyanine chloride (SubPc) can be made, report Ross Hatton, Michael Shipman, Tim Jones, and co-workers on p. 352. Planar heterojunction organic photo-voltaics made using a Cl6-SubPc acceptor deliver an exceptionally high open-circuit voltage, good power conversion efficiency, and improved operational stability in comparison to similar devices made using C60 as the acceptor material.
