Journal ArticleDOI
Intrinsic non-radiative voltage losses in fullerene-based organic solar cells
Johannes Benduhn,Kristofer Tvingstedt,Fortunato Piersimoni,Sascha Ullbrich,Yeli Fan,Yeli Fan,Manuel Tropiano,Kathryn A. McGarry,Olaf Zeika,Moritz Riede,Christopher J. Douglas,Stephen Barlow,Seth R. Marder,Dieter Neher,Donato Spoltore,Koen Vandewal +15 more
TL;DR: In this paper, the authors expose a link between electron-vibrations coupling and non-radiative recombinations, derive a new limit for the efficiency of organic solar cells, and redefine their optimal optical gap.
Journal ArticleDOI
Design of Polymethine Dyes with Large Third-Order Optical Nonlinearities and Loss Figures of Merit
Joel M. Hales,Jonathan D. Matichak,Stephen Barlow,Shino Ohira,Kada Yesudas,Jean-Luc Brédas,Joseph W. Perry,Seth R. Marder +7 more
TL;DR: A design approach that involves enhancing the real part of the third-order polarizability of cyanine-like molecules through incorporation of polarizable chalcogen atoms into terminal groups is presented, while controlling the molecular length to obtain favorable one- and two-photon absorption resonances that lead to suitably low optical loss and appreciable dispersion enhancement of thereal part of γ.
Journal ArticleDOI
65 nm feature sizes using visible wavelength 3-D multiphoton lithography.
Wojciech Haske,Vincent W. Chen,Joel M. Hales,Wenting Dong,Stephen Barlow,Seth R. Marder,Joseph W. Perry +6 more
TL;DR: Three-dimensional multiphoton lithography at 520 nm has been used to fabricate polymeric woodpile photonic crystal structures that show stop bands in the near-infrared spectral region.
Journal ArticleDOI

Journal ArticleDOI
Ultralow Doping in Organic Semiconductors: Evidence of Trap Filling
Selina Olthof,Shafigh Mehraeen,Swagat K. Mohapatra,Stephen Barlow,Veaceslav Coropceanu,Jean-Luc Brédas,Seth R. Marder,Antoine Kahn +7 more
TL;DR: Using ultralow doping, a study of the controlled passivation of acceptor tail states in fullerene C(60) by the addition of electrons introduced by molecular n doping is presented.
