TL;DR: Procedures for testing organic solar cell devices and modules with respect to stability and operational lifetime are described and generally agreed test conditions and practices are generally agreed to allow ready comparison between laboratories and to help improving the reliability of reported values.
Journal ArticleDOI
Structural control of mixed ionic and electronic transport in conducting polymers.
Jonathan Rivnay,Sahika Inal,Brian Collins,Michele Sessolo,Eleni Stavrinidou,Xenofon Strakosas,Christopher J. Tassone,Dean M. DeLongchamp,George G. Malliaras +8 more
TL;DR: It is shown that bulk ionic and electronic mobilities are simultaneously affected by processing-induced changes in nano- and meso-scale structure in PEDOT:PSS films, and that domain purification on addition of dispersion co-solvents limits ion mobility, even while electronic conductivity improves.
Journal ArticleDOI
Microstructural Characterization and Charge Transport in Thin Films of Conjugated Polymers
TL;DR: The characterization techniques that provide information used to enhance the understanding of structure/property relationships in semiconducting polymers are reviewed.
Journal ArticleDOI
Connecting dopant bond type with electronic structure in N-doped graphene.
Theanne Schiros,Dennis Nordlund,Lucia Palova,Deborah Prezzi,Liuyan Zhao,Keun Soo Kim,Ulrich Wurstbauer,Christopher Gutierrez,Dean M. DeLongchamp,Cherno Jaye,Daniel A. Fischer,Hirohito Ogasawara,Lars G. M. Pettersson,David R. Reichman,Philip Kim,Mark S. Hybertsen,Abhay Pasupathy +16 more
TL;DR: It is shown that different N-bond types, including graphitic, pyridinic, and nitrilic, can exist in a single, dilutely N-doped graphene sheet, indicating that control over the dopant bond type is a crucial requirement in advancing graphene electronics.
Journal ArticleDOI
Molecular origin of high field-effect mobility in an indacenodithiophene–benzothiadiazole copolymer
Xinran Zhang,Hugo Bronstein,Auke Jisk Kronemeijer,Jeremy Smith,Youngju Kim,Youngju Kim,R. Joseph Kline,Lee J. Richter,Thomas D. Anthopoulos,Henning Sirringhaus,Kigook Song,Martin Heeney,Weimin Zhang,Iain McCulloch,Dean M. DeLongchamp +14 more
TL;DR: It is argued that charge transport in high-mobility semiconducting polymers is quasi one-dimensional, that is, predominantly occurring along the backbone, and requires only occasional intermolecular hopping through short π-stacking bridges.
