Journal ArticleDOI
Moderate doping leads to high performance of semiconductor/insulator polymer blend transistors
Guanghao Lu,James C. Blakesley,James C. Blakesley,Scott Himmelberger,Patrick Pingel,Patrick Pingel,Johannes Frisch,Ingo Lieberwirth,Ingo Salzmann,Martin Oehzelt,Riccardo Di Pietro,Alberto Salleo,Norbert Koch,Dieter Neher +13 more
TL;DR: It is shown that blends comprising a small amount of semiconducting polymer mixed into an insulating polymer matrix actually perform very poorly in the undoped state, and that mobility and on/off ratio are improved dramatically upon moderate doping.
Journal ArticleDOI
The role of regioregularity, crystallinity, and chain orientation on electron transport in a high-mobility n-type copolymer.
Robert Steyrleuthner,Riccardo Di Pietro,Brian Collins,Frank Polzer,Scott Himmelberger,Marcel Schubert,Zhihua Chen,Shiming Zhang,Alberto Salleo,Harald Ade,Antonio Facchetti,Dieter Neher +11 more
TL;DR: The comparison between the regioregular and regioirregular polymers shows how the use of large planar functional groups leads to improved charge transport, with mobilities that are less affected by chemical and structural disorder with respect to classic semicrystalline polymers such as poly(3-hexylthiophene).
Journal ArticleDOI
Experimental evidence that short-range intermolecular aggregation is sufficient for efficient charge transport in conjugated polymers
Suhao Wang,Simone Fabiano,Scott Himmelberger,Skomantas Puzinas,Xavier Crispin,Alberto Salleo,Magnus Berggren +6 more
TL;DR: It is demonstrated that local aggregation over very few chains is a sufficient mesoscopic structure to ensure high mobility, with charge transport mainly occurring along the polymer backbones, and that extended crystallinity is not necessary.
Journal ArticleDOI
Structural Factors That Affect the Performance of Organic Bulk Heterojunction Solar Cells
TL;DR: In this paper, structural factors influence the photogeneration and collection of charge carriers as well as charge carrier recombination and the related open-circuit voltage in polymer:fullerene solar cells.
Journal ArticleDOI
Enhanced Photovoltaic Performance of Indacenodithiophene-Quinoxaline Copolymers by Side- Chain Modulation
Dongfeng Dang,Dongfeng Dang,Weichao Chen,Scott Himmelberger,Qiang Tao,Qiang Tao,Angelica Lundin,Renqiang Yang,Weiguo Zhu,Alberto Salleo,Christian Müller,Ergang Wang +11 more
TL;DR: In this article, two pairs of indacenodithiophene (IDT) and quinoxaline-based copolymers with meta- or para-hexyl-phenyl side chains on the IDT unit are synthesized.
