TL;DR: In this article , an asymmetric poly(3-hexylthiophene-2,5-diyl) (PY3Se-1V)-based binary all-polymer solar cells (all-PSCs) with photo-response approaching 1000 nm was developed.
Journal ArticleDOI
Role of self-assembled tetraoctylammonium bromide on various conjugated polymers in polymer light-emitting diodes
TL;DR: In this paper, the role of self-assembled tetraoctylammonium bromide (TOAB) on various conjugated polymers, namely green-emissive poly(9,9-dialkylfluorene) derivative (G-PF), super yellow poly(phenylenevinylene) (SY-PPV), and poly(3-hexylthiophene) (P3HT), in light-emitting devices based on these polymers was investigated.
Proceedings ArticleDOI

James G. Grote,John S. Zetts,Robert L. Nelson,Frank Kenneth Hopkins,Jeremy B. Huddleston,Perry P. Yaney,Cheng Zhang,William H. Steier,Min-Cheol Oh,Harold R. Fetterman,Alex K.-Y. Jen,Larry R. Dalton +11 more
TL;DR: In this article, the authors investigated various conductive and non-conductive polymers suitable for use as cladding layers in nonlinear optic (NLO) polymer based opto-electronic devices.
Journal ArticleDOI
Side-chain Substituents on Benzotriazole-based Polymer Acceptors Affecting the Performance of All-polymer Solar Cells.
TL;DR: In this paper , a series of PSMAs based on the benzotriazole (BTz)-core fused SMAs with different N-alkyl chains including branched 2-butyl octyl, linear n-octyl, and methyl on the BTz unit, namely PZT-C12, PZTs-C8, and PZt-C1, were presented.
Journal ArticleDOI
Characterization of coplanar poled electro optic polymer films for Si-photonic devices with multiphoton microscopy
Roland Himmelhuber,Soroush Mehravar,Oscar D. Herrera,Veysi Demir,Khanh Kieu,Jingdong Luo,Alex K.-Y. Jen,Robert A. Norwood,N. Peyghambarian +8 more
TL;DR: In this paper, coplanar poled electro optic (EO) polymer films on transparent substrates were imaged with a multiple-photon microscope in reflection and correlated the second-harmonic light intensity with the results of Pockels coefficient (r33) measurements.
