Journal ArticleDOI
A Wide Band Gap Polymer with a Deep Highest Occupied Molecular Orbital Level Enables 14.2% Efficiency in Polymer Solar Cells.
Sunsun Li,Long Ye,Wenchao Zhao,Hongping Yan,Bei Yang,Delong Liu,Wanning Li,Harald Ade,Jianhui Hou +8 more
TL;DR: A new benzodithiophene unit is developed and subtle side-chain modulation of the ester greatly influences the aggregation effects and molecular packing of polymer PDTB-EF-T, demonstrating the great potential of the DTBDT-EF unit for future organic photovoltaic applications.
Journal ArticleDOI
Efficient Charge Transfer and Fine-Tuned Energy Level Alignment in a THF-Processed Fullerene-Free Organic Solar Cell with 11.3% Efficiency.
Zhong Zheng,Omar Awartani,Bhoj Gautam,Delong Liu,Yunpeng Qin,Wanning Li,Alexander Bataller,Kenan Gundogdu,Harald Ade,Jianhui Hou +9 more
TL;DR: Fullerene-free organic solar cells show over 11% power conversion efficiency, processed by low toxic solvents, and the applied donor and acceptor in the bulk heterojunction exhibit almost the same highest occupied molecular orbital level, yet exhibit very efficient charge creation.
Journal ArticleDOI
Side Chain Selection for Designing Highly Efficient Photovoltaic Polymers with 2D-Conjugated Structure
Shaoqing Zhang,Shaoqing Zhang,Long Ye,Wenchao Zhao,Delong Liu,Huifeng Yao,Jianhui Hou,Jianhui Hou +7 more
TL;DR: In this paper, three conjugated polymers based on BDT and thieno[3,4-b]thiophene units with furan, thiophene and selenophene as side groups were synthesized and applied in polymer solar cells.
Journal ArticleDOI
Molecular design of a wide-band-gap conjugated polymer for efficient fullerene-free polymer solar cells
TL;DR: In this article, two p-type conjugated polymers with disparate optical and electronic properties, PB3T and PB2T, were developed and applied in fullerene-free polymer solar cells (PSCs).
Journal ArticleDOI
A Fluorinated Polythiophene Derivative with Stabilized Backbone Conformation for Highly Efficient Fullerene and Non-Fullerene Polymer Solar Cells
Shaoqing Zhang,Shaoqing Zhang,Yunpeng Qin,Yunpeng Qin,Mohammad Afsar Uddin,Bomee Jang,Wenchao Zhao,Delong Liu,Han Young Woo,Jianhui Hou,Jianhui Hou +10 more
TL;DR: In this article, a polythiophene derivative (PBDD4T) was used to increase the rotation barrier and stabilize its backbone conformation by introducing fluorine into the β- and β-position of the α-linked bithiophene segments.
