Huatong Yao,Fujin Bai,Huawei Hu,Lingeswaran Arunagiri,Jianquan Zhang,Yuzhong Chen,Han Yu,Shangshang Chen,Tao Liu,Joshua Yuk Lin Lai,Yingping Zou,Harald Ade,He Yan +12 more
TL;DR: In this article, a PFBDT-IDTIC with a fluorinated donor polymer (PM6) was used to achieve a power conversion efficiency of 10.3% for single-junction all-polymer solar cells.
Journal ArticleDOI
Reduced Intramolecular Twisting Improves the Performance of 3D Molecular Acceptors in Non-Fullerene Organic Solar Cells.
Haoran Lin,Shangshang Chen,Huawei Hu,Lu Zhang,Tingxuan Ma,Joshua Yuk Lin Lai,Zhengke Li,Anjun Qin,Xuhui Huang,Ben Zhong Tang,Ben Zhong Tang,He Henry Yan,He Henry Yan +12 more
TL;DR: A small-molecular acceptor, tetraphenylpyrazine-perylenediimide tetramer (TPPz-PDI4), which has a reduced extent of intramolecular twisting compared to two other small- molescular acceptors is designed, and achieves the highest power conversion efficiency.
Journal ArticleDOI
Regio-Regular Polymer Acceptors Enabled by Determined Fluorination on End Groups for All-Polymer Solar Cells with 15.2 % Efficiency
Han Yu,Han Yu,Mingao Pan,Rui Sun,Indunil Agunawela,Jianquan Zhang,Yuhao Li,Zhenyu Qi,Han Han,Xinhui Zou,Wentao Zhou,Shangshang Chen,Joshua Yuk Lin Lai,Siwei Luo,Zhenghui Luo,Dahui Zhao,Xinhui Lu,Harald Ade,Fei Huang,Jie Min,Jie Min,He Yan,He Yan +22 more
TL;DR: In this paper, two regiospecific fluoro- and bromo- substituted end groups (IC-FBr-o and IC-Fbr-m) were synthesized and purified to construct two regio-regular polymer acceptors named PYF-T-o (T-m), which are then employed to construct all-polymer solar cells.
Journal ArticleDOI
