Journal ArticleDOI
Efficient organic solar cells processed from hydrocarbon solvents
Jingbo Zhao,Yunke Li,Guofang Yang,Guofang Yang,Kui Jiang,Haoran Lin,Herald Ade,Wei Ma,He Henry Yan +8 more
TL;DR: In this paper, the synergistic effects of a hydrocarbon solvent, a novel additive, a suitable choice of polymer side chain, and strong temperature-dependent aggregation of the donor polymer are used to produce active layers of organic solar cells in an environmentally friendly way.
Journal ArticleDOI
Fast charge separation in a non-fullerene organic solar cell with a small driving force
Jing Liu,Shangshang Chen,Deping Qian,Bhoj Gautam,Guofang Yang,Guofang Yang,Jingbo Zhao,Jonas Bergqvist,Fengling Zhang,Wei Ma,Harald Ade,Olle Inganäs,Kenan Gundogdu,Feng Gao,He Henry Yan +14 more
TL;DR: In this article, fast and efficient charge separation is essential to achieve high power conversion efficiency in organic solar cells (OSCs), and in state-of-the-art OSCs, this is usually achieved by a significant driv
Journal ArticleDOI
Terthiophene-Based D–A Polymer with an Asymmetric Arrangement of Alkyl Chains That Enables Efficient Polymer Solar Cells
Huawei Hu,Kui Jiang,Guofang Yang,Jing Liu,Zhengke Li,Haoran Lin,Yuhang Liu,Jingbo Zhao,Jie Zhang,Fei Huang,Yongquan Qu,Wei Ma,He Yan +12 more
TL;DR: The change from T4 to T3 comonomer units and the novel arrangement of alkyl chains in this study provide an important tool to tune the energy levels and morphological properties of donor polymers, which has an overall beneficial effect and leads to enhanced PSC performance.
Journal ArticleDOI
Donor polymer design enables efficient non-fullerene organic solar cells.
Zhengke Li,Kui Jiang,Guofang Yang,Guofang Yang,Joshua Yuk Lin Lai,Tingxuan Ma,Jingbo Zhao,Wei Ma,He Yan,He Yan +9 more
TL;DR: This study reports non-fullerene organic solar cells with efficiencies up to 10.9%, enabled by a novel donor polymer that exhibits strong temperature-dependent aggregation but with intentionally reduced polymer crystallinity due to the introduction of a less symmetric monomer unit.
Journal ArticleDOI
High-Performance Non-Fullerene Polymer Solar Cells Based on a Pair of Donor-Acceptor Materials with Complementary Absorption Properties.
Haoran Lin,Shangshang Chen,Zhengke Li,Joshua Yuk Lin Lai,Guofang Yang,Terry McAfee,Kui Jiang,Yunke Li,Yuhang Liu,Huawei Hu,Jingbo Zhao,Wei Ma,Harald Ade,He Yan +13 more
TL;DR: This work provides important guidance to improve the performance of non-fullerene polymer solar cells by combining a large- bandgap polymer PffT2-FTAZ-2DT with a small-bandgap acceptor IEIC.
