Journal ArticleDOI
Aggregation and morphology control enables multiple cases of high-efficiency polymer solar cells.
Yuhang Liu,Jingbo Zhao,Zhengke Li,Cheng Mu,Wei Ma,Huawei Hu,Kui Jiang,Haoran Lin,Harald Ade,He Yan +9 more
TL;DR: The uncovered aggregation and design rules yield three high-efficiency (>10%) donor polymers and will allow further synthetic advances and matching of both the polymer and fullerene materials, potentially leading to significantly improved performance and increased design flexibility.
Journal ArticleDOI
Quantitative relations between interaction parameter, miscibility and function in organic solar cells
Long Ye,Huawei Hu,Masoud Ghasemi,Tonghui Wang,Tonghui Wang,Brian Collins,Brian Collins,Joo-Hyun Kim,Kui Jiang,Joshua H. Carpenter,Hong Li,Hong Li,Zhengke Li,Terry McAfee,Jingbo Zhao,Xian Kai Chen,Xian Kai Chen,Joshua Lin Yuk Lai,Tingxuan Ma,Jean-Luc Brédas,Jean-Luc Brédas,He Yan,Harald Ade +22 more
TL;DR: This work establishes a quantitative ‘constant-kink-saturation’ relation between χaa and the fill factor in organic solar cells that is verified in detail in a model system and delineated across numerous high- and low-performing materials systems, including fullerene and non-fullerene acceptors.
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
A tetraphenylethylene core-based 3D structure small molecular acceptor enabling efficient non-fullerene organic solar cells.
Yuhang Liu,Yuhang Liu,Cheng Mu,Kui Jiang,Jingbo Zhao,Yunke Li,Lu Zhang,Zhengke Li,Joshua Yuk Lin Lai,Huawei Hu,Tingxuan Ma,Tingxuan Ma,Rongrong Hu,Demei Yu,Xuhui Huang,Ben Zhong Tang,He Yan +16 more
TL;DR: The work provides a new molecular design approach to efficient non-fullerene OSCs based on 3D-structured small-molecule acceptors based on tetraphenylethylene core-based small molecular acceptor with a unique 3D molecular structure.
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.
