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
Conformal quantum dot–SnO2 layers as electron transporters for efficient perovskite solar cells
Minjin Kim,Jaeki Jeong,Hai-Zhou Lu,Taemin Lee,Felix Eickemeyer,Yuhang Liu,In Woo Choi,Seunggun Choi,Yim Hyun Jo,Hak-Beom Kim,Sung-In Mo,Youngkwon Kim,Heun Soo Lee,Na Gyeong An,Shin uk Cho,Wolfgang Tress,Shaik M. Zakeeruddin,Anders Hagfeldt,Jin Young Kim,Michael Grätzel,Dong Suk Kim +20 more
TL;DR: Replacing the commonly used mesoporous–titanium dioxide electron transport layer with a thin layer of polyacrylic acid–stabilized tin(IV) oxide quantum dots enhanced light capture and largely suppressed nonradiative recombination at the ETL–perovskite interface, resulting in a certified power conversion efficiency of 25.4% and high operational stability.
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
High-efficiency non-fullerene organic solar cells enabled by a difluorobenzothiadiazole-based donor polymer combined with a properly matched small molecule acceptor
Jingbo Zhao,Yunke Li,Haoran Lin,Yuhang Liu,Yuhang Liu,Kui Jiang,Cheng Mu,Tingxuan Ma,Tingxuan Ma,Joshua Yuk Lin Lai,Huawei Hu,Huawei Hu,Demei Yu,He Henry Yan +13 more
TL;DR: In this paper, the authors reported high performance small molecule acceptor (SMA)-based organic solar cells (OSCs) enabled by the combination of a difluorobenzothiadiazole donor polymer named PffBT4T-2DT and a SMA named SF-PDI2.
Journal ArticleDOI
