Journal ArticleDOI
A low cost and high performance polymer donor material for polymer solar cells
Chenkai Sun,Fei Pan,Haijun Bin,Jianqi Zhang,Lingwei Xue,Beibei Qiu,Zhixiang Wei,Zhi-Guo Zhang,Yongfang Li,Yongfang Li +9 more
TL;DR: A low-cost polymer donor poly[(thiophene)-alt-(6,7-difluoro-2-(2-hexyldecyloxy)quinoxaline)] (PTQ10), which is synthesized with high overall yield via a two-step process with a yield close to 90% and shows high photovoltaic performance with efficiency of 12%.
Journal ArticleDOI
Cathode engineering with perylene-diimide interlayer enabling over 17% efficiency single-junction organic solar cells.
Jia Yao,Beibei Qiu,Zhi-Guo Zhang,Lingwei Xue,Rui Wang,Chunfeng Zhang,Shanshan Chen,Shanshan Chen,Qiuju Zhou,Chenkai Sun,Chenkai Sun,Changduk Yang,Min Xiao,Lei Meng,Yongfang Li +14 more
TL;DR: The results indicate that PDINN is an effective cathode interfacial material and interlayer engineering via suitable intermolecular interactions is a feasible approach to improve device performance of OSCs.
Journal ArticleDOI
Highly Efficient Fullerene-Free Organic Solar Cells Operate at Near Zero Highest Occupied Molecular Orbital Offsets.
Shuixing Li,Lingling Zhan,Chenkai Sun,Haiming Zhu,Guanqing Zhou,Weitao Yang,Minmin Shi,Chang-Zhi Li,Jianhui Hou,Yongfang Li,Hongzheng Chen +10 more
TL;DR: Investigating a series of fullerene-free organic solar cells based on six different donor:acceptor (D:A) blends with varied highest occupied molecular orbital (HOMO) offsets demonstrates not only the validity of high-performance OSCs operating at the near zero HOMO offsets but also the charge dynamic insights of these blends, which will help gain understanding on the further improvement of Oscs.
Journal ArticleDOI
High Efficiency Polymer Solar Cells with Efficient Hole Transfer at Zero Highest Occupied Molecular Orbital Offset between Methylated Polymer Donor and Brominated Acceptor.
Chenkai Sun,Shucheng Qin,Rui Wang,Shanshan Chen,Shanshan Chen,Fei Pan,Beibei Qiu,Ziya Shang,Lei Meng,Chunfeng Zhang,Min Xiao,Changduk Yang,Yongfang Li,Yongfang Li +13 more
TL;DR: The results prove the feasibility of efficient hole transfer and high efficiency for the PSCs with zero ∆EHOMO(D-A), which is greatly valuable for understanding the charge transfer process and achieving high PCE of the P SCs.
Journal ArticleDOI
