Journal ArticleDOI
Tuning the electron-deficient core of a non-fullerene acceptor to achieve over 17% efficiency in a single-junction organic solar cell
Can Zhu,Jun Yuan,Fangfang Cai,Lei Meng,Huotian Zhang,Honggang Chen,Jing Li,Beibei Qiu,Hongjian Peng,Shanshan Chen,Shanshan Chen,Yunbin Hu,Changduk Yang,Feng Gao,Yingping Zou,Yongfang Li +15 more
TL;DR: In this article, a new member of the Y-series acceptor family, Y18, was designed and synthesized, which adopts a fused benzotriazole segment with unique luminescence properties as its electron-deficient core.
Journal ArticleDOI
Understanding energetic disorder in electron-deficient-core-based non-fullerene solar cells
Jun Yuan,Chujun Zhang,Honggang Chen,Honggang Chen,Can Zhu,Can Zhu,Sin Hang Cheung,Beibei Qiu,Fangfang Cai,Qingya Wei,Wei Liu,Hang Yin,Rui Zhang,Jidong Zhang,Ye Liu,Huotian Zhang,Weifang Liu,Hongjian Peng,Junliang Yang,Lei Meng,Feng Gao,Shu Kong So,Yongfang Li,Yingping Zou +23 more
TL;DR: In this article, a facile design strategy is reported by introducing the "wing" (alkyl chains) at the terminal of the DA′D central core of the A-DA′D-A type acceptor to achieve a favorable and ordered molecular orientation and therefore facilitate charge carrier transport.
Journal ArticleDOI
Semitransparent solar cells with over 12% efficiency based on a new low bandgap fluorinated small molecule acceptor
Mei Luo,Chunyan Zhao,Jun Yuan,Jiefeng Hai,Fangfang Cai,Yunbin Hu,Hongjian Peng,Yiming Bai,Yiming Bai,Zhan'ao Tan,Zhan'ao Tan,Yingping Zou +11 more
TL;DR: In this paper, a fused dithienothiophen[3,2-b]-pyrrolobenzotriazole (BTA-core)-based low bandgap electron acceptor, namely Y14, has been designed and synthesized to address this issue.
Journal ArticleDOI
Efficient organic solar cells based on a new “Y-series” non-fullerene acceptor with an asymmetric electron-deficient-core
Fangfang Cai,Can Zhu,Can Zhu,Jun Yuan,Zhe Li,Lei Meng,Wei Liu,Hongjian Peng,Lihui Jiang,Yongfang Li,Yingping Zou +10 more
TL;DR: A new "Y-series" non-fullerene acceptor, Y21, bearing an asymmetric electron-deficient-core (DA'D) and fluorinated dicyanomethylene derivatives as flanking groups, was designed and synthesized for organic solar cell applications.
Journal ArticleDOI
An asymmetric small molecule acceptor for organic solar cells with a short circuit current density over 24 mA cm−2
Fangfang Cai,Hongjian Peng,Honggang Chen,Jun Yuan,Jiefeng Hai,Tsz-Ki Lau,Ju Wang,Yunbin Hu,Wei Liu,Xinhui Lu,Yingping Zou +10 more
TL;DR: In this article, an asymmetric hexacyclic fused donor-acceptor-donor (DA′D) type central framework and two electron-deficient 2-(5,6-difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile moieties were used for asymmetric SMA-based organic solar cells.
