Constructive molecular configurations for surface-defect passivation of perovskite photovoltaics
Rui Wang,Jingjing Xue,Kai-Li Wang,Zhao-Kui Wang,Zhao-Kui Wang,Yanqi Luo,David P. Fenning,Guangwei Xu,Selbi Nuryyeva,Tianyi Huang,Yepin Zhao,Jonathan Lee Yang,Jiahui Zhu,Minhuan Wang,Shaun Tan,Ilhan Yavuz,Kendall N. Houk,Yang Yang,Yang Yang +18 more
TL;DR: The chemical environment of a functional group that is activated for defect passivation was systematically investigated with theophylline, caffeine, and theobromine and hydrogen-bond formation between N-H and I (iodine) assisted the primary C=O binding with the antisite Pb defect to maximize surface-defect binding.
Journal ArticleDOI
Caffeine Improves the Performance and Thermal Stability of Perovskite Solar Cells
Rui Wang,Jingjing Xue,Lei Meng,Jin-Wook Lee,Zipeng Zhao,Pengyu Sun,Le Cai,Tianyi Huang,Zhengxu Wang,Zhao-Kui Wang,Zhao-Kui Wang,Yu Duan,Yu Duan,Jonathan Lee Yang,Shaun Tan,Yonghai Yuan,Yu Huang,Yang Yang +17 more
TL;DR: In this paper, 1,3,7-trimethylxanthine, a commodity chemical with two conjugated carboxyl groups better known by its common name caffeine, improves the performance and thermal stability of perovskite solar cells.
Journal ArticleDOI
Enabling low voltage losses and high photocurrent in fullerene-free organic photovoltaics
Jun Yuan,Tianyi Huang,Pei Cheng,Yingping Zou,Huotian Zhang,Jonathan Lee Yang,Sheng-Yung Chang,Zhenzhen Zhang,Wenchao Huang,Rui Wang,Dong Meng,Feng Gao,Yang Yang +12 more
TL;DR: A facile synthetic strategy is reported, where optoelectronic properties are delicately tuned by the introduction of electron-deficient-core-based fused structure into non-fullerene acceptors to achieve both low voltage loss and high current density, leading to a certified high efficiency.
Journal ArticleDOI
Tailored Phase Conversion under Conjugated Polymer Enables Thermally Stable Perovskite Solar Cells with Efficiency Exceeding 21
Lei Meng,Lei Meng,Chenkai Sun,Rui Wang,Wenchao Huang,Wenchao Huang,Zipeng Zhao,Pengyu Sun,Tianyi Huang,Jingjing Xue,Jin-Wook Lee,Chenhui Zhu,Yu Huang,Yongfang Li,Yang Yang +14 more
TL;DR: A low-cost and stable conjugated donor polymer (PTQ10) was introduced as interfacial layer in the planar n-i-p structured pero-SCs and proved to be an effective hole extraction layer due to the proper energy alignment with perovskite.
Journal ArticleDOI
Rational Tuning of Molecular Interaction and Energy Level Alignment Enables High-Performance Organic Photovoltaics
Rui Wang,Jun Yuan,Jun Yuan,Guangchao Han,Tianyi Huang,Wenchao Huang,Jingjing Xue,Hao Cheng Wang,Chunfeng Zhang,Chenhui Zhu,Pei Cheng,Dong Meng,Yuanping Yi,Kung-Hwa Wei,Yingping Zou,Yang Yang +15 more
TL;DR: The selection rule of the donor/acceptor blend is demonstrated by rationally considering the molecular interaction and energy level alignment, and highly efficient OPV devices using both-fluorinated or both-nonfluorinate donor/ acceptor blends are realized.
