Journal ArticleDOI
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
Perovskite-polymer composite cross-linker approach for highly-stable and efficient perovskite solar cells.
Tae Hee Han,Jin-Wook Lee,Chungseok Choi,Shaun Tan,Changsoo Lee,Yepin Zhao,Zhenghong Dai,Nicholas De Marco,Sung-Joon Lee,Sang-Hoon Bae,Yonghai Yuan,Hyuck Mo Lee,Yu Huang,Yang Yang +13 more
TL;DR: Here Han et al. choose a polymer with proper molecular structure to crosslink the perovskite grains to greatly improve the device stability, and all photovoltaic parameters are significantly enhanced in the solar cells and the devices also show excellent stability.
Journal ArticleDOI
Interface and Defect Engineering for Metal Halide Perovskite Optoelectronic Devices.
TL;DR: A comprehensive review of various strategies that attempt to modify the interfacial characteristics, control the crystal growth, and understand the defect physics in metal halide perovskites, for both solar cell and LED applications, is presented.
Journal ArticleDOI
A Polymerization-Assisted Grain Growth Strategy for Efficient and Stable Perovskite Solar Cells
Yepin Zhao,Pengchen Zhu,Pengchen Zhu,Minhuan Wang,Shu Huang,Zipeng Zhao,Shaun Tan,Tae Hee Han,Tae Hee Han,Jin-Wook Lee,Jin-Wook Lee,Tianyi Huang,Rui Wang,Jingjing Xue,Dong Meng,Yu Huang,Jaime Marian,Jia Zhu,Yang Yang +18 more
TL;DR: Starting from the addition of small monomers in the PbI2 precursor, a polymerization-assisted grain growth strategy is introduced in the sequential deposition method, and a champion power conversion efficiency (PCE) of 23.0% is obtained.
