Journal ArticleDOI
Perovskite light-emitting diodes based on solution-processed self-organized multiple quantum wells
Nana Wang,Lu Cheng,Ge Rui,Shuting Zhang,Yanfeng Miao,Wei Zou,Chang Yi,Yan Sun,Yu Cao,Rong Yang,Yingqiang Wei,Qiang Guo,You Ke,Maotao Yu,Yizheng Jin,Yang Liu,Qingqing Ding,Dawei Di,Le Yang,Guichuan Xing,He Tian,Chuanhong Jin,Feng Gao,Richard H. Friend,Jianpu Wang,Wei Huang,Wei Huang +26 more
TL;DR: Perovskite quantum wells yield highly efficient LEDs spanning the visible and near-infrared as discussed by the authors. But their performance is not as good as those of traditional LEDs, and their lifetime is shorter.
Journal ArticleDOI
Perovskite light-emitting diodes based on spontaneously formed submicrometre-scale structures
Yu Cao,Nana Wang,He Tian,Jingshu Guo,Yingqiang Wei,Hong Chen,Yanfeng Miao,Wei Zou,Kang Pan,Yarong He,Hui Cao,You Ke,Mengmeng Xu,Ying Wang,Ming Yang,Kai Du,Zewu Fu,Decheng Kong,Daoxin Dai,Yizheng Jin,Gongqiang Li,Hai Li,Qiming Peng,Jianpu Wang,Wei Huang,Wei Huang,Wei Huang +26 more
TL;DR: The formation of submicrometre-scale structure in perovskite light-emitting diodes can raise their external quantum efficiency beyond 20%, suggesting the possibility of both high efficiency and high brightness.
Journal ArticleDOI
Minimising efficiency roll-off in high-brightness perovskite light-emitting diodes.
Wei Zou,Renzhi Li,Shuting Zhang,Yunlong Liu,Yunlong Liu,Nana Wang,Yu Cao,Yanfeng Miao,Mengmeng Xu,Qiang Guo,Dawei Di,Li Zhang,Chang Yi,Feng Gao,Richard H. Friend,Jianpu Wang,Wei Huang,Wei Huang,Wei Huang +18 more
TL;DR: It is concluded that the efficiency roll-off in perovskite LEDs is mainly due to luminescence quenching which is likely caused by non-radiative Auger recombination.
Journal ArticleDOI
Oriented Quasi-2D Perovskites for High Performance Optoelectronic Devices
Rong Yang,Renzhi Li,Yu Cao,Yingqiang Wei,Yanfeng Miao,Wen Liang Tan,Xuechen Jiao,Xuechen Jiao,Hong Chen,Liangdong Zhang,Qing Chen,Huotian Zhang,Wei Zou,Yuming Wang,Ming Yang,Chang Yi,Nana Wang,Feng Gao,Christopher R. McNeill,Tianshi Qin,Jianpu Wang,Wei Huang,Wei Huang +22 more
TL;DR: Efficient and water-stable quasi-2D perovskite solar cells with a peak PCE of 18.20% by using 3-bromobenzylammonium iodide are demonstrated and can work well as light-emitting diodes (LEDs), exhibiting an external quantum efficiency of 3.85% and a long operational lifetime of ≈96 h at a high current density in air.
Journal ArticleDOI
Benzylamine-Treated Wide-Bandgap Perovskite with High Thermal-Photostability and Photovoltaic Performance
Yang Zhou,Feng Wang,Yu Cao,Jianpu Wang,Hong-Hua Fang,Maria Antonietta Loi,Ni Zhao,Ching-Ping Wong +7 more
TL;DR: In this paper, the thermal-photostability of mixed halide perovskites was investigated under various application conditions, and in particular combined light and heat stress, and it was found that the concerted effect of heat and light can induce both phase segregation and decomposition.
