Kebin Lin,Jun Xing,Li Na Quan,F. Pelayo García de Arquer,Xiwen Gong,Jianxun Lu,Liqiang Xie,Weijie Zhao,Di Zhang,Chuanzhong Yan,Wenqiang Li,Xinyi Liu,Yan Lu,Jeffrey Kirman,Edward H. Sargent,Qihua Xiong,Zhanhua Wei +16 more
TL;DR: In this article, the authors describe visible-light-emitting perovskite LEDs that surpass the quantum efficiency milestone of 20.3 per cent, which is achieved by a new strategy for managing the compositional distribution in the device.
Journal ArticleDOI

Yongcai Qiu,Wanfei Li,Wen Zhao,Guizhu Li,Yuan Hou,Meinan Liu,L. Z. Zhou,Fangmin Ye,Hongfei Li,Zhanhua Wei,Shihe Yang,Wenhui Duan,Yifan Ye,Jinghua Guo,Yuegang Zhang,Yuegang Zhang +15 more
TL;DR: The results indicate that the S@NG nanocomposite based Li/S cells have a great potential to replace the current Li-ion batteries.
Journal ArticleDOI
Hybrid halide perovskite solar cell precursors: colloidal chemistry and coordination engineering behind device processing for high efficiency.
Keyou Yan,Keyou Yan,Mingzhu Long,Tiankai Zhang,Zhanhua Wei,Haining Chen,Shihe Yang,Jianbin Xu +7 more
TL;DR: This work has identified that excess organic component can reduce the colloidal size of and tune the morphology of the coordination framework in relation to final perovskite grains and partial chlorine substitution can accelerate the crystalline nucleation process of perovkite.
Journal ArticleDOI
High-performance hole-extraction layer of sol-gel-processed NiO nanocrystals for inverted planar perovskite solar cells.
Zonglong Zhu,Yang Bai,Teng Zhang,Zhike Liu,Xia Long,Zhanhua Wei,Zilong Wang,Lixia Zhang,Jiannong Wang,Feng Yan,Shihe Yang +10 more
TL;DR: A simple sol-gel-processed NiO nanocrystal (NC) layer is used as the hole-transport layer in an inverted perovskite solar cell based on an inorganic hole-extracting layer, which observed a cell efficiency of 9.11 %, which is by far the highest reported for planar perovSKite solar cells based on a inorganic holes-extraction layer.
Journal ArticleDOI
Inkjet Printing and Instant Chemical Transformation of a CH3NH3PbI3/Nanocarbon Electrode and Interface for Planar Perovskite Solar Cells
TL;DR: A planar perovskite solar cell that incorporates a nanocarbon hole-extraction layer is demonstrated for the first time by an inkjet printing technique with a precisely controlled pattern and interface.
