Journal ArticleDOI
Long-Range Balanced Electron- and Hole-Transport Lengths in Organic-Inorganic CH3NH3PbI3
Guichuan Xing,Nripan Mathews,Shuangyong Sun,Swee Sien Lim,Yeng Ming Lam,Michael Grätzel,Michael Grätzel,Subodh Mhaisalkar,Tze Chien Sum +8 more
TL;DR: Two studies show, using a variety of time-resolved absorption and emission spectroscopic techniques, that perovskite materials manifest relatively long diffusion paths for charge carriers energized by light absorption, highlighting effective carrier diffusion as a fruitful parameter for further optimization.
Journal ArticleDOI
Low-temperature solution-processed wavelength-tunable perovskites for lasing
Guichuan Xing,Nripan Mathews,Swee Sien Lim,Natalia Yantara,Xinfeng Liu,Dharani Sabba,Michael Grätzel,Michael Grätzel,Subodh Mhaisalkar,Tze Chien Sum +9 more
TL;DR: It is revealed that solution-processed organic-inorganic halide perovskites (CH3NH3PbX3), which demonstrated huge potential in photovoltaics, also have promising optical gain and may show electrically driven lasing.
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
The origin of high efficiency in low-temperature solution-processable bilayer organometal halide hybrid solar cells
Shuangyong Sun,Teddy Salim,Nripan Mathews,Martial Duchamp,Chris Boothroyd,Guichuan Xing,Tze Chien Sum,Yeng Ming Lam,Yeng Ming Lam +8 more
TL;DR: In this paper, the authors reported the origin of the high efficiency in solution-processable bilayer solar cells based on methylammonium lead iodide (CH3NH3PbI3) and [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM).
Journal ArticleDOI
Two-Photon-Pumped Perovskite Semiconductor Nanocrystal Lasers.
Yanqing Xu,Qi Chen,Chunfeng Zhang,Rui Wang,Hua Wu,Xiaoyu Zhang,Guichuan Xing,William W. Yu,Xiaoyong Wang,Yu Zhang,Min Xiao +10 more
TL;DR: Stable two-photon-pumped lasing is demonstrated at a remarkable low threshold by coupling CsPbBr3 nanocrystals with microtubule resonators and these findings suggest perovskite nanocry crystals can be used as excellent gain medium for high-performance frequency-up-conversion lasers toward practical applications.
