Triggering the Passivation Effect of Potassium Doping in Mixed-Cation Mixed-Halide Perovskite by Light Illumination
Fei Zheng,Fei Zheng,Weijian Chen,Tongle Bu,Kenneth P. Ghiggino,Fuzhi Huang,Yi-Bing Cheng,Patrick C. Tapping,Tak W. Kee,Baohua Jia,Xiaoming Wen +10 more
TL;DR: In this article, the photoluminescence properties and device performance of mixed-cation mixed-halide perovskite are dynamically monitored with and without K+ doping under bias light illumination via a confocal fluorescence microscope, together with ultrafast transient absorption as well as time-dependent and time-resolved PL measurements.
Journal ArticleDOI
Mobile Charge-Induced Fluorescence Intermittency in Methylammonium Lead Bromide Perovskite
Xiaoming Wen,Anita Ho-Baillie,Shujuan Huang,Rui Sheng,Sheng Chen,Hsien Chen Ko,Martin A. Green +6 more
TL;DR: This work investigates the fluorescence intermittency in vapor-assisted fabricated CH3NH3PbBr3 perovskite and provides unique insight into the charge accumulation and migration and thus is of crucial importance for device design and improvement.
Journal ArticleDOI
Light Illumination Induced Photoluminescence Enhancement and Quenching in Lead Halide Perovskite
Sheng Chen,Xiaoming Wen,Shujuan Huang,Fuzhi Huang,Yi-Bing Cheng,Martin A. Green,Anita Ho-Baillie +6 more
TL;DR: In this article, the effect of light illumination on CH3NH3PbI3 perovskites was investigated using steady state and time-resolved photoluminescence (PL) techniques.
Journal ArticleDOI
Mobile Ion Induced Slow Carrier Dynamics in Organic–Inorganic Perovskite CH3NH3PbBr3
Sheng Chen,Xiaoming Wen,Rui Sheng,Shujuan Huang,Xiaofan Deng,Martin A. Green,Anita Ho-Baillie +6 more
TL;DR: The key findings in this work suggest that ions are photoactivated or electro-activated and their accumulation at localized sites can result in a change of carrier dynamics and are useful for the understanding of instability of perovskite solar cells and shed light on the necessary strategies for performance improvement.
Journal ArticleDOI
Structure-Correlated Dual Fluorescent Bands in BSA-Protected Au25 Nanoclusters
TL;DR: In this paper, the temperature-dependent luminescence of bovine serum albumin-protected Au25 nanoclusters and their correlation with their structure was investigated, and it was concluded that band I exclusively originates from the icosahedral core of 13 Au(0) atoms and band II dominantly arises from the [−S−Au(I)−S-Au (I) −S −Au[S−] staples.
