Temperature dependent threshold for amplified emission from hybrid lead perovskite films
Yang Liu, Ju Wang, Ning Zhu +6
The optical amplification emission of hybrid lead perovskite attracted great research interests. We systematically examined and compared temperature dependent optical amplification…
Revealing two heat-annealing related photoproduct systems and widely existed subgrain domains in organolead perovskite
Wei Wang, Yu Li, Xiangyuan Wang +8
For highly interested organolead perovskite based solar cells, the photoproducts are regarded as the co-existed exciton and free carriers. In this study, we carefully re-examined t…
Dynamical co-existence of excitons and free carriers in perovskite probed by density-resolved fluorescent spectroscopic method
Wei Wang, Yu Li, Xiangyuan Wang +7
Using transient fluorescent spectra at time-zero, we develop a density-resolved fluorescent spectroscopic method for investigating photoproducts in CH3NH3PbI3 perovskite and relate…
Direct Observation of Long Electron-Hole Diffusion Distance in CH3NH3PbI3 Perovskite Thin Film
Yu Li, Weibo Yan, Yunlong Li +5
In high performance perovskite based solar cells, CH3NH3PbI3 is the key material. We carried out a study on charge diffusion in spin-coated CH3NH3PbI3 perovskite thin film by trans…
On chip, high-sensitivity thermal sensor based on high-Q polydimethylsiloxane-coated microresonator
Bei-Bei Li, Qing-Yan Wang, Yun-Feng Xiao +4
A high-sensitivity thermal sensing is demonstrated by coating a layer of polydimethylsiloxane (PDMS) on the surface of a silica toroidal microresonator on a silicon wafer. Possessi…
Quantum electrodynamics in a whispering-gallery microcavity coated with a polymer nanolayer
Yun-Feng Xiao, Chang-Ling Zou, Peng Xue +5
Quasi-transverse-electric and -transverse-magnetic fundamental whispering gallery modes in a polymer-coated silica microtoroid are theoretically investigated and demonstrated to po…
Broadband enhancement of light harvesting in luminescent solar concentrator
Yun-Feng Xiao, Chang-Ling Zou, Yi-Wen Hu +4
Luminescent solar concentrator (LSC) can absorb large-area incident sunlight, then emit luminescence with high quantum efficiency, which finally be collected by a small photovoltai…
