Highly Luminescent Phase-Stable CsPbI3 Perovskite Quantum Dots Achieving Near 100% Absolute Photoluminescence Quantum Yield.
Feng Liu,Yaohong Zhang,Chao Ding,Syuusuke Kobayashi,Takuya Izuishi,Naoki Nakazawa,Taro Toyoda,Tsuyoshi Ohta,Shuzi Hayase,Takashi Minemoto,Kenji Yoshino,Songyuan Dai,Qing Shen +12 more
TL;DR: It is shown that a high room-temperature photoluminescence quantum yield of up to 100% can be obtained in CsPbI3 perovskite QDs, signifying the achievement of almost complete elimination of the trapping defects.
Journal ArticleDOI
Colloidal Synthesis of Air-Stable Alloyed CsSn1–xPbxI3 Perovskite Nanocrystals for Use in Solar Cells
Feng Liu,Chao Ding,Yaohong Zhang,Teresa S. Ripolles,Taichi Kamisaka,Taro Toyoda,Shuzi Hayase,Takashi Minemoto,Kenji Yoshino,Songyuan Dai,Masatoshi Yanagida,Hidenori Noguchi,Qing Shen +12 more
TL;DR: The synthesis of alloyed perovskite quantum dot (QD), CsSn1-xPbxI3 is reported, which not only can be phase-stable for months in purified colloidal solution but also remains intact even directly exposed to ambient air, far superior to both of its parent Cs SnI3 and CsPbI3 QDs.
Journal ArticleDOI
Mixed Sn–Ge Perovskite for Enhanced Perovskite Solar Cell Performance in Air
Nozomi Ito,Muhammad Akmal Kamarudin,Daisuke Hirotani,Yaohong Zhang,Qing Shen,Yuhei Ogomi,Satoshi Iikubo,Takashi Minemoto,Kenji Yoshino,Shuzi Hayase +9 more
TL;DR: This work proposes a new type of perovskite material based on mixed tin and germanium, which showed a band gap around 1.4-1.5 eV as measured from photoacoustic spectroscopy, which is ideal from the perspective of solar cells.
Journal ArticleDOI
Boosting Photocatalytic CO2 Reduction on CsPbBr3 Perovskite Nanocrystals by Immobilizing Metal Complexes
Zhoujie Chen,Yangguang Hu,Jin Wang,Qing Shen,Yaohong Zhang,Chao Ding,Yu Bai,Guocan Jiang,Zhengquan Li,Nikolai Gaponik +9 more
TL;DR: In this article, metal complexes are used for converting CO2 into chemical fuels with a photocatalyst and sunlight, which is an appealing approach to address climate deterioration and energy crisis.
Journal ArticleDOI
All-Inorganic CsPb 1-x Ge x I 2 Br Perovskite with Enhanced Phase Stability and Photovoltaic Performance
Fu Yang,Daisuke Hirotani,Gaurav Kapil,Muhammad Akmal Kamarudin,Chi Huey Ng,Yaohong Zhang,Qing Shen,Shuzi Hayase +7 more
TL;DR: Novel inorganic CsPb1-x Gex I2 Br perovskite solar cells prepared in humid ambient atmosphere without a glovebox showed nearly no decay after 7 h measurement in 50-60 % relative humidity without encapsulation and the phase stability of the all-inorganic perovkite was effectively enhanced after germanium addition.
