CH3NH3SnxPb(1-x)I3 Perovskite Solar Cells Covering up to 1060 nm.
Yuhei Ogomi,Atsushi Morita,Syota Tsukamoto,Takahiro Saitho,Naotaka Fujikawa,Qing Shen,Taro Toyoda,Kenji Yoshino,Shyam S. Pandey,Tingli Ma,Shuzi Hayase +10 more
TL;DR: Photovoltaic performances of all-solid state Sn/Pb halide-based perovskite solar cells, which has the following composition: F-doped SnO2 layered glass/compact titania layer/porous titanialayer/CH3NH3SnxPb(1-x)I3/regioregular poly(3-hexylthiophene-2,5-diyl).
Journal ArticleDOI
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
Lead-free tin-halide perovskite solar cells with 13% efficiency
Kohei Nishimura,Muhammad Akmal Kamarudin,Daisuke Hirotani,Kengo Hamada,Qing Shen,Satoshi Iikubo,Takashi Minemoto,Kenji Yoshino,Shuzi Hayase,Shuzi Hayase +9 more
TL;DR: In this article, the A site cation of tin halide perovskite solar cells was replaced with formamidinium cation to achieve a tolerance factor of nearly 1.
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
All-Solid Perovskite Solar Cells with HOCO-R-NH3+I– Anchor-Group Inserted between Porous Titania and Perovskite
Yuhei Ogomi,Atsushi Morita,Shota Tsukamoto,Takahiro Saitho,Qing Shen,Taro Toyoda,Kenji Yoshino,Shyam S. Pandey,Tingli Ma,Shuzi Hayase +9 more
TL;DR: In this article, a HOCO-R-NH3+I monolayer working as an anchor for perovskite (CH3NH3PbI3) was inserted between the surface of porous metal oxide (titania or alumina) and the PEROVI3.
