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
Improved Understanding of the Electronic and Energetic Landscapes of Perovskite Solar Cells: High Local Charge Carrier Mobility, Reduced Recombination, and Extremely Shallow Traps
TL;DR: Kinetic and frequency analysis of the transient complex conductivity strongly support the superiority of the perovskite, based on a significant suppression of charge recombination, an extremely shallow trap depth (10 meV), and a low concentration of these trapped states (less than 10%).
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.
