Journal ArticleDOI
Cation and anion immobilization through chemical bonding enhancement with fluorides for stable halide perovskite solar cells
Nengxu Li,Shuxia Tao,Yihua Chen,Xiuxiu Niu,Chidozie Onwudinanti,Chen Hu,Zhiwen Qiu,Ziqi Xu,Guanhaojie Zheng,Ligang Wang,Yu Zhang,Liang Li,Huifen Liu,Yingzhuo Lun,Jiawang Hong,Xueyun Wang,Yuquan Liu,Haipeng Xie,Yongli Gao,Yongli Gao,Yang Bai,Shihe Yang,Shihe Yang,Geert Brocks,Geert Brocks,Qi Chen,Huanping Zhou +26 more
TL;DR: Li et al. as discussed by the authors employed fluoride to simultaneously passivate both anion and cation vacancies, by taking advantage of the extremely high electronegativity of fluoride, and obtained a power conversion efficiency of 21.46% (and a certified 21.3%-efficient cell) in a device based on the caesium, methylammonium (MA), and formamidinium (FA) triple-cation perovskite (Cs0.05FA0.41)Pb(I0.98Br0.02)3 treated with sodium
Journal ArticleDOI
From unstable CsSnI3 to air-stable Cs2SnI6: A lead-free perovskite solar cell light absorber with bandgap of 1.48 eV and high absorption coefficient
Xiaofeng Qiu,Bingqiang Cao,Shuai Yuan,Xiangfeng Chen,Zhiwen Qiu,Yanan Jiang,Qian Ye,Hongqiang Wang,Haibo Zeng,Jian Liu,Mercouri G. Kanatzidis +10 more
TL;DR: In this paper, a two-step sequential deposition method is developed to grow high-quality Bγ-CsSnI3 thin films and their unique phase change in atmosphere is explored in detail.
Journal ArticleDOI
Near Room Temperature, Fast-Response, and Highly Sensitive Triethylamine Sensor Assembled with Au-Loaded ZnO/SnO2 Core–Shell Nanorods on Flat Alumina Substrates
TL;DR: A near room working temperature and fast response triethylamine (TEA) gas sensor has been fabricated successfully by designing gold (Au)-loaded ZnO/SnO2 core-shell nanorods by employing pulsed laser deposition (PLD) and DC-sputtering methods.
Journal ArticleDOI
Highly sensitive and selective triethylamine-sensing properties of nanosheets directly grown on ceramic tube by forming NiO/ZnO PN heterojunction
TL;DR: In this article, a highly sensitive and selective nanostructured triethylamine (TEA) gas sensor has been fabricated successfully by designing PN heterojunction consisting of ZnO nanosheets and NiO nanoparticles.
Journal ArticleDOI
High triethylamine-sensing properties of NiO/SnO2 hollow sphere P-N heterojunction sensors
TL;DR: In this paper, NiO/SnO 2 PN junction was formed by depositing NiO nanoparticles onto the surface of SnO 2 hollow sphere sensors via a pulsed laser deposition (PLD) process.
