Combined Precursor Engineering and Grain Anchoring Leading to MA-Free, Phase-Pure, and Stable α-Formamidinium Lead Iodide Perovskites for Efficient Solar Cells
Xufeng Ling,Hongwei Zhu,Weidong Xu,Cheng Liu,Linfeng Pan,Dan Ren,Jianyu Yuan,Bryon W. Larson,Carole Grätzel,Ahmad R. Kirmani,Olivier Ouellette,Anurag Krishna,Jianguo Sun,Chunyang Zhang,Youyong Li,Shaik M. Zakeeruddin,Jing Gao,Yuhang Liu,James R. Durrant,Joseph M. Luther,Wanli Ma,Michael Grätzel +21 more
TL;DR: In this article, a combined strategy of precursor engineering and grain anchoring was proposed to achieve MA-free and phase-pure α-FAPbI3 films for perovskite solar cells.
Journal ArticleDOI
Electrochemical investigations of the oxidation reactons of tetrathiofulvalene in micellar solution
Mark J. Eddowes,Michael Grätzel +1 more
TL;DR: In this paper, the authors demonstrate that the electrochemical oxidation of tetrathiofulvalene in aqueous/CTAC micellar solution takes place via two one-electron steps, representing the formation of the mono-and di-cation radicals, respectively.
Journal ArticleDOI
Ultrafast photoinduced electron transfer in coumarin 343 sensitized TiO2-colloidal solution
TL;DR: In this paper, a visible pump/white light probe is used to investigate the electron injection reaction allowing to observe simultaneously the relaxation of the excited dye, the injection process of the electron, the cooling of the injected electron and the charge recombination reaction.
Journal ArticleDOI
Multielectron storage and hydrogen generation with colloidal semiconductors
Michael Grätzel,Jacques-E. Moser +1 more
TL;DR: Multielectron storage and hydrogen generation by light is achieved in aqueous dispersions of ultrafine TiO(2) particles when the amphiphilic viologen derivative N-tetradecyl-N'-methyl-4,4'-dipyridinium dichloride (C(14)MV(2+)) is used as an electron relay.
Journal ArticleDOI
Spectroscopic ellipsometry of RuO2 films prepared by metalorganic chemical vapor deposition
TL;DR: In this article, thin films on RuO2 were deposited on glass by metalorganic chemical vapor deposition using tristrifluoroacetylacetonate•ruthenium (III) [Ru(tfa)3] as precursor.
