Tailored Amphiphilic Molecular Mitigators for Stable Perovskite Solar Cells with 23.5% Efficiency
Hongwei Zhu,Hongwei Zhu,Yuhang Liu,Felix Eickemeyer,Linfeng Pan,Dan Ren,Marco A. Ruiz‐Preciado,Brian Carlsen,Bowen Yang,Xiaofei Dong,Zaiwei Wang,Hongli Liu,Shirong Wang,Shaik M. Zakeeruddin,Anders Hagfeldt,M. Ibrahim Dar,Xianggao Li,Michael Grätzel +17 more
TL;DR: It is found that simple surface treatment with tBBAI significantly accelerates the charge extraction from the perovskite into the spiro-OMeTAD hole-transporter, while retarding the nonradiative charge carrier recombination, boosting the power conversion efficiency (PCE) of the PSC and reducing the hysteresis to barely detectable levels.
Journal ArticleDOI

Journal ArticleDOI
Supramolecular Modulation of Hybrid Perovskite Solar Cells via Bifunctional Halogen Bonding Revealed by Two-Dimensional 19F Solid-State NMR Spectroscopy
Marco A. Ruiz‐Preciado,Dominik J. Kubicki,Albert Hofstetter,Lucie McGovern,Moritz H. Futscher,Amita Ummadisingu,Renana Gershoni-Poranne,Shaik M. Zakeeruddin,Bruno Ehrler,Lyndon Emsley,Jovana V. Milić,Michael Grätzel +11 more
TL;DR: A bifunctional supramolecular modulator, 1,2,4,5-tetrafluoro-3,6-diiodobenzene, which interacts with the surface of the triple-cation double-halide perovskite material via halogen bonding is introduced.
Journal ArticleDOI
Guanine‐Stabilized Formamidinium Lead Iodide Perovskites
Li Hong,Jovana V. Milić,Paramvir Ahlawat,Marko Mladenović,Dominik J. Kubicki,Farzaneh Jahanabkhshi,Dan Ren,María C. Gélvez-Rueda,Marco A.

TL;DR: A novel strategy for overcoming this challenge by employing low-dimensional hybrid perovskite materials comprising guaninium (G) organic spacer layers that act as stabilizers of the three-dimensional α-FAPbI3 phase is demonstrated.
Journal ArticleDOI
Comparison of nickel titanate (NiTiO3) powders synthesized by sol–gel and solid state reaction
TL;DR: In this article, the synthesis of NiTiO3 powders by the sol-gel and the solid state reaction methods was investigated, and their structural, electronic and optical properties required for their application in photocatalysis.
