Mechanistic Insight into Supramolecular Polymerization in Water Tunable by Molecular Geometry
Supramolecular self-assembly in water based on non-covalent bonding is attracting major attention due to the potential of hydrogels and aqueous polymers in biomedical applications. Although supramolecular polymerization in organic solvents is well establis ...
CHINESE CHEMICAL SOC2022Visible light activated BINOL-derived chiroptical switches based on boron integrated hydrazone complexes
Chiral optical switches, which use light to control chirality in a reversible manner, offer unique properties and fascinating prospects in the areas of molecular switching and responsive systems, new photochromic materials and molecular data processing and ...
ROYAL SOC CHEMISTRY2022Dual-function artificial molecular motors performing rotation and photoluminescence
Molecular machines have caused one of the greatest paradigm shifts in chemistry, and by powering artificial mechanical molecular systems and enabling autonomous motion, they are expected to be at the heart of exciting new technologies. One of the biggest c ...
AMER ASSOC ADVANCEMENT SCIENCE2022Carbazol-phenyl-phenothiazine-based sensitizers for dye-sensitized solar cells
Shaik Mohammed Zakeeruddin, Felix Thomas Eickemeyer, Lukas Pfeifer, Zhongjin Shen, Dan Ren, Wei Huang, Yunfei Jiao, Yi Ding
Heteroaromatic units are commonly used as pi-spacers for sensitizers in dye-sensitized solar cells (DSSCs). Here, we investigated the influence of the pi-spacer on the photophysical properties, electrochemical properties and photovoltaic performance of car ...
ROYAL SOC CHEMISTRY2021Methylammonium Triiodide for Defect Engineering of High-Efficiency Perovskite Solar Cells
Michael Graetzel, Shaik Mohammed Zakeeruddin, Ursula Röthlisberger, Jacques-Edouard Moser, Mounir Driss Mensi, Felix Thomas Eickemeyer, Pascal Alexander Schouwink, Lukas Pfeifer, Thomas Paul Baumeler, Mathias Dankl, Ulf Anders Hagfeldt, Bowen Yang, Linfeng Pan, Paramvir Ahlawat, Essa Awadh R Alharbi, Claudia Esther Avalos, George Cameron Fish, Anurag Krishna, Olivier Ouellette, Viktor Skorjanc, Elsa John
The defects present in metal halide perovskite are deleterious to both the performance and stability of photovoltaic devices. Consequently, there is an intense focus on developing defect mitigation strategies. Herein we report a facile strategy that employ ...
2021Organic Ammonium Halide Modulators as Effective Strategy for Enhanced Perovskite Photovoltaic Performance
Michael Graetzel, Yuhang Liu, Lukas Pfeifer, Ulf Anders Hagfeldt, Seckin Akin, Bitao Dong
Despite rapid improvements in efficiency, long-term stability remains a challenge limiting the future up-scaling of perovskite solar cells (PSCs). Although several approaches have been developed to improve the stability of PSCs, applying ammonium passivati ...
