Cd-113 Solid-State NMR at 21.1 T Reveals the Local Structure and Passivation Mechanism of Cadmium in Hybrid and All-Inorganic Halide Perovskites

David Lyndon Emsley, Dominik Józef Kubicki, Albert Hofstetter, Daniel Prochowicz, Brennan James Walder

Cadmium doping has recently emerged as an efficacious strategy for defect suppression and band gap tuning in hybrid as well as all-inorganic halide perovskites. However, the cadmium speciation in these materials is unknown. Here, we use high-field cadmium- ...

Atomistic origins of the limited phase stability of Cs+-rich FAxCs(1-x)PbI3 mixtures

Michael Graetzel, David Lyndon Emsley, Ursula Röthlisberger, Ariadni Boziki, Simone Meloni, Dominik Józef Kubicki, Aditya Mishra

Mixed cation perovskites, [HC(NH2)2]xCs(1-x)PbI3, (FAxCs(1-x)PbI3) with x=0.8 achieve high solar cell power conversion efficiencies (PCEs) while exhibiting long-term stability under ambient conditions. In this work, we perform density functional theory (DF ...

Phase transitions, screening and dielectric response of CsPbBr3

Dominik Józef Kubicki

Cesium-lead-bromide (CsPbBr3) is the simplest all inorganic halide perovskite. It serves as a reference material for understanding the exceptional solar cell properties of the organic-inorganic hybrid halide perovskites and is itself discussed as an altern ...

Intermediate Phase Enhances Inorganic Perovskite and Metal Oxide Interface for Efficient Photovoltaics

Michael Graetzel, David Lyndon Emsley, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Dominik Józef Kubicki, Yuhang Liu, Jiahuan Zhang, Zaiwei Wang, Aditya Mishra, Claudia Esther Avalos

Interfacial modification is crucial to fully develop the potential of semiconductor devices, including the revolutionary halide perovskite-based optoelectronics, such as photovoltaics, light-emitting diodes, and photodetectors. The all-inorganic halide per ...

Atomic-Level Microstructure of Efficient Formamidinium-Based Perovskite Solar Cells Stabilized by 5-Ammonium Valeric Acid Iodide Revealed by Multinuclear and Two-Dimensional Solid-State NMR

Michael Graetzel, Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Ursula Röthlisberger, Jacques-Edouard Moser, Jovana Milic, Marko Mladenovic, Dominik Józef Kubicki, Fabrizio Giordano, Dan Ren

Chemical doping of inorganic–organic hybrid perovskites is an effective way of improving the performance and operational stability of perovskite solar cells (PSCs). Here we use 5-ammonium valeric acid iodide (AVAI) to chemically stabilize the structure of ...

Atomic-level passivation mechanism of ammonium salts enabling highly efficient perovskite solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Jacques-Edouard Moser, Jingshan Luo, Dominik Józef Kubicki, Fabrizio Giordano, Brennan James Walder, Andrés Burgos Caminal, Essa Awadh R Alharbi

The high conversion efficiency has made metal halide perovskite solar cells a real break-through in thin film photovoltaic technology in recent years. Here, we introduce a straight-forward strategy to reduce the level of electronic defects present at the i ...

A Factor Two Improvement in High-Field Dynamic Nuclear Polarization from Gd(III) Complexes by Design

David Lyndon Emsley, Marinella Mazzanti, Anne-Sophie Chauvin, Dominik Józef Kubicki, Gabriele Stevanato, Georges Guévork Jean-Jacques Menzildjian

Gadolinium(III) complexes have recently been demonstrated to have potential as polarizing agents for high-field dynamic nuclear polarization (DNP) NMR spectroscopy. By tailoring the ligand design to reduce the zero-field splitting (ZFS), we demonstrate a q ...

Nucleobase pairing and photodimerization in a biologically derived metal-organic framework nanoreactor

David Lyndon Emsley, Berend Smit, Dominik Józef Kubicki, Kyriakos Stylianou, Ngoc Tú Nguyên, Peter George Boyd, Andrzej Gladysiak, Samantha Lynn Anderson

Biologically derived metal-organic frameworks (bio-MOFs) are of great importance as they can be used as models for bio-mimicking and in catalysis, allowing us to gain insights into how large biological molecules function. Through rational design, here we r ...
