Batteries play a vital role in the ongoing energy transition, driving the demand for safer, energy denser and higher performing energy storage solutions. This has propelled research of solid-state batteries. Halide electrolytes, with high ionic conductivities and high oxidation stabilities, have attracted tremendous interest. Currently, the main...

Batteries are an important aspect of sustainable energy technologies, as they can be used either for the storage of electric energy for the grid or for the electrification of the transport fleet, making these sectors less reliant on fossil fuels (chapter 1). The Li-ion battery has revolutionized the world in many ways, enabling portable electric...

Metal-halide perovskites deposited by wet-chemical deposition have demonstrated great potential for various electronic applications, including solar cells. A remaining question is how light-induced excess charges become distributed over such polycrystalline material. Here, we examine the local conductive properties of MAPbI<sub>3</sub> and...

Most highly Li-conducting solid electrolytes (σ<sub>RT</sub> &gt; 10<sup>-3</sup> S cm<sup>-1</sup>) are unstable against lithium-metal and suffer from detrimental solid-electrolyte decomposition at the lithium-metal/solid-electrolyte interface. Solid electrolytes that are stable against lithium metal thus offer a direct route to stabilize...

Co-evaporation of metal halide perovskites by thermal evaporation is an attractive method since it does not require harmful solvents and enables precise control of the film thickness. Furthermore, the ability to manipulate the Fermi level allows the formation of a graded homojunction, providing interesting opportunities to improve the charge...

Tm<sup>2+</sup>-doped halides exhibit excellent properties for use in Luminescence Solar Concentrator (LSC) applications. Such LSCs consist of a glass waveguide with small Copper-Indium- Selenide (CIS) solar cells attached to its edges. The waveguide contains a luminescent coating based on a Tm<sup>2+</sup>-doped halide, whose 4f125d1 absorption...

The prospect of using Tm<sup>2+</sup>-doped halides for luminescence solar concentrators (LSCs) requires a thorough understanding of the temperature dependent Tm<sup>2+</sup> excited states dynamics that determines the internal quantum efficiency (QE) and thereby the efficiency of the LSC. In this study we investigated the dynamics in CaX<sub...

Wide-band-gap perovskites such as methylammonium lead bromide (MAPB) are promising materials for tandem solar cells because of their potentially high open-circuit voltage, which is yet still far below the maximum limit. The relatively short charge-carrier lifetimes deduced from time-resolved photoluminescence (TRPL) measurements seem in...

The parameters governing the performance of a luminescent solar concentrator (LSC) are determined for sputtered thin-films of NaI:Tm<sup>2+</sup>, CaBr<sub>2</sub>:Tm<sup>2+</sup>, and CaI<sub>2</sub>:Tm<sup>2+</sup>. These parameters are determined by using six gradient thin film material libraries, combinatorially sputtered from metallic...

Halide assays are important for the study of enzymatic dehalogenation, a topic of great industrial and scientific importance. Here we describe the development of a very sensitive halide assay that can detect less than a picomole of bromide ions, making it very useful for quantifying enzymatic dehalogenation products. Halides are oxidised...

Reversible leaching of palladium nanoparticles occurs in a variety of catalytic reactions including cross-couplings, amination, the Heck reaction, etc. It is complemented by capturing of soluble palladium species on the surface of nanoparticles and de novo formation of nanoparticles from Pd precatalysts. We report here a detailed computational...
