The emergence of metal halide perovskite materials has triggered a revolutionary change in optoelectronic devices. Due to their outstanding optoelectronic properties and defect tolerance, metal halide perovskites can be used for a wide range of application ...

Infrared light management is crucial to maximize the optical performance of crystalline Si-based single junction and tandem solar cells. For this end, a low refractive index dielectric is typically inserted under the rear metal and an electrical contact is ...

In this work, we introduce a p-NiO/LiNiO stack grown via low-temperature deposition processes, offering an effective alternative for creating localized p-type regions in GaN devices. This stack combines a high hole concentration p-NiO film ([h] = 2 × 1019 ...

The central aim of this thesis is to investigate single molecule phenomena in self-assembled plasmonic nanocavities, focusing on achieving single molecule sensitivity within these highly confined electromagnetic environments. While self-assembled nanocavit ...

Steel-copper multi-material structures produced via Additive Manufacturing pose challenges in laser co-processing and microstructural control. This work employs neutron imaging, Electron Backscatter Diffraction (EBSD), and Energy Dispersive Spectroscopy (E ...

Identifying sources of nonradiative recombination and quantifying charge carrier extraction in halide perovskite solar cells are important in further developing this thin-film technology. Steady-state and time-resolved photoluminescence (TRPL), in combinat ...

Perovskite-silicon (Si) tandem solar cells are the most prominent contenders to succeed single-junction Si cells that dominate the market today. Yet, to justify the added cost of inserting a perovskite cell on top of Si, these devices should first exhibit ...

Carbonyl-containing materials employed in state-of-the-art hybrid lead halide perovskite solar cells (PSCs) exhibit a strong structure-dependent electron donor effect that predominates in defect passivation. However, the impact of the molecular spatial con ...

Zinc is the most abundant and broadly studied metal oxide semiconductor. Its photophysical properties include optical, electrical, magnetic, catalytic, sensing, energy storage, antibacterial, anti-oxidant, and drug delivery applications have been extensive ...

This article presents a comprehensive investigation into the functionalization of methoxyphenylazobenzene using electron-directing groups located at the meta position relative to the azo group. Spectroscopic analysis of meta-functionalized azobenzenes reve ...

From hydropower to wind power, renewable energy is converted to electricity, putting the electric grid at the crossroads of the green energy generation and consumption. The grid must also adapt and scale up to an increased capacity and to the stochastic na ...

Chemical environment and precursor-coordinating molecular interactions within a perovskite precursor solution can lead to important implications in structural defects and crystallization kinetics of a perovskite film. Thus, the opto-electronic quality of s ...

Ammonium fluoride (NH₄F) exhibits a variety of crystalline phases depending on temperature and pressure. By employing Raman spectroscopy and synchrotron X-ray diffraction beyond megabar pressures (up to 140 GPa), we have here observed a novel dense solid p ...

Antimicrobial surfaces limit the spread of infectious diseases. To date, there is no antimicrobial coating that has widespread use because of short-lived and limited spectrum efficacy, poor resistance to organic material, and/or cost. Here, we present a pa ...
