Magnetic and optical properties in degenerated transition metal and Ga co-substituted ZnO nanocrystals

Reinis Ignatans

In order to study the influence of itinerant electrons on magnetic properties of transition metal substituted ZnO nanocrystals, nanopowders containing different amounts of Ga and fixed amounts of Fe, Ni and Mn ions were synthesized. The ions of different t ...

Color neutral nanocomposite nickel-tantalum oxide for electrochromic windows

Josef Andreas Schuler, Olivia Valérie Charlotte Bouvard

Electrochromic windows can darken on demand to limit the solar gains entering a building to reduce the risk of overheating, while preserving the view towards the exterior. Yet, the switching speed and contrast as well as the durability of commercial produc ...

Non‐Planar and Flexible Hole‐Transporting Materials from Bis‐Xanthene and Bis‐Thioxanthene Units for Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Giulia Grancini

Two new hole‐transporting materials (HTMs), BX‐OMeTAD and BTX‐OMeTAD , based on xanthene and thioxanthene units, respectively, and bearing p ‐methoxydiphenylamine peripheral groups, are presented for their use in perovskite solar cells (PSCs). The novelty ...

Predicting the thermal performance of thermochromic flat plate solar collectors

Anna Krammer, Josef Andreas Schuler

A thermochromic vanadium dioxide (VO2) based absorber coating is proposed. The optical response of the multilayered absorber is first simulated, then, the spectral reflectance of the deposited absorber is measured. The determined solar absorptance and ther ...

Tailored lead iodide growth for efficient flexible perovskite solar cells and thin-film tandem devices

Romain Carron, Fan Fu

Flexible perovskite solar cells (PSCs) hold great promise for the low-cost roll-to-roll production of lightweight single- and multijunction photovoltaic devices. Among the different deposition methods used for the perovskite absorber, the two-step hybrid v ...

Indoor Light Enhanced Photocatalytic Ultra-Thin Films on Flexible Non-Heat Resistant Substrates Reducing Bacterial Infection Risks

Sami Rtimi

Photocatalytic antibacterial sol-gel coated substrates have been reported to kill bacteria under light or in the dark. These coatings showed non-uniform distribution, poor adhesion to the substrate and short effective lifetime as antibacterial surfaces. Th ...

Micro-reflectance and transmittance spectroscopy: a versatile and powerful tool to characterize 2D materials

Andras Kis, Dumitru Dumcenco, Yue Niu

Optical spectroscopy techniques such as differential reflectance and transmittance have proven to be very powerful techniques for studying 2D materials. However, a thorough description of the experimental setups needed to carry out these measurements is la ...

Spectroelectrochemical analysis of the mechanism of (photo)electrochemical hydrogen evolution at a catalytic interface

Florian Le Formal, Matthew Thomas Mayer, Stanley David Tilley

Multi-electron heterogeneous catalysis is a pivotal element in the ( photo) electrochemical generation of solar fuels. However, mechanistic studies of these systems are difficult to elucidate by means of electrochemical methods alone. Here we report a spec ...
