Strong coloration of nanoporous tungsten oxides by in-vacuo lithiation for all-solid-state electrochromic devices

Andreas Schueler, Anna Krammer, Maxime Lagier, Olivia Valérie Charlotte Bouvard, Luc Burnier

Electrochromic windows allow for an improved management of solar heat gains in buildings and enhanced visual comfort of building users. All-solid-state electrochromic devices can be especially durable. During their fabrication lithium has to be inserted, p ...

Optical properties of in vacuo lithiated nanoporous WO3:Mo thin films as determined by spectroscopic ellipsometry

Andreas Schueler, Josef Andreas Schuler, Maxime Lagier, Olivia Valérie Charlotte Bouvard, Luc Burnier, Aurélien Bertinotti

Incorporation of Mo into pure WO3 thin films is of interest for electrochromic devices, as it improves colour neutrality in the dark state. Existing literature still lacks reliable quantitative data on the complex dielectric function of such coatings. In t ...

Coatings with tailored electronic and optical properties for advanced glazing

Olivia Valérie Charlotte Bouvard

Modern envelope glazing relies on nanoscale coatings to meet a range of specific needs. Low emissivity coatings can improve the thermal performance of glazing thanks to a thin metallic film. However, the conductive nature of this layer leads to an attenuat ...

Evaluating the electricity saving potential of electrochromic glazing for cooling and lighting at the scale of the Swiss non-residential national building stock using a Monte Carlo model

Jean-Louis Scartezzini, Andreas Schueler, Olivia Valérie Charlotte Bouvard

Novel electrochromic glazing technology has been identified as an emerging option for reducing cooling and lighting electricity demand. As this technology is particularly promising for office building we assess the related technical energy saving potential ...

Color neutral nanocomposite nickel-tantalum oxide for electrochromic windows

Andreas Schueler, 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 ...

Solar heat gains through train windows: a non-negligible contribution to the energy balance

Josef Andreas Schuler, Olivia Valérie Charlotte Bouvard, Luc Burnier

The sector of transportation accounts for about one third of the total energy consumption in Switzerland. A monitoring campaign of the energy consumption of a regional train revealed the critical energy-consuming systems. Heating, cooling and ventilation w ...

Energy saving glazing with a wide band-pass FSS allowing mobile communication: up-scaling and characterisation

Andreas Schueler, Olivia Valérie Charlotte Bouvard, Luc Burnier

A real case study and characterisation of modern energy efficient windows allowing mobile communication is presented. An earlier study had shown that laser scribing of energy saving coatings allows highly reducing the microwave attenuation (from 30 to 1-3d ...

Development and characterization of electrochromic oxide and ion conductor deposited by reactive magnetron sputtering

Andreas Schueler, Olivia Valérie Charlotte Bouvard, Djamel Eddine Mansour

In order to modulate the solar gains of a building, electrochromic windows can be used. To improve their durability, inorganic solid state electrolytes are considered. This work reports on the investigation of tungsten trioxide (WO3) and lithium phosphorou ...
