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 ...

In-line electronic and structural characterization of reactively sputtered Cu-Co-Mn black spinel oxides

Andreas Schueler, Anna Krammer, Maxime Lagier

Cu-Co-Mn spinel oxide thin films are deposited by reactive magnetron sputtering. The x-ray diffraction (XRD) spectrum suggests a nanocrystalline spinel film when sputtered at approximate to 465 degrees C. In-line scanning tunneling microscopy confirms nano ...

Bringing colours to solar collectors: a contribution to an increased building "integrability"

Christian Roecker, Andreas Schueler, Maria Cristina Munari Probst

One main obstacle to facade integration of solar thermal collectors lies in the formal characteristics and low flexibility of available products. Major problems are the black and irregular appearance of their absorbers, their low dimensional flexibility an ...

Infrared and conductive properties of TCO films deposited by magnetron sputtering at different temperatures

Andreas Schueler, Anna Krammer

Low-emissive Transparent Conductive Oxide (TCO) coatings, such as Indium Tin Oxide (ITO) films, can be used to reduce radiative losses that affect Hybrid photovoltaic-thermal (PV-T) devices. This work shows the optical properties of ITO deposited by magnet ...

On the synergistic interplay between annealing temperature and time and additive concentration for efficient and stable FAPbI3 perovskite solar cells

Andreas Schueler, Arnaud Magrez, Wen Hua Bi, Federico Turci

Formamidinium-based lead triiodide perovskite (FAPI) is the workhorse candidate for highly efficient perovskite solar cells owing to its ideal bandgap and phase purity. An essential condition to that is the formation of a pure alpha-black phase, commonly t ...

Air channels create a directional light signal to regulate hypocotyl phototropism

Andreas Schueler, Jérémy Jacques Antonin Fleury

In plants, light direction is perceived by the phototropin photoreceptors, which trigger directional growth responses known as phototropism. The formation of a phototropin activation gradient across a photosensitive organ initiates this response. However, ...
