Potential of magnetron sputtered magnesium fluoride containing thin films for the multilayer design of coloured coatings for solar collector glazing

Jean-Louis Scartezzini, Paul Muralt, Stefan Mertin

In this work, the potential of magnetron sputtered magnesium fluoride (MgF2) and MgF2 containing composite coatings for coloured solar collector glazing is investigated. Coloured thin-film interference coatings on the reverse side of the collector cover gl ...

Demonstration of a 5x5 cm(2) self-tracking solar concentrator

Eric Tremblay, Volker Günter Zagolla

Solar concentration is using optics in order to minimize the amount of expensive photovoltaic cell material needed. For concentration factors higher than approximately 4, tracking the sun's position is needed to keep the focal spot on the solar cell. Based ...

Stationary solar concentrator delivering beyond the étendue law with homogeneous illumination

Marilyne Andersen, Boris Clément Karamata

We describe a concept for a novel stationary solar concentrator that relies on a new self-adaptive optical valve, non-imaging optics and the integrating sphere principle. Our analytical model reveals that this unique combination theoretically allows reachi ...

Demonstration and future potential of a self-tracking phase change actuator

Eric Tremblay, Volker Günter Zagolla

State-of-the-art concentrators use free-space optics to concentrate sunlight onto photovoltaic cells. To achieve high concentration factors it is necessary to track the sun's position. In current systems, mechanical actuators keep the focal spot in the sol ...

Reactively sputtered coatings on architectural glazing for coloured active solar thermal façades

Jean-Louis Scartezzini, Andreas Schueler, Martin Joly, Stefan Mertin, Virginie Hody-Le Caër

Covering a standard solar thermal collector with a coloured glazing, which is opaque to the human eye but highly transparent to solar energy, permits a perfect architectural integration of solar panels into glazed building façades. The colours are based on ...

Thermal solar collector with VO2 absorber coating and V1-xWxO2 thermochromic glazing – Temperature matching and triggering

Andreas Schueler, Rosendo Sanjines, Antonio Paone, Mario Geiger

Overheating is a common problem both with the use of active and passive solar energy in thermal solar energy systems and in highly glazed buildings, even in central European latitudes. In solar thermal collectors, the elevated temperatures occurring during ...

Self-tracking phase change concentrator device demonstrator

Eric Tremblay, Volker Günter Zagolla

Concentration photovoltaic systems uses free-space optics to concentrate sunlight onto photovoltaic cells, using mechanical trackers to accurately track the sun's position and keep the focal spot on the PV cell. We recently proposed and demonstrated a proo ...

Analytical model for ultra-thin body junctionless symmetric double gate MOSFETs in subthreshold regime

Jean-Michel Sallese, Farzan Jazaeri, Adil Koukab, Lucian Barbut

In this paper, we propose an approximate solution to solve the two dimensional potential distribution in ultra-thin body junctionless double gate MOSFET (JL DG MOSFET) operating in the subthreshold regime. Basically, we solved the 2D-Poisson equation along ...
