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, Stefan Mertin, Martin Joly, 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, Mario Geiger, Antonio Paone

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 ...

Thermo-economic optimisation of large solar tower power plants

Germain Augsburger

Given the growing number of solar tower power plants in operation, under construction and under planning, the assessment and the optimisation of their performance are required both at the energy level and the economic level. In other words, the same way as ...

Efficiency of a micro-bubble reflector based, self-adaptive waveguide solar concentrator

Eric Tremblay, Volker Günter Zagolla

State of the art solar concentrators use free-space, non-imaging optics to concentrate sunlight. Mechanical actuators keep the focal spot on a small solar cell by tracking the sun's position. Planar concentrators emerged recently that employ a waveguide sl ...
