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 ...

A Passive Louver-Based Daylighting System

Marilyne Andersen

A daylighting system for use in a building including a louver array having a first longitudinal element, and a second longitudinal element spaced therefrom. At least one of the first and second elements has an asymmetrical profile, each of the first and se ...

Modelling of the receiver transient flux distribution due to cloud passages on a solar tower thermal power plant

Daniel Favrat, Germain Augsburger

As more and more solar tower thermal power plants are being operated, built or planned, effort is put both on the development and research to bring costs down and increase the plant efficiency. In those plants, the central receiver is one of the key compon ...

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 ...

Thermal phase change actuator for self-tracking solar concentration

Damien Claude-Marie Loterie

We present a proof of principle demonstration of a reversible in-plane actuator activated by focused sunlight, and describe a concept for its use as a self-tracking mechanism in a planar solar concentrator. By actuating at the location of focused sunlight ...

Embedded microstructures for daylighting and seasonal thermal control

Jean-Louis Scartezzini, Yves Leterrier, Andreas Schueler, André Gabriel Kostro, Mario Geiger, Marina Aymara González Lazo, Nicolas Jolissaint

A novel concept for an advanced fenestration system was studied and samples were produced to demonstrate the feasibility. The resulting novel glazing will combine the functions of daylighting, glare protection, and seasonal thermal control. Coated microstr ...

Self-assembled photosystem-I biophotovoltaics on nanostructured TiO2 and ZnO

Michael Graetzel, Mohammad Khaja Nazeeruddin

The abundant pigment-protein membrane complex photosystem-I (PS-I) is at the heart of the Earth's energy cycle. It is the central molecule in the "Z-scheme'' of photosynthesis, converting sunlight into the chemical energy of life. Commandeering this intric ...

On-site performance of electrochromic glazings coupled to an anidolic daylighting system

Jean-Louis Scartezzini, Nicolas Morel, Jessen Page

This work takes benefit from two advanced building technologies through the integration of an anidolic daylighting system and an electro-chromic glazing in a building facade for achieving an optimal control of the daylight flux entering in an office room. ...

A new concept for a low-cost Earth sensor: Imaging oxygen airglow with arrays of single photon detectors

Edoardo Charbon, Herbert Shea, Cristiano Niclass, Noémy Scheidegger

This paper presents a novel concept for a compact low-cost Earth sensor based on imaging atmospheric oxygen emission at 762nm using arrays of single photon avalanche diodes (SPADs). In both nighttime and daytime there is continuous emission at 762nm due to ...
