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

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 ...

Self-tracking planar concentrator using a solar actuated phase-change mechanism

Christophe Moser, Volker Günter Zagolla, Damien Claude-Marie Loterie

In this paper we discuss optical considerations and present design simulation results for a self-tracking (passive) solar concentrator. The self-tracking mechanism uses a reversible in-plane paraffin thermal actuator to couple short-wavelength light into a ...

Early design phase evaluation of urban solar potential: Insights from the analysis of six projects

Marilyne Andersen, Émilie Nault

This paper presents the outcome of a study based on the early-stage analysis of six virtual urban-scale designs located in Bern, Switzerland. A preliminary solar potential evaluation methodology is devised, inspired by previous studies, to allow the compar ...

Quantification and Modeling of Wet-Antenna Attenuation for Commercial Microwave Links

Alexis Berne, Marc Schleiss

Data from a new experimental setup deployed in Dübendorf (Switzerland) are used to quantify and model the magnitude and dynamics of the wet-antenna attenuation (WAA) affecting a 1.85-km commercial microwave link at 38 GHz. The results show that the WAA exh ...

Photoelectrochemical Tandem Cells for Solar Water Splitting

Kevin Sivula, Mathieu Steven Prévot

In order to be economically competitive with simple "brute force" (i.e., PV + electrolyzer) strategies or the production of promising solar fuels, like H-2, from fossil fuels, a practical photoelectrochemical device must optimize cost, longevity, and perfo ...
