Utilization of Direct and Diffuse Sunlight in a Dye-Sensitized Solar Cell - Silicon Photovoltaic Hybrid Concentrator System
Michael Graetzel, Shaik Mohammed Zakeeruddin, Paul Liska
The concept of a tandem hybrid concentrator solar module was demonstrated from a dye-sensitized TiO2 solar cell (DSSCs) and a silicon p-n junction solar cell. The test system employed DSSC and Si cells with indoor AM1.5G efficiencies of 9.1 and 18.1%, resp ...
2011Ultra-Light Asymmetric Photovoltaic Sandwich Structures
This work evaluated the possibility of using silicon solar cells as load-carrying elements in composite sandwich structures. Such an ultra-light multifunctional structure is a new concept enabling weight, and thus energy, to be saved in high-tech applicati ...
Elsevier2009Simulation and Optimization of Heliostat Fields using Radiance and MOO fot the Design of a 300 MWth Central Receiver
This work discusses solar power towers and especially the simulation and optimization of heliostat fields. The technological stateof the art is given through typical characteristic values and dimensions of some existing central tower power plants such as t ...
2008Electrification of Isolated Areas by Interconnecting Renewable Sources (ERD Project): Lessons Learned
Jean-Claude Bolay, Benjamin Michelon
Researchers from Switzerland and Morocco undertook a joint project to develop a technique for producing electrical energy from renewable primary energy sources to supply small networks of isolated consumers. Specific attention was paid to sustainable devel ...
2008Design of a software tool for PV-system-specific lightning protection
Photovoltaic (PV) systems are often installed on rooftops or as freestanding systems with no higher surrounding structures. This is why they are often exposed to the influences of lightning which can severely damage these expensive systems. Lightning prote ...
2006Unbalanced DC-link voltage regulation in a back-to-back 3-level PWM converter for a doubly-fed induction motor/generator.
Jean-Jacques Simond, André Hodder, Alexander Schwery
An unbalanced DC-link voltage regulation strategy is proposed for a three-level voltage source inverter used in the rotor cascade of a double-fed asynchronous motor-generator. The major problem in determining the presence of the unbalanced component is inv ...
