Plasmonic device converts light into electricity

(PhysOrg.com) -- While the most common device for converting light into electricity may be photovoltaic (PV) solar cells, a variety of other devices can perform the same light-to-electricity conversion, such as solar-thermal ...

Drinking water from air humidity

Cracks permeate the dried-out desert ground, the landscape bears testimony to the lack of water. But even here, where there are no lakes, rivers or groundwater, considerable quantities of water are stored in the air. In the ...

Yale engineer to build 'hot' solar cells

Associate professor of electrical engineering Minjoo Larry Lee has been awarded $2,540,000 to develop dual-junction solar cells that can operate efficiently at extreme temperatures above 750 degrees Fahrenheit. In addition ...

Solar panels that protect themselves in high temperatures

Smart materials are revolutionizing solar thermal collectors. A team of researchers from EPFL has developed a coating that is capable of absorbing heat as well as repelling it. Invisible to the naked eye, this process particularly ...

Green jobs grow slowly

Last year, Randy Hagen, president of Solar Skies Mfg in Starbuck, Minn., laid off four of his 14 workers after orders stalled for the rooftop solar collectors he makes. Government rebates promised last year under the Obama ...

Heating with the sun

Solar-Active-Houses heat themselves using heat collectors and water tanks. However, no one had conducted an objective assessment of how efficiently they do so. Fraunhofer researchers put some of these solar houses to the ...

Supersonic electrons could produce future solar fuel

Researchers from institutions including Lund University have taken a step closer to producing solar fuel using artificial photosynthesis. In a new study, they have successfully tracked the electrons' rapid transit through ...

New designs for smarter buildings

After two years of design, experimentation, fund-raising and building, the University of Arizona's Solar Decathlon team has completed construction of its 800-square-foot solar-powered house on the National Mall in Washington, ...
