Green energy from algae

(PhysOrg.com) -- Visitors to this year’s UK Royal Society Summer Exhibition will have a chance to discover how scientists from the University of Cambridge are studying ways to harness algae as a renewable energy source.

High-energy project in high desert

The sprawling solar installations gobbling up California's deserts have a new competitor, one that claims to generate more energy at lower costs while using less open space. Known as concentrator photovoltaics, or CPV, the ...

New method to make gallium arsenide solar cells

(PhysOrg.com) -- A new "transfer-printing" method of making light-sensitive semiconductors could make solar cells, night-vision cameras, and a range of other devices much more efficient, and could transform the solar industry.

New solar concentrator design (w/ Video)

A new solar concentrator design from an electrical engineering Ph.D. student at the University of California, San Diego could lead to solar concentrators that are less expensive and require fewer photovoltaic cells than existing ...

New Path To Solar Energy Via Solid-State Photovoltaics

(PhysOrg.com) -- Berkeley Lab researchers have found a new mechanism by which the photovoltaic effect can take place in semiconductor thin-films. This new path to energy production brightens the future for photovoltaic technology ...

New alloys key to efficient energy and lighting

A recent advance by Arizona State University researchers in developing nanowires could lead to more efficient photovoltaic cells for generating energy from sunlight, and to better light-emitting diodes (LEDs) that could replace ...

IBM develops promising contender for cheaper solar cells

(PhysOrg.com) -- Solar cells could make fossil fuels virtually redundant if they were cheaper, but their use of rare elements and complex manufacturing processes makes them expensive. Now IBM Research has developed a prototype ...

European space company wants solar power plant in space

(PhysOrg.com) -- EADS Astrium, Europe's biggest space company, plans to put a solar power satellite in orbit to demonstrate the collection of solar power in space and its transmission via infrared laser to provide electricity ...
