Portland City Storage: 175,000 SF Of Solar Cells

by Justin Thomas •

This complex is a storage facility to be built by Portland City Storage on the east bank of the Willamette River in Portland. It will have a glass tower rising more than 22 stories and enclosing a giant mechanical arm capable of lifting 40,000 pounds (to conserve valuable riverfront land).

Honda’s Silcion-Free Solar Cells

by Justin Thomas •

Honda has begun selling new thin-film solar cells in Japan. The solar cells are made with a compound of copper, indium, gallium and selenium (CIGS), rather than the conventional silicon. The cells are said to be “greener” because there is less carbon dioxide generated during their production. Some pundits believe that CIGS cells may become the low cost photovoltaic cell …

Aquarius Tower To Integrate Wind Turbines, Solar Cells

by Justin Thomas •

The Aquarius Tower will have wind turbines and a solar roof cleverly incorporated into its design. It will become one of the few buildings in the U.S. to incorporate such energy generating features. The tower is a proposed 38-story, 240,000-square-foot condominium complex that will be located across from the Georgia Aquarium, in Atlanta. It will also feature a robotic parking …

New Plastic Solar Cells Mimic The Veins In Tree Leaves

by Justin Thomas •

Researchers at Wake Forest University have announced they they have created plastic solar cells with an efficiency of 6%. Researchers say that have achieved record efficiency for organic or flexible, plastic solar cells by creating “nano-filaments” within light absorbing plastic, similar to the veins in tree leaves. This allows for the use of thicker absorbing layers in the devices, which …

Flexible Solar Cells: SolarRolls by Bruton

by Justin Thomas •

Brunton makes a range of flexible solar cells they call SolarRolls. These weather-proof solar cells can be rolled up quite tightly, and attached to a backpack. Seen here is a 14W model — it produces DC power even during low light conditions. SolarRolls come with a range of plugs, including a standard car lighter socket. They can also be attached …

New 3D Solar Cells Created

by Justin Thomas •

Recently, we featured some intriguing spherical solar cells from Japan. But now there’s an announcement that unique 3D solar cells have been created using nanotubes. The 3D solar cells capture photons from sunlight using an array of miniature “tower” structures that resemble high-rise buildings in a city street grid. The tower structures, which are about 100 microns tall, 40 microns …

New Biofuel Cells: Electricity From Hydrogen and Thin Air

by Justin Thomas •

Science Daily reports that British scientists have developed a “biofuel cell” that generates electricity from air spike with small amounts of hydrogen. These cells are an inexpensive, renewable alternative to “fuel cells” that have been closely associated with the “hydrogen economy”. At a recent meeting of the American Chemical Society, Fraser Armstrong, described how his research group at Oxford University …
