New Solar Farm That Generates Electricity Even After Sunset

The new solar farm will be based on the use of 17,500 large mirrors called heliostats which will be arrayed in a circle around a 538-foot concrete tower. Each one will measures between 24 - 28 feet, being attached to 12-foot pedestals.

Mirror-Based Solar Device as Cheap as Coal-Burning Electric Power Plants

Sharp Releases 450mW Solar Cell Module for Cellphones

Sharp Corp. has announced the development of an improved solar cell module for cellphones at Green Device 2009, a trade show that will be open to the public from Oct 28 to 30, 2009, at Pacifico Yokohama, Yokohama City, Japan.

Optical Fiber Solar Cells: Cheap, Flexible, Six Times More Efficient

Georgia Tech researchers have developed a system that uses dye-sensitized (Grätzel) solar cells wrapped around optical fibers to increase their overall efficiency, since it's known Grätzel cells are not very efficient. The fiber solar cells they obtained are 6 times more efficient than zinc-oxide solar cells having the same area.
