Solar Panels Efficiency Increased with Coating?

This could be a real breakthrough to increase solar panel efficiency.  We need more innovations like this to make solar and other alternative energy competitive with oil.

Coating helps solar panels soak up more of the sun

CHICAGO (Reuters) – A new type of reflective coating can make solar panels far more efficient, soaking up nearly all available sunlight from nearly any angle, U.S. researchers said on Monday.

Current solar panels — which convert energy from the sun into electricity — absorb only about two-thirds of available sunlight.

But surfaces treated with a coating developed at Rensselaer Polytechnic Institute in Troy, New York, can harvest 96.2 percent of sunlight.

“That is a tremendous savings,” Rensselaer’s Shawn-Yu Lin, whose study appears in the journal Optics Letters, said in a telephone interview.
