40.8% efficient solar cell!
William Henning - Monday, September 29th, 2008 | 1:04PM (PT)


New record in solar cell efficiency

Mark Wanlass of the US Department of Energy's National Renewable Energy Laboratory invented an inverted solar cell, and his design was improved on by a team led by John Geisz.

The improved cell provided a 40.8% efficiency in converting light from the sun to electricity; mind you, the sunlight was concentrated 326-to-1.

If the cost of production can be reduced, such high efficiency may lead to solar power plants in desert areas that could produce great deal of power without requiring any fuel other than sunlight.

I sometimes hate solar energy, because my CASIO's G-SHOCK solar-powered watch sometimes blacks out due to lower battery level especially in winter and even sometimes on a hot summer night. May be I should use that improved cells in the future!!!!

I <3 solar power so much. My Dodge Durango gets 13MPG, so gas is a bitch to pay for. I really just wanna plant some of those solar cells on top of my car now.
