Sharp has developed a crystalline Si solar cell prototype with a cell conversion efficiency of 20%, aiming for mass production in 2010. The company claims its product will be the most efficient residential crystalline silicon solar cell available.
An unnamed American manufacturer has been contacted in order to procure enough polycrystalline Si when commercialization starts. Sharp has chosen solar energy has one of the main pillars in its future business strategy.

…conversion efficiency of 20%…in 2010.
Lame.
Commercial solar cells, usually made from silicon, are only about 40 to 50 percent efficient at converting sunlight directly into electricity.
Oh, wait, it’s “residential”.
Still lame. And too late…
Aren’t we all waiting to hear the conversion efficiency of black silicon anyway, which will, presumably blow traditional efficiencies away without adversely increasing production costs? Or did I miss something?
