SunPower Efficient PVs

SunPower Corporation has announced that their new A-300 crystalline-silicon solar cell converts over one fifth of the sunlight hitting it into electricity. The National Renewable Energy Laboratory has verified a

20.4% conversion efficiency for the 125-millimeter, single-crystal A-300 cell, making it likely to become the most efficient cost-per-watt solar cell in the industry. Currently manufacturing a pilot-scale line of the cell, SunPower anticipates beginning full-scale production next year.
