| New world record solar cell efficiency  SunPower Corp., a Silicon Valley-based manufacturer of high-efficiency solar cells, solar panels and solar systems, announced that it has produced a full-scale solar cell with a sunlight to electricity conversion efficiency of 24.2 percent at its manufacturing plant in the Philippines. This is a new world record, confirmed by the U.S. Department of Energy's National Renewable Energy Lab (NREL), for large area silicon wafers. "This new world record demonstrates SunPower's ability to extend our lead in manufacturing the world's highest efficiency solar cells," said Bill Mulligan, vice president of technology and development for SunPower. "Our patented and proprietary, high-efficiency solar cell technology drives down the cost of solar energy by increasing the energy production from each solar panel."Improved cell efficiency reduces the levelized cost of energy by increasing the energy production from each wafer manufactured into a SunPower solar cell. For the same reason, increased efficiency reduces the cost per watt and cost per kilowatt-hour for feedstock and materials, depreciation and other manufacturing expenses, installation time, land and system operations, and related maintenance. write your comments about the article :: © 2010 Construction News :: home page |
