SunPower Corporation has said that its Gen 3 solar cell technology that is currently under development has reached cell efficiencies of 23.4 percent using standard five-inch wafers. SunPower claims that this is a new world record for a large area solar cell.
“This is a step function increase from our 22 percent efficient Gen 2 technology, which has been in mass production since last year,” said Tom Werner, CEO of SunPower Corp. “Credit for this achievement goes to our world- class research and development team led by Dick Swanson and Bill Mulligan, as well as to our talented engineering group.”
“We are pleased to have demonstrated early success with our Gen 3 technology,” said Bill Mulligan, Vice President of technology and development at SunPower Corporation. “This record efficiency solar cell, which is expected to be commercially available in approximately two years, extends SunPower's leadership position and is a key component of our plan to reduce system cost by 50 percent by the year 2012.”
The company expects its Gen 3 solar cell technology to enter mass production in 2 years. Currently, its Gen 2 technology has cell efficiencies of 22 percent.
