China Sunergy Co. Ltd. has started mass production of its selective emitter cells after successfully commissioning recently arrived production equipment. The commercially produced selective emitter cells yielded an average efficiency rate of 17.5% during the first few days of mass production. Prior to starting mass production, China Sunergy achieved 18.2% conversion efficiency on some of its pilot runs in early November.
"I am delighted that we have managed to develop and commercialize these high-efficiency cells in less than a year and am confident that as we refocus our R&D resources, we will be able to achieve similar success with other high-efficiency cell products," says Dr. Jianhua Zhao, chief technology officer of China Sunergy.
"As we continue to optimize our selective emitter cell equipment and technology, I also believe that we should be able to achieve average efficiency rates of 18% on future commercial batches of these cells," he adds.
Complementing this news, China Sunergy has also announced that it has entered into various sales agreements with Canadian Solar Inc. to supply a total volume of 25 MW of solar cells for 2008. Under the agreements, the company will supply approximately 12 MW and 13 MW of solar cells to Canadian Solar in the first and second half of the year, respectively.
