China Sunergy Co. announced it has received patent approval for its N-type cells from China’s State Intellectual Property Office. China Sunergy manufactures solar cells from silicon wafers utilizing crystalline silicon solar cell technology based in Nanjing. The approval from the State Intellectual Property Office covers a period of 20 years. China Sunergy has also submitted a patent application to SIPO for P-type selective emitter cell technology and is awaiting the potential approval in 2009.
Since the commencement of limited commercial production of selective emitter cells in early May, company officials say they have achieved an average conversion efficiency rate of great than 17 percent on their N-type cells. This compares with the average conversion efficiency rate of 15.9 percent that the company achieved on monocrystalline 125-millimeter cells in the second quarter of this year. China Sunergy is currently targeting to achieve more scalable commercial production of this higher-efficiency product on one of its existing six production lines during the third quarter of this year.
“Our strong new product pipeline, which will include P-type selective emitter cells and N-type cells, and the exciting progress in commercializing the former, is giving us confidence that we will be one of the technology leaders in the years ahead,” Tingxiu Lu, chairman and CEO of China Sunergy, said in a company statement. “Furthermore, this will also help us address the raw material supply tightness that the industry is experiencing at the moment.”
