(“JinkoSolar” or the “Company") (NYSE: JKS) a fast-growing, vertically-integrated solar power product manufacturer based in China, today announced the launch of a new research and development center to focus on improving conversion efficiency of solar cells and next generation photovoltaic technology.? With the new research and development center, JinkoSolar is targeting to increase the conversion efficiency rate to more than 18.6% for monocrystalline solar cells and more than 17.5% for multicrystalline solar cells by the end of 2011, compared with the current average efficiency rate of 18.1% and 16.8%, respectively. JinkoSolar will launch the first generation of its “Blue Cell” modules in the third quarter of the year.? The new modules will feature cell efficiency rate of more than 18.6% as a result of a number of research and development initiatives that will be rolled out by the Company’s new research and development center. Mr. ChaolinZha, Research and Development Technology Director of JinkoSolar, will lead the research and development center. Mr. Zha holds a PhD in Semiconductor Physics from Fudan University and completed post-doctoral works involving crystalline silicon solar cells and micro/nano-electronics at University of Notre Dame, Indiana, Norwegian University of Science and Technology in Norway and Royal Institute of Technology in Sweden.? Previously he worked for Shanghai Tomi Solar Technologies Corporation and has over four years of working experience in the PV industry and over 10 years of scientific research in crystalline silicon solar cells. Mr. Kangping Chen, CEO of JinkoSolar, said, “Mr. Zha has been with JinkoSolar for one year.? He has great experience in developing cutting edge photovoltaic technology. We are confident that he will play a significant role in leading our research and development efforts going forward.” The Company also announced today the resignation of Mr. Guoxiao Yao, Chief Technology Officer, for personal reasons. Mr. Kangping Chen said, “We appreciate Mr. Yao’s contribution to JinkoSolar. His guidance has helped us establish our research and development team and achieve significant improvements in our technological processes while maintaining our low-cost operations.?? With his help, we have built a solid foundation for the next stage in our research and development as we now expect to make significant improvements in the conversion efficiency of our products and in reducing non-silicon costs. We wish Mr. Yao great success in the future.” ?
