China Sunergy's High-Efficient Mono Cells Reach 20.26% Conversion Efficiency

China Sunergy Co., Ltd.

("China Sunergy" or "the Company"), a specialized solar cell and module manufacturer, today announced that its new generation of high-efficient mono-crystalline solar cells have reached 20.26% conversion efficiency in the pilot research and development ("R&D") line, and have received certification recently from the Fraunhofer Institute for Solar Energy Systems ISE ("Fraunhofer ISE"), the largest solar energy research institute in Europe. The new generation of high-efficient mono-crystalline solar cells combines the Company's Waratah and QSAR cell technology in a new design structure that enables it to achieve high conversion efficiency using normal wafers. The new conversion efficiency record of 20.26% was confirmed by Fraunhofer ISE as the leading level among all photovoltaic enterprises in China and has surpassed the benchmark of 20% mono-crystalline cells conversion efficiency set by the eight development guidelines issued by the State Council for China's photovoltaic industry in July 2013. The high-efficient mono-crystalline solar cells offer outstanding cost advantage and space reduction, making them ideal for rooftop applications. China Sunergy has installed high-efficient mono-crystalline solar cell production lines with the capacity of 70MW, and a corresponding module production line with the capacity of 15MW in its
