Dear Sir or Madam:

We are pleased to invite you to our stand at the International Green Energy Expo Korea 2010 from 7th to 9th April 2010 in EXCO, Daegu, Korea. At this exhibition, one of the most authoritative platforms for international cooperation and trade in the PV industry, we will be displaying our new innovative range of products along with our well established ones.

“CUSN’s Q3 2009 financial report confirmed that China Sunergy has developed a mono-crystalline high efficiency P-type solar cell with target conversion efficiency of over 19%. A test conducted in the third quarter by Fraunhofer Institute for Solar Energy Systems in Germany has shown the conversion efficiency of 19.04%.

For further details about from International Green Energy Expo Korea 2010, please refer to: http://www.energyexpo.co.kr/eng/sub01/sub01_01_1.asp

China Sunergy is a leading manufacturer of solar cell products in China. We manufacture solar cells from silicon wafers utilizing crystalline silicon solar cell technology to convert sunlight directly into electricity through a process known as the photovoltaic effect.

Currently we sell our solar cell products within China and to overseas module manufacturers and system integrators, who assemble our solar cells into solar modules and solar power systems for use in various markets.

As we treasure every opportunity to meet with our valued customer we would like to invite you to this exhibition. Your presence would be our great honor.
