Lowell, Mass. – July 7, 2004 – Konarka Technologies, Inc., an innovator in developing and manufacturing breakthrough products that convert light to energy, announced today a significant investment from the European venture capital community as part of its recent $18 million Series C round of financing.

“Konarka is a global technology leader in the development of third generation solar cells. Its patent portfolio is solid, and its research and development capabilities are first class,” said Georg Furger, vice president, Portfolio Management, Credit Suisse Asset Management, who acts as an investment adviser to Prime New Energy. “The political conditions for solar energy are favorable in many parts of Europe, and we predict large, long-term market potential for the third generation of photovoltaics.
