Hanwha SolarOne Enhances Production with New Cell Technology

Hanwha SolarOne Co. Ltd. (the “Company”, or “Hanwha SolarOne”), a global photovoltaic provider of cost-competitive, high-quality solar photovoltaic modules, today announced the completed integration of new cell technology into its production processes. Through the implementation of this innovative new technology, known internally as ‘Project EStarII,’ Hanwha SolarOne is able to reduce silver paste consumption and optimize production processes to enhance efficiency and cost saving.

“This is truly a production milestone for Hanwha SolarOne. With this new technology, we are now able to produce world-class solar cells at competitive costs,” said Jeong Eui Hong, Chief Technology Officer at Hanwha SolarOne. “We plan to leverage this technology to gradually increase the cell efficiency of our multi-crystalline silicon wafers to more than 18.5 percent by the end of 2015.”

According to Hanwha SolarOne’s internal assessments, the new cell technology dramatically improves production capabilities. Products manufactured with the new technology are on average 0.2 to 0.25 percent more efficient, with module power gains of 3W to 5W on average. Moreover, this new technology reduces silver paste consumption by approximately 45 percent during production.

All products made with this cutting-edge technology meet Hanwha SolarOne’s stringent cell requirements as well as those for a number of international certifications.
