Hanwha SolarOne said the cell technology will optimise PV production processes

Chinese PV provider Hanwha SolarOne has announced the completed integration of new cell technology into its production processes. Through the implementation of the innovative technology, known as ‘Project EStarII,' Hanwha SolarOne said it is able to reduce silver paste consumption and optimise production processes to enhance PV efficiency and cost saving.

Jeong Eui Hong, chief technology officer at Hanwha SolarOne, said: "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. We plan to leverage this technology to gradually increase the cell efficiency of our multi-crystalline silicon wafers to more than 18.5 per cent by the end of 2015."

The news from Hanwha SolarOne follows other technology from Chinese solar companies contributing to increasing PV efficiency in November this year. Earlier this month, Chinese mono-and polycrystalline module manufacturer ZNSHINE SOLAR cost-effective solar noise reduction technology, which can increase PV power plant output by up to 30 per cent.

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

Hanwha SolarOne said all products made with the PV technology meet the company’s stringent cell requirements, as well as those for a number of international certifications.
