Hanwha Solutions to set up TOPCon module production line, build EVA factory


Hanwha Solutions, a unit of Hanhwa Group, has revealed that it will set up a production line for solar modules based on tunnel oxide passivated contacts (TOPCon) technology and M10 wafers at its facility in Jincheon, in South Korea's Chungcheong province.

It said it will also develop other high-efficiency solar technologies, such as tandem and perovskite solar cells, but it did not provide any additional details. The move is part of a KRW 760 billion ($548.8 million) plan to expand its solar business in South Korea. The plan includes KRW 130 billion for its TOPCon line and R&D activities, a KRW 590 billion investment for the production of ethylene-vinyl acetate (EVA) for solar module backsheets, and KRW 41.7 billion for the production of EVA sheets. 

The company said it will set up EVA production in partnership with GS Energy, a unit of South Korean conglomerate GS Group, at the Yeosu Industrial Complex in Jeollanam province. The manufacturing facility will have an annual capacity of 300,000 tons.

“Through this joint venture, Hanwha Group's EVA production capacity, including Hanwha Solutions, will increase to a total of 920,000 tons,” the company said.

Hanwha Solutions recently agreed to buy a 16.67% stake in Norway-based polysilicon manufacturer REC Silicon ASA for $160.4 million. In the United States, REC Silicon owns and operates a polysilicon factory in Moses Lake, Washington, and another facility in Butte, Montana. Hanwha Solution also operates a 1.7 GW solar module factory in the United States and is currently considering the construction of a second factory there.
