Silicon Wafer Production And Specifications

Announcement of discontinuation of production of photovoltaic silicon panels

REC Silicon announced it is ceasing production at its Moses Lake, Washington facility that produced polysilicon used in solar manufacturing. The reason given for the shutdown was the inability to “improve the level of some key impurities,” according to a press release. Tongwei will halt output of high-purity polysilicon from the. . On December 24, two leading polysilicon enterprises in the PV industry—Tongwei Co. and Daqo New Energy—successively issued two production cut announcements. This news, in the context of the PV industry having long advocated for "anti-cut-throat competition," is nothing short of a "bombshell. China's leading polysilicon firms are reportedly considering shutting down one third of the country's polysilicon capacity and restructuring the sector, following years of overcapacity. . REC Silicon, a Norwegian polysilicon supplier, recently announced the cessation of production at its polysilicon plant in Moses Lake, Washington, USA.
