World’s Top 4 Polysilicon Manufacturers in 2022 will be Chinese

The world’s four largest polysilicon manufacturers in 2022 will all be based out in China, as predicted by Bernreuter Research in its latest ranking of top ten producers of polysilicon.

Germany-based Wacker Chemie, which became the global number one after opening its third polysilicon plant in the US state of Tennessee in 2016, lost its top position to Tongwei in 2020. The Chinese high flyer was still number nine in 2016 before it started an ambitious expansion program. With three production locations in Sichuan province, Inner Mongolia and Yunnan province, Tongwei will reach a total capacity of nearly 200,000 metric tons (MT) by the end of this year and likely 300,000 MT in 2023.

According to the production estimates of Bernreuter Research provided in The Polysilicon Market Outlook 2024, Wacker slid to the second rank in 2020, closely followed by China-based Daqo New Energy, which ousted OCI from the third place. After shutting down its solar-grade polysilicon operations in South Korea last year, OCI dropped to number seven in the ranking.

Wacker is still the world’s largest manufacturer of electronic-grade polysilicon for the semiconductor industry and is aiming to gain further market share in this smaller segment. In contrast to its rapidly expanding Chinese competitors, however, the quality leader has no intention to increase its solar-grade capacity beyond continuous debottlenecking. “We are certainly not interested in building incredible, new capacities,” said CEO Rudolf Staudigl in the conference call about his company’s first-quarter results on April 30.

Consequently, Wacker will be overtaken by three more Chinese manufacturers and fall back to number five in 2022, predicts Bernreuter Research.

Commenting on the predictions, Johannes Bernreuter, head of Bernreuter Research and author of the Polysilicon Market Outlook 2024, said “the rise of China-based players in our ranking is exemplary for the increasing dominance of the Chinese polysilicon industry.” He added “China’s share in the global solar-grade polysilicon output will approach 90 per cent in the coming years.”

Three aspirants for the top four spots in 2022 – GCL-Poly, Daqo and Xinte Energy – are running factories with very low-cost electricity from coal-fired power plants in the Xinjiang Uyghur autonomous region in northwestern China. The area has come under scrutiny after reports surfaced on the widespread use of forced labor there, the report highlighted.

“These reports should be a wake-up call for western governments. If their countries don’t want to become almost completely dependent on solar products from China for the transition to renewable energy, they have to implement an effective and long overdue industrial policy for a non-Chinese solar supply chain, in particular for ingot and wafer manufacturing,” commented Bernreuter.

He also said “low-cost and renewable hydropower in the northwestern USA, Canada, Norway and Malaysia offers them the chance to fuel an alternative supply chain without forced labor and a high carbon footprint.”
