Top 10 Ranking of world’s largest Polysilicon manufacturers
Ranking of the world’s largest polysilicon manufacturers places Tongwei Co., Ltd. (China) at number one. The top ten ranking of polysilicon manufacturers is based on the actual output in 2020, not as per the production capacity. Seven of the top ten are based in China. The list of the top ten rank holders is provided here.
- Tongwei Co., Ltd. (China)
Sichuan Yongxiang, Tongwei’s subsidiary began the production of polysilicon in Leshan, Sichuan province with a small capacity of 1,000 MT and a bold target of 10,000 MT in 2008. With an expansion to 20,000 MT in 2017, Tongwei set up two new plants for low-cost, high-purity polysilicon in Leshan and Baotou, Inner Mongolia
- Wacker Chemie AG – Germany/USA
After Wacker’s strong expansion of solar-grade capacity at the factory in Burghausen, two additional polysilicon plants were opened with a capacity of 20,000 MT each in Nünchritz, Germany and Charleston, USA in 2011 and 2016. Consequently, it moved from second to first rank in 2016 but was slipped back by Tongwei in 2020.
- Daqo New Energy Corp. (China)
The company built a new polysilicon plant with a capacity of 5,000 MT in Shihezi, Xinjiang during the oversupply phase in 2011/2012. The company expanded gradually and reached 80,000 MT in 2018/2019. The company is amongst the lowest cost polysilicon producers in the world.
- GCL-Poly Energy Holdings Ltd. (China)
Hong Kong-headquartered company covers the complete solar value chain through controlling shares in GCL-Poly Energy Holdings (polysilicon, wafers), GCL System Integration Technology (solar cells and modules, PV system integration) and GCL-Poly’s subsidiary GCL New Energy Holdings (solar farms).
- Xinte Energy Co., Ltd. (China)
The company became China’s second-largest polysilicon manufacturer after a capacity leap from 3,000 to 17,000 MT in 2013. It benefits from a captive, coal-fired power plant with extremely low electricity costs.
- Xinjiang East Hope New Energy Co., Ltd. (China)
The first production line of the company which started up in 2017, has a nominal capacity of 15,000 MT, but an effective capacity of 20,000 MT. The second 20,000 MT line followed in 2018. East Hope originally planned the next expansion step for 2020. As per reports, it is aiming at 70,000 MT in 2021. The company has extremely low electricity costs.
- OCI Company Ltd. (South Korea/Malaysia)
The company continues to run its low-cost 30,000 MT plant in Malaysia and to produce a small amount of electronic grade in Gunsan.
- Asia Silicon (Qinghai) Co., Ltd. (China)
The company started production with a capacity of 1,000 MT in 2008. In 2015, it took a leap from 5,000 MT to 15,000 MT and further expanded to 20,000 MT in 2018. It benefits from low-cost electricity fed by hydropower.
- Hemlock Semiconductor Operations LLC (USA)
The U.S. based private company was the polysilicon market leader from 1994 through 2011. The company is still the world’s second-largest producer of electronic-grade polysilicon.
- Inner Mongolia Dongli Photovoltaic Electronics Co., Ltd. (China)
The company’s polysilicon quality is largely only multi grade. Its capacity doubled to 12,000 MT in 2019. The company became the tenth largest Polysilicon Manufacturer in 2020.
