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.
Ranked by production capacity, the world's top five polysilicon producers are all based in China, namely Yongxiang Co., Ltd., GCL-Poly Technology, Xinte Energy, Daqo New Energy, and Asia Silicon Industry.
By the end of 2023, the number of operational polysilicon manufacturers worldwide had increased to 25, including 16 in China and about 9 overseas. Looking at the production capacities of various companies in 2023, the number of companies with an annual production exceeding 10,000 tons increased from 16 in 2022 to 20.
Overseas polysilicon production is primarily concentrated in Germany, the United States, and Malaysia. However, due to electricity restrictions and high electricity costs in Europe and North America, the growth of overseas polysilicon production capacity has been relatively slow.
In 2004 eleven polysilicon plants worldwide had a total production capacity of only 29,150 metric tons – Chart: Bernreuter Research Wacker, Mitsubishi, Sumitomo Titanium and Hemlock already started to produce polysilicon on an industrial scale between 1959 and 1961; the rest followed suit between the mid-1970s and mid-1980s.
It is evident that China occupies a dominant position in the global supply of polysilicon. This is primarily due to Chinese polysilicon manufacturers having significant advantages in raw materials, electricity, and labor costs, along with continuous improvements in the quality of Chinese polysilicon products.
