Polycrystalline silicon is a capital-intensive industry. In the past, Taiwan's manufacturers of solar-grade polycrystalline silicon have been invested by Evergreen Chemical and Everlight Electronics' subsidiaries, i.e. "Fortune Solar", "Huaxin Group", and "Baldwin Energy", which is invested by CMC. However, due to the significant expansion of Chinese polysilicon manufacturers in 2015, coupled with the increase in production capacity of international polysilicon manufacturers such as OCI of South Korea, Tokuyama of the U.S., and REC of Norway, the supply of polysilicon materials far exceeded the demand, which ultimately led to the bankruptcy of FUJU in 2015, and the sale of BaoDe's plant and equipment to Evergreen Chemical Corporation (EGCC) in 2020. As a result, there are no major upstream manufacturers of polysilicon raw materials in Taiwan. In recent years, Taiwan manufacturers have shifted their main business areas to the "upstream and back-end" and "midstream" of the industrial chain, including silicon wafers, solar cells and solar cell modules, and their supply capacity is second only to China's, which accounts for about 15% of the global production capacity.
