Compared with international advanced levels, the gaps in industrialization among domestic polysilicon producers are mainly reflected in the following aspects: 1. Low production capacity, with a prominent supply-demand imbalance. In 2005, the operating rate of companies producing monocrystalline silicon for solar energy use in China was between 20% and 30%, while that of companies producing such silicon for semiconductor applications was between 80% and 90%. Full-capacity production was not possible, and polycrystalline silicon technology and the related market remained in the hands of a few manufacturers in the United States, Japan, and Germany, which severely hindered the development of China’s industry. 2. The production scale is small; the currently recognized minimum economic scale is 1,000 tons per year, with the optimal economic scale being 2,500 tons per year. However, China’s polysilicon producers are still far from reaching these scales at present. 3. The processing equipment is outdated, resulting in high consumption of materials and electricity for similar products, as well as numerous issues related to waste generation. Compared to international standards, domestic polysilicon production has more than double the material and energy consumption, making the product costs uncompetitive. 4. The reliability, advancement, maturity of the thousand-ton-class process and equipment technologies, as well as the compatibility among various subsystems, all require verification through actual production operations, and further improvement is needed. 5. Domestic polysilicon manufacturers lack strong technological innovation capabilities, with insufficient investment in basic research; in particular, their ability to develop and manufacture custom equipment is poor. 6. Local governments and enterprises investing in polysilicon projects pose the risk of low-level redundant construction.
