The first batch of products will be N-type materials. The project will start construction in March 2023 and enter commissioning and production in April 2024. On May 1, after 40 days of stand-alone debugging, single system debugging and system linkage debugging, the N-type material product of Yunnan Tongwei Phase II 200,000-ton high-purity crystalline silicon project was officially released and successfully came off the production line, achieving one-time start-up success. Yunnan Tongwei signed an investment agreement for the second phase of the 200,000-ton project on September 2, 2022. ； On March 21, 2023, the project actually started construction ； On March 21, 2024, it successfully entered the production transition stage. ； On May 1, 2024, the first batch of products will be officially released and reach the N-type electronic level. The successful rollout of Tongwei's second phase of 200,000 tons of N-type material products is not only a phased achievement in the development of Changning's green silicon material industry, but also a strong support for Tongwei to continue to build a "world-class clean energy operator." It is reported that after the second phase of Yunnan Tongwei's 200,000-ton high-purity crystalline silicon project is completed and put into operation, Yunnan Tongwei's high-purity crystalline silicon production capacity will reach 250,000 tons, becoming the largest single-unit production base in the world.
