Silicon produced in our country
Thread Content
To promote the industrialization of photovoltaics, our country has introduced many favorable policies... I would like to know how to produce high-purity silicon? Using that country’s craftsmanship?
If you don’t even know this, it’s really not right to criticize you; but as a worker in the photovoltaic industry, you should know this, right? It’s something very basic. The Renewable Energy Act of 2005, technologies from Germany, Japan, and the United States. Germany’s improved Siemens technology, Japan’s silane method, and some metallurgical methods.
Generally, the modified Siemens method is used, as it is relatively more mature in terms of technology!
If you want to get into the polysilicon industry now, it’s best to do more research. The new manufacturing processes are relatively simple, require less initial investment, result in lower production costs, and cause less pollution. Although the modified Siemens method is relatively mature, it requires a large initial investment, causes significant pollution, and results in high production costs.
Improved Siemens technology is indeed the most widely used at present
