The silicon wafers
Scale: In 2017, the production of silicon wafers in China is about 18.8 billipn pieces, or 87.6GW,
accounting for 83% of the global production of silicon chips, including about 6 billion pieces of single crystal silicon.
Technology: the diamond line is universal in the field of single crystal, and in the second half of the year the poly crystal field also began to spread rapidly.
Cost: the use of the diamongd line and battery efficiency increased, the silicon consumption decreased greatly, and the non-silicon cost decreased significantly.
