Secondly, the self-developed diamond wire cutting silicon wafer is used. Compared with the traditional silicon carbide method, the productivity of a single device is greatly improved.
The surface cutting damage and TTV of the silicon wafer are greatly improved, which improves the conversion efficiency of the battery and reduces the fragmentation rate; Moreover, polyethylene glycol cutting fluid is no longer used, which greatly reduces the discharge of COD in the production process.
In addition, on the basis of G5 polycrystalline furnace, a new G6 thermal field was independently developed, which further improved the productivity of silicon wafers, and these efforts made Yu Hui sunny.
The leading position in the technical field of solar energy industry provides high-quality solar energy products for global customers and promotes the continuous progress of solar energy industry.
