Diamond wire multi-wire cutting technology

2018-11-08

In the production workshop of the second phase of Inner Mongolia Photovoltaic Materials Co., Ltd., more than 100 single crystal silicon furnaces are all open and are being produced at full capacity. The drawn single crystal silicon rods are directly sent to the automated production line with Diamond Wire multi-wire cutting as the core technology, and processed into ultra-thin and high-efficiency single crystal silicon wafers for solar cells. This set of technology referred to as DW is completely independent by enterprises. R&D is at the leading level in the world.

The core technology of this project is called diamond line multi-line cutting. It is cut by the diamond wire as the cutting means. The resulting film is thinner, that is to say in the same More single crystal silicon wafers can be produced on a single crystal silicon material, and the photoelectric conversion rate is higher.” DW Phase I project under construction has put into operation 40 sets of operation equipment, which has formed more than 100% of design capacity and has stability. Production capacity. Marley said: "Central PV may be the only one in China that can be fully loaded and can continue to expand." This means that Inner Mongolia is not only fully operational in the face of the national PV industry downturn. And also withstood the pressure to continue to expand production capacity, looking at domestic PV companies, only Inner Mongolia Central did. This self-confidence of the enterprise comes from the technological innovation of the enterprise, which comes from the preferential policies of the city, the cost advantage of electricity price, and the support from the complete industrial chain of upstream and downstream.
