Domestic PV companies release new resin diamond cutting lines

During the SNEC exhibition, one of the largest PV companies in China, Yanhui Sunshine Group (NYSE: SOL), released its latest technology research and development products in the global market on the 17th - resin diamond cutting line , Virtus ® new components. The new technology products of Resin Diamond's resin diamond cutting line and Virtus ® new module are not only the symbol of Suihui Sunshine's leading the photovoltaic industry with technological innovation, but also an important measure for its implementation of differentiated strategy. Resin diamond cutting line technology is a new manufacturing technology in the photovoltaic industry. Compared with the traditional silicon carbide method, the resin diamond cutting line greatly increases the productivity of a single device; the surface damage of the silicon wafer and the TTV are greatly improved, and the improvement is made. The conversion efficiency of the battery and the fragmentation rate are reduced; at the same time, the resin diamond cutting line no longer uses the polyethylene glycol cutting fluid, which greatly reduces the COD emission during the production process, and reduces the COD (chemical oxygen demand) emission by 60%. At the same time, the conversion efficiency of the solar cell is increased by 0.1%. The new Virtus ® component is another new technology product released on the same day, which is based on VIRTUS's new silicon wafer manufacturing components. It represents the development direction of the photovoltaic industry in the recent period, found between polycrystalline and single crystal. The best balance of benefits, not only the advantages of quality and efficiency, but also the price advantage. Zheng Zhidong, senior vice president of Sunshine Sunshine, said that Qihui Sunshine is the earliest enterprise in the industry to develop single crystal components. Although the current wind industry and the homogenization phenomenon are serious, the technology of Qihui has always been in a leading position. Future monocrystalline modules will become an important industry trend. Virtus ® can increase the average cell conversion efficiency of conventional polysilicon wafers from about 16.5% to more than 18.2%, and the module efficiency is close to and exceeds that of general single crystal components. Virtus ® is much lower than single crystal in terms of energy consumption or manufacturing costs, helping downstream PV companies reduce their overall investment and increase their return on investment. The release of the resin diamond cutting line and the new Virtus ® component is the first time that the company has launched a major product for the market since the European debt crisis. Li Xianshou, CEO of Yanhui Sunshine, said at the press conference that the increase in the launch of new products reflects the continued investment and continuous improvement of Yanhui Sunshine in research and development, and on the other hand, it shows the future market trend of Yanhui Sunshine. confidence. "With the gradual recovery of major market economies such as Europe and the United States, and the recovery of the domestic real economy, Sui Hui Sunshine is preparing to capture the opportunities of the future market."
