Based on the advantages of low silicon consumption per unit capacity, high cutting efficiency, low cost of auxiliary materials and thin silicon chip, the combination of diamond wire cutting polysilicon chip and black silicon technology is becoming the standard configuration of polysilicon battery. According to the 2018 itrpv data, the global market share of p-type polycrystalline battery is about 39% in 2025, which is equivalent to that of p-type monocrystalline battery. The continuous R & D and optimization of diamond wire cutting polysilicon technology and black silicon technology are particularly important for improving the performance of polycrystalline batteries and components and strengthening the market competitiveness.

Due to the influence of the new photovoltaic policy of 2018, the production capacity of Vajra line is seriously over, and the low-tech Vajra line enterprises will be eliminated. The enterprises with the ability to control the cost of Vajra line and ensure the quality will occupy a large market share after the industry recovery. Vajra wire cutting technology is developing to the direction of Vajra wire thin line, wafer and cutting process intelligence, which requires a higher quality Vajra wire to match with a higher performance cutting machine.

Because of the high reflectivity of silicon wafers, the surface of silicon wafers will be brighter and the damage layer will be shallower. However, additive technology, pretreatment technology or black silicon technology can solve the problem of diamond wire cutting polycrystalline silicon. The technology of diamond wire cutting polycrystal fluff making additive does not change the original equipment, increases the special additive and reduces the reflectivity to close to the routine. Black silicon technology can optimize the light trapping effect and improve the efficiency of polycrystalline solar cells. Black silicon technology is divided into dry black silicon technology and wet black silicon technology. Each has its own advantages. It has realized mass production and can be further upgraded and optimized.

According to the statistics of Asiatic consulting, China's black silicon production capacity has reached 25gw in the first half of 2018. The black silicon technology has great development potential. The production capacity can be doubled and the cost can be further reduced. The combination of black silicon and perc, Se and MWT technologies can further improve the mass production efficiency of the polycrystalline battery. The black silicon battery can also apply the technology of double-sided power generation, multi main grid, half cell and laminated tile module. With the progress of black silicon supporting conductive slurry and Metallization Technology, the battery Efficiency is expected to continue to improve. In addition, the black silicon technology can also be used in the single crystal silicon chip, especially the best technology choice of the ingot single crystal silicon chip.

The third diamond wire slicing and black silicon technology forum will be held in Changzhou, Jiangsu Province on September 12, 2018. The conference will discuss the prospect of photovoltaic industry and the competitiveness analysis of monocrystalline and polycrystalline batteries, the market prospect of diamond wire cutting technology and black silicon technology, the development of thin wire, thin film and intelligent diamond wire cutting technology, the upgrading and cost reduction direction of dry process black silicon and wet process black silicon technology, the application prospect of black silicon technology in monocrystalline silicon wafer and ingot single crystal, and the conductive slurry suitable for black silicon battery Combined application with metallization scheme, black silicon battery and other efficiency enhancing technologies, etc.
