The advantages of CZ single crystal are single crystal orientation, low defects, and high battery efficiency; the disadvantages are small single feed, complex operation, and high cost. The advantages of polycrystalline silicon ingots are large feed, simple operation, and low cost; the disadvantages are the presence of grain boundaries and various defects, and the battery conversion efficiency is lower than that of single crystal.
The R&D and production team, led by Dr. Huang Xinming, General Manager of Donghai JA Solar, has completed the development of monocrystalline silicon ingot technology. This technology is used to produce (100) crystal orientation seed crystals and ingots, obtain ultra-large grain silicon ingots, and process them into quasi-monocrystalline silicon wafers to achieve mass production. This technology is highly operable, easy to promote, stable and reliable. The product performance has the advantages of monocrystalline silicon, and the oxygen content is lower than that of CZ single crystals, which has a strong cost advantage compared to monocrystalline silicon wafers. Its production process is characterized by low energy consumption (average 7kWh/h), low cost and environmental friendliness.
While completing the research and development and production of quasi-monocrystalline silicon ingot technology, the project also participated in the research and development of supporting battery technology in combination with the characteristics of quasi-monocrystalline silicon wafers. The average efficiency of the battery cells produced using the new process reached more than 17.2%, which is about 1% higher than the traditional polycrystalline silicon cells, and the highest efficiency reached 18.3%. The total power of the battery of a single ingot is 2000-4000W higher. Compared with polycrystalline silicon ingots, the use of single crystal ingot technology will increase the annual production capacity of each ingot furnace by 0.3-0.4MW, and this technology will bring about an increase in benefits of about 30-40 million yuan per furnace.
In addition, they have successfully developed a number of core technologies and applied for three national invention patents and one utility model patent. The Lianyungang Science and Technology Bureau organized relevant experts to appraise the technology on March 19 and believed that the achievement reached the international leading level.
