In the first phase of the project, super-large grain quasi-monocrystalline silicon ingots can be used for crystal seeding and ingot growth to obtain super-grained silicon ingots and processed to obtain quasi-monocrystalline silicon wafers for mass production. The characteristics of quasi-monocrystalline silicon wafers complete the research and development of the supporting battery technology. The average efficiency of the solar cell produced by the new process is over 17.2%, which is about 1% higher than that of the traditional polysilicon cell, and the highest efficiency is 18.2%.
