Songci Mechatronics, a unit of China-based PV gear producer Wuxi Autowell, has unveiled a low-oxygen furnace resolution for the manufacturing of n-type monocrystalline wafers.
The brand new resolution is designed to satisfy the upper high quality necessities of n-type cells primarily based on tunnel oxide passivated contact (TOPCon) know-how, which calls for a excessive temperature course of, low resistivity, and low that oxygen content material.
“Songci’s SC-1600-LO₂ low-oxygen monocrystalline furnace is designed to take away oxygen impurities by matching the opening place of the furnace pipeline and the course of the fluid pipeline by thermal discipline course of simulation,” the producer stated in an announcement. “The software program management algorithm contains an oxygen management operate module that allows the oxygen removing operate with out affecting the crystal pulling.”
Songci Mechatronics claims that the brand new furnace can cut back the frequent subject of concentric circles in n-type wafers by 50% and obtain a discount in oxygen content material of greater than 24% in comparison with mainstream wafers, which, in in flip, leads to a 0.1% enhance in cell effectivity.
In 2021, Songci Mechatronics acquired orders from JA Photo voltaic and Yuze Semiconductor as a brand new provider of monocrystalline furnaces. In 2022, the corporate signed CNY 1.29 billion ($185.4 million) in new orders, up 667% year-on-year. The corporate stated it expects new orders to succeed in CNY2 billion by 2023.
