It is understood that TOPCon technology uses new passivation contact technology, and through the development and optimization of composite passivation materials and processes, it achieves comprehensive and efficient passivation of the battery surface, effectively suppressing carrier recombination loss. It also uses ultra-low optical parasitic absorption technology to effectively improve the battery's utilization of incident light. As well as new metallization technology, through innovative development of metal materials and refined electrode design, the photogenerated carrier collection efficiency is greatly improved.
As the next generation mainstream battery technology route, TOPCon platform technology continues to tap its efficiency potential, which is of vital significance to reducing the cost of electricity (LCOE) of photovoltaic power generation and promoting the green transformation of global energy.
