n-TOPCon Solar Cell Smart Production Line

  Features  

· An ultra-thin silicon oxide layer and a doped polysilicon layer are prepared on the back of the battery, which together form a passivated contact structure, effectively reducing surface recombination.

· By optimizing the back metal contact structure, the photocurrent loss is reduced, resulting in a higher open-circuit voltage and a significant improvement in conversion efficiency.

· With the advancement of mass production, the investment cost of TOPCon battery production lines has been significantly reduced.

· Compared with PERC batteries, TOPCon batteries have advantages such as higher efficiency, higher bifaciality, lower attenuation, and lower temperature coefficient.

· TOPCon technology is quite mature, highly compatible with existing PERC production lines, and easy for production line upgrading, thus having become a mainstream mass production technology.
