What makes JA Solar’s N-type TOPCon technology unique?
JA Solar's N-type TOPCon technology differentiates itself through the following innovations:
Breakthrough in efficiency : Utilizing a low-doped boron front end and a localized poly structure on the back end, mass-produced modules achieve an efficiency of 24.8% (DeepBlue 5.0 series), exceeding the theoretical limit of 28.7%.
4.
Process optimization :
The innovative "crystal string" fine-gate interconnect technology reduces process complexity and cost.
4;
Compatible with PERC production lines, requiring only the addition of boron diffusion and thin film deposition equipment, making the modification process relatively simple.
3.
Performance advantages :
Bifacial power generation gain exceeds PERC cells by more than 3%, with a temperature coefficient of -0.30%/℃.
3;
The passivated contact structure on the back reduces metal recombination and improves open-circuit voltage.
