“HJT”

PERC, TOPCon, HJT Three technical performance, cost, process comparison!

1. Comparison of three battery technology potentials   So far, there are 3 technical routes, PERC battery is the most mainstream technical route accounting for 90% or more, and TOPCon and HJT are both on the rise.   Maximum theoretical efficiency: PERC battery is 24.5%; TOPCon is divide...
