ABC (All Back Contact) Explained
ABC (All Back Contact) is the back-contact cell technology developed by Aiko. Like other back-contact designs, it places all the electrical contacts on the rear of the cell, so no busbars shade the front. This lifts efficiency to around 23 to 24 percent and gives a clean all-black appearance. ABC competes with Maxeon's IBC and LONGi's HPBC. All three are back-contact approaches built on N-type silicon, differing mainly in manufacturing method and cost.
