MBB/SMBB/0BB RIBBONS

Multi Bus Bar (MBB) and Super Multi Bus Bar (SMBB) use busbars are manufactured in circular cross-section and smaller diameter to lessen shadowing and resistance loss.  This helps to reduced the use of silver paste and an increase in overall power

0BB Ribbons are manufactured using cutting-edge technology that attached the ribbon directly to the fingers, reducing the amount of silver used and enhancing current collection.

Compared to SMBB technology, the 0BB wire diameter is lowered to 0.2 mm or smaller. This wire diameter reduction improves conductivity, reduces shadowing, and boosts the solar module power.
