MBB: “Multi-busbar” or “Multi-wire” is the natural next evolution of the cell-stringing technology, which supports the constant increase in a PV module’s peak power.
MBB Technology brings significant benefits at different levels: production, module efficiency and reliability, apart from the lower series resistance, the round-shaped busbar,it increases the scattering effect towards the cell surface for higher cell absorption.
Another advantage in terms of reliability is the lower impact of possible microcracks that might occur during the modules’ lifetime, thanks to the shorter distance between the adjacent wires.
Multi-busbar reduces current loss
The amount of incident light is increased with new welding wire
Multi-busbar forms shorter current path
(Impact of micro cracks on power generation is reduced)
