Busbar is kind of solar ribbon, which is soldered directly onto silicon bulk to interconnect other cells. The more busbar in single cell, the less power loss, and also the less risk to produce the micro crack.
What is the SMBB Technology?
Firstly, MBB is the short name of Multiple Busbar, and now Jinko use 9 MBB at least for their N-type panels such as Jinko 370W N-type series.
Secondly, SMBB is meaning of Super MBB, which has up to 16 MBB such as Jinko 470W N-type series.
Of course, Jinko 440W as the best P type panels, it also has 10 MBB and circular ribbon.
The advantages of SMBB technology
· Less shadowing in the cell because there are thinner “power lines”.
· Shorter transport paths of the electrons because more lines are available.
· Less transport resistance because shorter paths are created.
· Less ohmic losses such as heat because the cell heats up less.
When more busbars are used, the power loss of the module decreases exponentially. The Tiger Neo series uses 16 busbars, so this energy loss is no longer significant.
By using more busbars, Jinko reduces shading, shortens transport distances, and reduces resistance in modules.
With the new Jinko Tiger Neo series, Jinko provides durable N-type cell modules equipped with advanced TOPCon technology in N-type.
