Tongwei TNC 3.0 Module

Its cells employ 360° three-dimensional passivation technology

What else is special about this technology?

Let's keep exploring!

360° Three-Dimensional Passivation Technology

Not only addresses front and back issues

but also targets side defect problems

Achieving a "full-wrap" protection effect

Conventional cells are produced as full-size wafers

However, the current market's

mainstream modules are half-cut or multi-cut modules

In other words

after module manufacturers receive the cells

they still need to cut each cell in half or even more

And during the cutting process

damage is generated at the cut edges of the cells

Just like cutting a cream cake in half

the cut sides will have many air pockets

with no cream

This causes the full-size produced

cells to have very high efficiency

but when used in modules

the half-cut cell efficiency drops significantly

Tongwei TNC 3.0 adopts TPE technology

After cutting the cell "cake"

it applies a layer of "cream" on the sides

Filling in the air pockets on the "cake" surface

for repair

This method reduces the situation where

electrons generated in the cells

run to the sides

and fall into "pits"

Achieving a "current-conserving" effect

Ensuring more electricity can be output to the outside of the module
