Tongwei TNC 3.0 Module

Its cells employ 360° 3D Passivation Technology

What else is special about this technology?

Let's keep exploring!


TNC 3.0 Module High Bifaciality

Not just the front side

Increasing back-side light absorption

Bringing more returns


Traditional TOPCon cells

Have a full layer of POLY polysilicon material on the back side

It's like building a house

On the shady side

You build a whole thick wall

Although the structural support of the house is ensured

It also blocks all the light and scenery outside the wall

Yet even on the shady side of a house

There is still plenty of scenery and light

Tongwei's POLY TECH technology

Has renovated the wall on the shady side

While retaining the load-bearing walls

that provide the structural strength of the house

All other wall areas have been removed

And replaced with floor-to-ceiling windows

This way, the house is ensured

to have sufficient structural strength

While also letting light flood into the rooms

Providing more emotional value

And generating more returns
