If 360° three-dimensional passivation

Is the "armor" of high-efficiency cells,

Then ultra-fine grid lines are the sharp "spears."

The grid lines on the surface of solar cells

Are like an "electrical grid" covering the cell wafers,

Responsible for collecting and exporting the current converted from light energy.

Traditional cells have relatively thick grid lines.

While stable, they also block

A large area of "land" that could absorb sunlight.

In contrast, the ultra-fine grid lines of TNC 3.0

Use high-precision processes

To thin the lines of this "electrical grid."

Compared to conventional TOPCon cells,

The light-blocking ratio of TNC 3.0's grid lines

Drops directly by 20%.

This means that

The sunlight previously blocked by the grid lines

Can now shine more directly onto the core functional areas of the cell wafers used for power generation.

It is equivalent to opening

A larger "skylight" for the power generation system,

Effectively expanding the light absorption area

And achieving "resource expansion" for power generation.

It can be said that

The ultra-fine grid line technology of Tongwei's TNC 3.0

Collaborates powerfully with 360° three-dimensional passivation.

The former, like a sharp "spear,"

Maximizes the capture of light energy and enhances efficiency through resource expansion.

The latter, like sturdy "armor,"

Provides all-around protection for the cells and reduces losses.

Working together,

They enable TNC 3.0 high-efficiency cells to "combine offense and defense,"

Fully unleashing the potential of photovoltaic power generation

And delivering superior power generation efficiency

Along with higher economic value.
