Tongwei TNC 2.0

 Pioneering Green Solutions with Cutting-Edge Technology

Amid summer cicadas' chorus, after China's National College Entrance Examination

admission letters now traverse mountains and oceans

to reach aspiring students' hands.

In the context of

global energy transition

Tongwei TNC 2.0 modules excel with

908 Technology (Tongwei's proprietary 0BB technology)

steel screen printing

TPE technologies

and Poly Tech

With these four core technologies

Tongwei has demonstrated all-round excellence as a "top performer"

harnessing innovation to

become an all-aspect champion in efficiency evolution

redefining efficiency limit of PV modules

through technological breakthroughs

while receiving continuous "admission letters"

from global clients

01

908 technology

908 Technology (Tongwei's proprietary 0BB technology)

is a cornerstone of TNC 2.0's four core processes

featuring patented

busbar treatment & module interconnection technology

Tongwei 908 Technology: Flexible connection, ultra-many solder wires, and enhanced resistance to micro-cracks

It reduces the risk of micro-cracks in cells

decreases the light-shielding area

and enhances current conduction

Compared to traditional SMBB, 908 Technology focuses on

fewer busbars, reduced rigidity, lower stress

delivering superior overall power generation

02

TPE technology

Tongwei's TPE technology

developed over time

creates a barrier at the cutting edge to prevent charge recombination

thereby extending the lifespan of photogenerated carriers

and improving minority carrier lifetime, open-circuit voltage, and photoelectric conversion efficiency

The TPE technology from Tongwei optimizes sorting and scribing processes

to avoid damage risks associated with full-cell passivation and subsequent cutting

At the same time, passivated half-cells can be directly used for module encapsulation

reducing the complexity of subsequent processes

03

Poly Tech

Poly Tech technologies

removes localized poly layers on the back

enhancing the module's infrared light response

Modules utilizing Poly Tech technology

The cell efficiency exhibits significant improvement

Bifaciality is increased by 5-10 percentage points

with an overall power generation gain of 0.67%

The highest bifaciality at the technology research and development level can reach an industry-leading 88%

This record has been certified by Rheinland

Compared to conventional TOPCon modules in the market

the comprehensive power generation gain exceeds 0.67% (data source: Tongwei internal calculation)

Under identical installation conditions

especially in high-reflectance ground scenarios

the back-side power generation gain of TNC2.0 modules will be even more significant

04

Steel screen printing

with its ultra-fine grid lines

enhances light absorption on the cell surface

thereby improving electrical performance and cell conversion efficiency

TNC 2.0 modules Modules utilizing this technology

(compared to conventional SMBB modules)

Achieving a 25% reduction

of width of busbars

and a 3.3% decrease

of shading area

(Data source: Tongwei internal calculation)

Effectively improves current collection capability

With efficient performance of solid strength

empirical data validates competence

Tongwei TNC 2.0 modules

realized a 30-year power generation increase of over 0.5%

equivalent to an additional 330 million kilometers of range for electric vehicles

It also achieved a lower per-watt comprehensive energy cost

The BOS cost is reduced by 3.61 cents/W

and the LCOE is reduced by 1.65 cents/W

demonstrating the solid strength of "PV Top Performer" with real data

Note: Tongwei TNC 2.0 G12R 66 Module (650W)

Benchmarked against conventional modules (620W) in simulation model

Taking a 100MW Madrid (Spain) project as an example, with a DC/AC ratio of 1.2, using a 320kW string inverter

Leveraging the advancements in key technologies

Tongwei TNC 2.0 modules

combine robust foundation with continuous breakthroughs

delivering top-tier solutions

to the global clean energy market

With unprecedented efficiency gains, TNC 2.0 modules empower the energy transition
