01

Front & Back Sides- Busbarless

 

908 Technology

(Tongwei's independently developed 0BB technology)


Flexible connection and ultra-many solder wires

have improved the resistance to microcracks

 

The risk of cell microcracks is reduced by 30%

the shading area is reduced by 0.2%

and the current conduction is increased by 0.6%

 

Steel screen printing

 

Precise printing

It has reduced finger width by approximately 25%, with a maximum aspect ratio increase of 110% and a shading area decrease of 3.3%

effectively enhancing current collection capability

 

Screen printing

 

Ultra-fine lines

Full-aperture steel mesh to avoid obstructionachieving ultra-fine line width printing

Optimized form

With the uniform and flat grid line height, high-quality printing reduces resistance

 

 

02

Back Side - Optimized Optical Parasitic Absorption


Poly Tech


Bifaciality increased by 5-10%.

achieving an overall power generation gain of 0.67%.


Removing excess polysilicon between grid lines

and retains polysilicon in the slurry contact area

Simultaneously, it conducts passivation withnew materials

achieving superior cell passivation and contact performance

while reducing optical loss from long-wavelength light absorption by polysilicon


03

Cutting Edges - Efficiency Enhancement of Passivation


TPE Technology

 

Repair of damage and defects after cutting

It effectively repairs the cutting edges, enhancing cell efficiency by over 0.2%

 

Enhanced cell stability

The passivation layer protects the cell edges from environmental factors

such as moisture and oxidation, thereby extending the service life of the cell

 

Increased conversion efficiency

It repairs edge damage and reduces leakage current

enhancing the photoelectric conversion efficiency of the cell and increasing module power

 

04
