Bifacial Modules

Core Advantages
Additional Power Generation Gain 

Compared to P-type solar cells, the N-type solar cells tend to have the efficiency rising obviously. Bifacial solar cells will have a wider application prospect by virtue of the bifacial generating capacity and higher system efficiency and are especially suitable for snowrich areas and such distributed generation systems as roofs, fences and sound barriers. 

Bifacial Power Generation 

The cell back efficiency can reach more than 19% and the back incident rays can be used to improve the generating capacity of the system, with the unit area capacity gain up to 10% ~ 30%. 

For the glass module with bifacial cell technology, the light is caught both on the front and on the back of the module. The increase light input increases the efficiency of the module. Up to 360 Wp total power can be achieved via the active module rear (290 Wp only front / total 320 - 360 Wp). 

The efficiency profit depends on the radiation situation (atmosphere and background).

low / medium reflecting surfaces (e.g. tile roof, grass); Mounting distance to substrate min. 40 cm

good reflective surfaces (e.g. flat roof with gray film , sand); Mounting distance to the ground 60 cm - 1.5 m

very good reflective surfaces (e.g. glacier, snow); Mounting distance to the ground larger than 1.5 m

High Efficiency

front side: 

22 %

rear side: 

19,5 %

Technical Specifications
Strong weak illumination response 

The N-type substrate materials feature longer minority carrier lifetime, so the N-type Bifacial Modules can offer better generating capacity than the conventional P-type modules under low light settings.

Lower Temperature Coefficient   

Under the condition of the same temperature rise, the power attenuation of N-type modules is smaller than that of the P-type modules. 

Low Degradation Coefficient
