OVERVIEW |SOLAR MODULES |THE SMART DIFFERENCE | TECHNOLOGY | REFERENCES
PERC CELL TECHNOLOGY
PASSIVATED EMITTER, REAR CONTACT
 High Transmittance
≥%0
  High Impact Resistance
PERC architecture enables to improve light capture near the rear surface and to optimize electrons capture which significantly improves the cell efficiency.
 5BB Front Electrode Design
Better Current Collection Ability
 Outstanding Performance at Low Irradiance

Half-Cut Cell Technology

 High Efficiency
+5 ~ 10 W
Reduced Resistive losses
When the cell is cut in half (158.75 x 78.375 mm), the amount of electrical current is halved which leads to lower resistive losses
  Lower Operation Temperature & Lower Hot-Spot Impact
Higher Reliability Of The Module
 Higher Shade Tolerance
Higher Performance In Partial Shadow Conditions
BIFACIAL PERC CELL TECHNOLOGY
PASSIVATED EMITTER, REAR CONTACT
 Improved Panel Performance
≥%only front

Bifacial PERC has a significant advantage which has the potential to absorb additional sunlight by rear surface.
  5BB Front/Rear Electrode Design
More Transparent Rear Side At rear side, Al back surface field is replaced by Al grid.
 Bifaciality Factor %75-%80
BIFACIAL POWER PRODUCTION
Bifacial Panel Performance depends on the amount of light that reaches the rear side:

Albedo
Installation Height of Module
Ground Cover Ratio-Row Spacing
Diffusion Horizontal Irradiance

 Albedo
The albedo describes the reflectivity of a surface.
 Installation Height of Module
Increasing module height
(above 1m )
→ Higher rear side energy yield
→ More irradiance uniformity on rear side of module.
 Row Spacing
Lowering spacing
→ Higher irradiance on rear side of module
→ Higher area for reflected light from the ground
 DHI
Bifacial gain from rear side mostly depends on diffuse light
→ From the ground reflected
→ From the sky diffused
BIFACIAL POWER GAIN
