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
≥%0 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
