TOPCon Type N Technology
Type N Bifacial Solar Cells
- High conversion efficiency with high reliability
- Uniform cell performance with stable process control
- Both sides can generate electricity
- Low mismatch of cell performance during encapsulation
- Excellent power generation performance under low irradiation conditions
- Low hot spot effect
Type N Bifacial Solar Modules
- Double-sided modules combine leading NTOPCon, 9BB and half cell technology.
- The N-type material has zero LID / LeTID risks and makes the modules more reliable, more bi-ease, higher efficiency, lower temperature coefficient and longer life.
- Number of cells: 120pcs (12 * 10)
- Maximum efficiency （%）: 21.03%
- Operating temperature （℃）: -40 ℃ ~ + 85 ℃
- Maximum System Voltage (V): 1500V (IEC)
- Temperature coefficient of Pmax: -0.32% / ℃
- Nominal Operating Cell Temperature (NOCT): 42 ± 2 ℃
No Light Induced Degradation
TOPCon is a N-type silicon substrate battery. Phosphorus doped N-type crystalline silicon contains extremely low boron content, which weakens the boron-oxygen influence.
