Solar cell TOPCon Type N Technology

Solar cell 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.
