NPC original laser inspection method

NPC original laser inspection method

Detects cracks in the cells/strings/modules accurately by irradiating laser beam

  • Detects only the cracked areas by distinguishing low power generating area, impurity and cracks
  • Visualizes defective areas clearly through our own software
  • Raises product yield by preventing any misjudgments caused by human errors
  • Innovative technology adopted as SEMI PV60-0115 standard (Test Method for Measurement of Cracks in Photovoltaic (PV) Silicon Wafers in PV Modules by Laser Scanning Method)
  • No need to apply electric current onto cells/strings/modules
  • Raises quality reliability of final products
  • Applicable to cells, strings, and modules
  • Complies with EN60825-01, safety standard of laser light
