  • Measurement of a solar cell
  • The right busbar is not connected to the cross connector

  • Measurement of a solar cell with microcrack
  • The crack is clearly visible
  • No soldering points are visible below the crack
  • The crack has cut through the busbar

  • Measurement of a cell
  • The solder points become visible in the By-component of the magnetic field
  • Some solder joints are missing
  • It can also be determined whether the solder pads are centered on the pad.

  • Measurement of three cylindrical Li-Ion batteries during a charging process
  • The right battery shows an abnormality
  • The changed magnetic field indicates a locally changed current flow
  • MFI allows the detection of defects in accumulators

  • Measurement of a pouch cell during the charging process
  • MFI makes it possible for the first time to visualise the flow of electricity
