Contact resistance scan system

This solar cell characterisation instrument allows the visualization of various energy loss locations across the cell and helps in optimisation of various process parameters.

Make and Model

Mechatronics Manufac turing, BV/SCRA 10: 9001

Available mode for use

  • Core (contact resistance) scan: Full surface measurement of contact resistance of front side metallisation

  • Shunt scan: Locates shunts on solar cells and finds out about their nature

  • Open circuit voltage (Voc) scan: Finds the locations of increased recombination

  • LBIC (Light beam induced current) scan: Finds the regions on a solar cell with reduced short-circuit current density.
