    • Current amplifier for low signal measurements
  • Easy to use control software with data export
  • Upgrade for photoluminescence and electroluminescence (PL/EL) available

Applications and functions

  • Fast and reliable photocurrent mapping with highest resolution
  • Defect detection and visualization – shunts, coating defects, localize inactive regions
  • Study degradation effects
  • Quality control tool
  • A laser beam scans the sample and the excited photocurrent is measured
  • Different (multiple) laser wavelengths available
  • Up to  300×300 mm² scanning area
  • Mapping of all kinds of solar technologies:   Perovskite, Organic, Silicon, CIGS, CdTe, …
