Description: QE-R quantum efficiency system is a PV cell tester which can provide cell’s QE (quantum efficiency), PV-EQE (external quantum efficiency), IPCE (incident photon-to-electron conversion efficiency), SR (spectral response), IQE (internal quantum efficiency), Reflectance. Two independent lock-in amplifiers, which monitor the optical power and measure the device signal simultaneously.


  • Absolute light intensity calibration.
  • SR, EQE measuring.
  • Auto in-situ Jsc(EQE) calculation.
  • Auto Jsc(EQE) calculation at each wavelength.
  • IQE calculation. 
  • Bandgap analysis.
  • Data collecting and analyzing.
  • Mismatch factor (MMF) calculation.
  • Signal monitoring function.
