Measures EQE, IQE, spectral response and IPCE of solar cells made from a wide range of materials.

The SCS600 series measures the quantum efficiency and spectral response of solar cells of various materials using the substitution method against a calibrated standard detector, for university and institute labs as well as industrial R&D and production QC. It works with Keithley 2612B and 2636B source meters for accurate data acquisition and bias testing, and a large sample chamber with double doors simplifies sample loading. Xenon, tungsten and dual-source versions cover 300–1100 nm (1700 nm optional) up to 300–2500 nm.

Key Features

  • EQE, IQE, spectral response and IPCE measurement with integrated Jsc calculation
  • Xenon and tungsten light sources with stability better than 99% for repeatable substitution-method results
  • All-reflective optical path avoids chromatic aberration, so the spot size stays the same at every wavelength
  • 150 W xenon lamp delivering more than 6 mW/cm² at 500 nm
  • Bias light and bias voltage tests, light beam induced current (LBIC) measurement, AC and DC data acquisition
  • Monitoring CCD camera for spot observation and precise sample positioning
  • Measures samples inside glove boxes and vacuum chambers; IPCE-PVK glove-box accessory available

Typical Applications

  • Quantum efficiency of solar cells of various materials
  • Multi-cell samples measured with LED bias light
  • Dye-sensitized solar cells
  • Air-sensitive samples in glove boxes
  • University and institute photovoltaic research
  • Industrial R&D and production quality control
