Accurate Determination of Solar Cell EQE – PVE300

Bentham’s PVE300 system is an important instrument in photovoltaic research and production line quality procedures. It is used for the accurate definition of solar cell EQE (IPCE)/spectral response and IQE.

The PVE300 offers total compatibility with a variety of photovoltaic devices, architectures and materials, including perovskites, quantum well, quantum dots, chalcogenides, multi-junction (2-, 3-, 4-junction and more), tandem, Ge, CIS, CIGS, CdTe, µ:Si, a:Si, mc:Si, c:Si, dye-sensitized, and organic/polymer.

Core Benefits

  • Enables PV research
  • Complete EQE and IQE characterization on material and device level
  • Improved quality optical components ensure stable system performance
  • Measure all kinds of device architectures and materials including multiple junction


  • Broad range of operation (300 to 2500 nm). If a range beyond this is required, customers can enquire
  • Improved tunable light source based on single monochromator and xenon-quartz tungsten halogen dual source
