PVE300 System - Accurate Determination of Solar Cell EQE

Bentham’s PVE300 system is a crucial tool 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 full compatibility with a range of photovoltaic devices, architectures and materials, including chalcogenides, quantum well, quantum dots, perovskites, multi-junction (2-, 3-, 4-junction and more), tandem, CIS, CIGS, Ge, CdTe, mc:Si, µ:Si, a:Si, c:Si, dye-sensitized, and organic/polymer.

Core Benefits

  • Enhanced quality optical components ensure stable system performance
