Photovoltaic EQE (IPCE) and IQE Solution - PVE300

The PVE300 system from Bentham is an important instrument in photovoltaic research and production line quality procedures, used for the accurate determination of solar cell EQE (IPCE)/spectral response and IQE.

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