Newport’s Oriel IQE 200 measurement system allows researchers to measure External Quantum efficiency (EQE) also known as Incident Photon to Charge Carrier Efficiency (IPCE) as well as Internal Quantum Efficiency (IQE) for solar cells, detectors, or any other photon-to-charge converting device.
The system utilizes industry standard, durable Oriel components for the light management engine. Each model of the IQE-200 system provides a “turnkey” solution by providing the light source, monochromator, detectors, related electronics, software and PC in a preconfigured, assembled and calibrated format. A variety of accessory modules are available to provide positive sample positioning, temperature control, electrical probing capabilities and light bias. The IQE-200 incorporates a novel detector geometry which splits the beam allowing for simultaneous measurement of EQE and the reflective losses to quantify IQE. In addition, an accessory detector can be mounted which allows for measurement of Transmission through the cell for those samples on a transparent substrate. The unique design of the AC system meets the requirements outlined in ASTM Method E 1021-06.
The IQE-200 accessories customize the system to perform QE measurements incorporating temperature control, light biasing, and even motorized mapping capabilities all controlled by our new QE Commander ™ software system. Adding a source meter also allows for point measurements of the IV response of the cell. In conjunction with motorized mapping, it allows the user to “map” the IV performance of the cell under test in a user definable pattern.
All Oriel components are from Newport Corporation, an industry leader in light sources, spectroscopy products, precision motion control, and continuous wave solar simulators.
