The QE-PV-SI is a preconfigured, yet flexible, solution for measuring Quantum Efficiency (QE), also known as Incident Photon to Charge Carrier Efficiency (IPCE). Oriel selects, assembles and tests all the necessary items as a complete system prior to shipment. The user’s manual provides instructions for connecting the cables and configuring the software. Once configured, measuring a solar cell, detector or other photon-to-charge converting device is simple and convenient. Instruments are controlled and scan parameters are set up through simple, intuitive dialog boxes. The complete system includes an ozone-free Xenon light source, optical chopper, lock-in amplifier, monochromator, order sorting filters, reference detector, related electronics and Oriel’s TracQ™ Basic software.
