Newport Corporation (Irvine, CA) has introduced the Oriel IQE-200™, an instrument that permits simultaneous measurements of the external quantum efficiency (EQE) and the internal quantum efficiency (IQE) of solar cells, detectors, or any photon-to-charge converting devices. The photovoltaic cell measurement system combines a rugged and durable Oriel light source, a monochromator, advanced sensor technology, and related electronics and software. The Oriel QE Commander™ software, pre-loaded on a PC, is designed to control the components and accessories to provide a real-time readout of EQE and IQE in a single measurement with the press of a button. The preconfigured, calibrated assembly with 4-channel data acquisition is a turnkey solution, and the AC measurements are performed in accordance with ASTM 1021-06 guidelines.
