Newport Corporation's Oriel Instruments division has introduced the Oriel IQE-200, a measuring instrument for assessing the performance of photovoltaic devices. The instrument permits simultaneous measurements of both the external quantum efficiency (EQE) and the internal quantum efficiency (IQE) of solar cells, detectors, or any photon-to-charge converting devices. The detector features a novel geometry that splits the beam, allowing for concurrent measurements.
The photovoltaic cell measurement system combines a rugged 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 all the components and accessories, providing a simultaneous, real-time readout of EQE and IQE in a single measurement.
The IQE-AC-QTH-SI is the first product in the IQE-200 family of Newport-Oriel systems for measuring total solar cell quantum efficiencies. It is suitable for the measurement of silicon-based cells, both amorphous and mono/poly-crystalline, thin film cells, copper indium gallium diselenide (CIGS), cadmium telluride (CdTe), and more.
