Newport Corporation's Oriel Instruments division has introduced the IQE-200 integrated measuring instrument.
The instrument 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 Oriel IQE-200 system is a patent-pending design incorporating novel detector geometry that splits the beam, allowing for concurrent measurements.
The photovoltaic cell measurement system combines a 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 all the components and accessories, providing a simultaneous, real-time readout of EQE and IQE in a single measurement with the press of a button.
The preconfigured calibrated assembly with four-channel data acquisition for very rapid measurement is a turnkey solution.
The AC measurements are performed in accordance with ASTM 1021-06 guidelines, offering reliable operation and easy installation with minimal setup time.
The Oriel IQE-AC-QTH-SI is the first product in the IQE-200 range 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) and cadmium telluride (CdTe).
