For Photovoltaic Measurement
IRVINE, Calif., Oct. 28, 2009 – Newport Corp.’s Oriel Instruments division has announced the Oriel IQE-200, an instrument that permits simultaneous measurement of both the external quantum efficiency (EQE) and the internal quantum efficiency (IQE) of solar cells, detectors and any photon-to-charge converting devices. The integrated and patent-pending measurement system incorporates detector geometry that splits the beam, allowing for concurrent measurements.

Newport_Oriel-IQE-200.jpgWavelength range is from 300 to 1100 nm, working distance is 50 mm, resolution is 5 nm (adjustable), and repeatability is <±0.5. The light source is a 250-W quartz tungsten halogen lamp. Operating temperature is from 0 to 40 °C, input voltage is from 90 to 264 VAC, input current is 15 A, and power consumption is 400 W.

The photovoltaic cell measurement system combines the durable light source, a monochromator, advanced sensor technology, and related electronics and software. The Oriel QE Commander software, preloaded on a PC, is designed to control all the components and accessories, providing simultaneous real-time readout of EQE and IQE in a single measurement with the press of one button. The preconfigured calibrated assembly with four-channel data acquisition for 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 cost-effective Oriel IQE-AC-QTH-SI is the first product in the IQE-200 family of 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, cadmium telluride and more.

The disordered, glassy solid state of a substance, as distinguished from the highly ordered crystalline solid state. Amorphous and crystalline phases of the same substance differ widely in optical and electrical properties.
That branch of science involved in the study and utilization of the motion, emissions and behaviors of currents of electrical energy flowing through gases, vacuums, semiconductors and conductors, not to be confused with electrics, which deals primarily with the conduction of large currents of electricity through metals.
Also known as monochromatic illuminator. An instrument for isolating narrow portions of the spectrum. The spectrum of any light source is formed by a prism or grating, and an exit slit placed in the spectrum selects a narrow band of wavelengths for emission. By moving the spectrum of a source internally past the slit, the color of the emitted light can be varied at will. As most monochromators emit several percentages of unwanted light -- either white or of the wrong wavelength -- along with...
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
