The IQE-200 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.

Wavelength 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.
