Oriel Instruments' Quantum Efficiency Systems empower researchers to measure Internal Quantum Efficiency (IQE) and External Quantum Efficiency (EQE), also known as Incident Photon to Charge Carrier Efficiency (IPCE), for any photovoltaic device. Employing industry leading, durable components for optical performance, these systems are preconfigured, assembled, and calibrated at the factory. The products are a turn-key solution which includes all necessary components with integrated light source, monochromator, detectors, electronics, software, and even the computer. A variety of accessory modules are available to provide positive sample positioning, temperature control, and electrical probing capabilties.

 

·         Complete, turn-key PV efficiency measurement solution

·         Robust, compact design to minimize lab space

·         Simultaneous IQE, EQE, and spectral response measurements

·         Integrated beam chopper with virtual digital lock-in amplifier

·         Achromatic optics: maintains spot size throughout the entire spectral range

·         User-friendly, icon based software interface for simple calibration and IQE measurements

 

 

 

 

Oriel Quantum Efficiency System Set Up Demonstration

Getting any quantum efficiency system up and running is a straightforward process, as demonstrated in this video.

 

 

Sophisticated Technology

These products leverage Newport's expertise in optical design, spectroscopy, precision motion control, and electronics technologies. These proficiencies have been focused into a complete, sophisticated measurement system for Quantum Efficiency (EQE and IQE). Both systems incorporate a patented detector geometry using a beam splitter, allowing for simultaneous measurement of EQE and the reflective losses to quantify IQE. Unique to these models are a sample stage with an integrated vacuum chuck and thermistor. They also include 4-wire sense measurement option which broadens the capabilities to include a large range of sample sizes and efficiencies.

 

 

Intuitive Software

The acquisition and controls software for these QE solutions is pre-installed on a laptop computer which is included with the measurement system. The software uses an intuitive, icon based graphical interface to provide instrument controls, configuration, and data acquisition. The software seamlessly controls all of the system components. EQE and IQE curves are calculated and plotted as a function of wavelength in a single scan without the need to reposition the detectors or sample, optimizing measurement accuracy and repeatability. There is also an integrated, software-controlled sample voltage bias feature, which allows users to adjust from -10 to +10V.
