Measurement Solution, Quantum Efficiency

The new IQE 200B leverages 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). The IQE 200B empowers researchers to measure Internal Quantum Efficiency (IQE) and quantify 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, the IQE 200B is preconfigured, assembled, and calibrated at the factory. The product is a turn-key solution which includes all necessary components with integrated light source, monochromator, detectors, electronics, software, and even the computer.

The IQE 200B incorporates a patented detector geometry using a beam splitter,
allowing for simultaneous measurement of EQE and the reflective losses to quantify
IQE. Unique to this model is an integrated, software-controlled sample voltage
bias, adjustable from -10 to +10V. This model also includes a 4-wire sense which
broadens the capabilities to include a large range of sample sizes and efficiencies.
A variety of accessory models are available to provide positive sample positioning,
temperature control, and electrical probing capabilities.
