Product Overview
The QUANTX-300 leverages Newport’s expertise in optical design, spectroscopy, PV
instrumentation, and electronics. These proficiencies have been focused into a complete,
sophisticated measurement system for Quantum Efficiency measurement (EQE and IQE).
The QUANTX-300 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 QUANTX-300 is assembled, preconfigured, 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 QUANTX-300 incorporates a patented detector geometry using a beam splitter, allowing for
simultaneous measurement of EQE and the reflective losses to quantify IQE and a patent pending
circuit that protects your cell when being connected and disconnected from building up charges that
can potentially damage your PV cell. 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.
The QUANTX-300 employs a patent-pending detector design which allows seamless measurement
from 325 to 1800nm.
A variety of accessory models are available to provide positive sample positioning, temperature
control, and electrical probing capabilities.
