The new QE/IPCE measurement kit allows researchers to measure Quantum efficiency (QE) and Incident Photon to
Charge Carrier Efficiency (IPCE) measurement for solar cells, detectors, or any other photon-to-charge converting device. We
selected the most suitable components for your measurements needs. trusttech is an industry leader in light sources and spectroscopy products.

What are QE and IPCE?
Quantum efficiency (QE) and Incident Photon to Charge Carrier Efficiency (IPCE) indicates the ratio of the number of photons
incident on a solar cell to the number of generated charge carriers. Quantum efficiency is a measure of external efficiency, while IPCE considers the internal efficiency; that is, the photons reflected back from the surface of the cell are not considered.
The QE/IPCE measurements are critical especially during the materials research and cell design stage—because it is of great importance for a device to have an optimal spectral response at the point at which the spectral component of the sunlight is abundant. The system is built by an industry leader in light sources and spectroscopy, so you can rely on our expertise to ensure accuracy of the measurement.

How to Measure QE and IPCE?
The key to accurately measure the QE/IPCE of a solar cell is to quantify the intensity of monochromatic light incident to the
device under test and how much current is generated. We provide the most important components, which are the most
common building blocks of a QE/IPCE system that will allow you to quickly set up the experiment.
