About This Webinar

In today’s energy-challenged world, clean energy topics are increasingly important, particularly with solar cell designs reaching new efficiency breakthroughs. This webinar series shares the fundamental measurements for a quantum efficiency system and how they apply to the research and design of a solar cell.

Representatives from MKS Newport present an in-depth discussion of internal quantum efficiency (IQE), external quantum efficiency (EQE), and incident photon to charge carrier efficiency (IPCE). They also share a brief overview of clean energy demand, including the photovoltaics forecast and the effect on solar cell design. Specific requirements that are needed to take these measurements are discussed as well as the key challenges researchers run into during experimentation. Finally, they touch on a typical testing process in multiple equipment configurations. Join MKS Newport experts to learn and dig into the world of solar cell design measurements and how to set up a lab for success.

Who should attend:
R&D scientists, engineers, manufacturers, and researchers working with quantum efficiency measurements. Those who use test and measurement in solar and energy research. Anyone working with detectors, electronics, LEDs, or spectroscopy in industries such as environmental research, biophotonics, and semiconductors.
