Global energy needs are projected by the EIA to outpace efficiency gains through 2050, intensifying the demand for innovative, accurate, and sustainable testing solutions. This webinar by Innovations in Optics, Inc. (IOI) explores how next-generation LED solar simulators are accelerating the development of high-efficiency solar technologies to meet this global challenge.
Attendees will learn how LED-based systems provide a cost-effective, energy-efficient, and environmentally responsible alternative to legacy Xenon-arc systems, often consuming less than 75 W per 1 Sun compared to over 300 W. Topics include an overview of solar simulators, IEC Class definitions, Spectral Deviation (SPD) and Spectral Coverage (SPC), and key design considerations for LED-based systems. The session will address illumination field uniformity, bifacial configurations, and temperature stability, as well as methods for controlling wavelengths to study reflection and absorption phenomena critical in advanced solar-cell characterization.
The webinar will also discuss how tunable, multi-channel LED simulators support research in tandem and multi-junction solar cells, such as combining standard solar cell materials with perovskites to extend spectral sensitivity from 300nm to 1250nm (or longer) and enhance total conversion efficiency. In addition, we will review the importance of understanding the effect of lower UV wavelengths on system performance and long-term stability.
Engineers, researchers, and manufacturers involved in PV development, quality assurance, materials or solar-device testing will gain insight into achieving Class A+ accuracy and long-term stability while reducing power consumption and ownership costs. Ultimately, participants will see how LED solar simulators are helping to pave a responsible path toward clean, renewable energy for all.
