Rapid advances in high intensity light emitting diodes (LEDs) have provided sufficient tools to design LED solar simulators to accurately mimic the sun. LEDs offer numerous advantages over lamp-based technology currently used. However, these advantages have not been harnessed because of limitations in creating a solar simulator with the highest rating (AAA) for spectral match, temporal stability, and light uniformity. Oriel's VeraSol is one of the first LED, triple A solar simulators. The VeraSol-LED was compared to the equally rated Oriel Sol3A-xenon lamp solar simulator by measuring the current-voltage (I-V) response and spectral response (SR) for a variety of solar cells. Both simulators effectively mimic the sun; however, the results demonstrate the LED-based simulator produced a more stable, flexible, and accurate match to AM1.5G than the xenon lamp-based simulator with similar marks in the quality of PV cell response.
