Evaluation of an LED Simulator for Single- and Multi-Junction PV Cell Performance Testing

Conference ·
; ; ; ; ; ;

We present the evaluation of a solar simulator comprising a Light Emitting Diode (LED) array as its light source. While multiple applications can be envisioned for such a light source, here we focus on its use for performance testing of solar cells at Standard Test Conditions. With this in mind, we present characterization of the spatial uniformity of the irradiance and its temporal stability as well as the spectral range and spectral class. For a multisource simulator, the spectral uniformity across the test plane should also be evaluated and we discuss a method for performing this evaluation that is well suited to a solar cell performance testing application. One major advantage of this simulator is the ability to easily adjust the spectral output as needed in multijunction PV cell measurements and we also discuss this application here.
