This paper discusses the development and fabrication of a scalable large-area LED-based solar simulator that consists of multiple tapered light guides. Power delivery in the form of a synthesized AM 1.5 spectrum over an area of 25 cm × 50 cm with better than 10% spatial nonuniformity is demonstrated, and the spectral output, the spatial uniformity, and the temporal stability of the simulator in both the constant current mode and the pulsed-mode LED operation is evaluated and discussed.
