Abstract

We present a thorough evaluation of a first-of-its-kind quad-source AM 0 solar simulator developed by TS-Space Systems and installed at the AFRL Space Vehicles Directorate in Kirtland AFB, NM. With an underlying need to evaluate more complex and advanced space photovoltaics, the TS-Space Unisim 100 was chosen as replacement to the Spectrolab X-25. Several parameters of the Unisim were characterized including spectral irradiance, lamp stability (long-term and short-term), spatial uniformity, and repeatability. In addition, the impact of test plane translation due to variable cell holders was studied. The potential impact of AC input voltage to lamp ballast was also investigated. Further, comparisons are made to the X-25. Finally, operational considerations for the use of a multi-source simulator are discussed.
