Abstract

Solar simulator is a device used to replicate the sunlight in term of its spectrum. Several types of lamps including Xenon arc lamps, LEDs, metal halide and halogen lamps were commonly used in the development of solar simulators. In order to determine the performance of a solar simulator, three characteristics had been set by the IEC 60904-9 which include the spectral match, spatial non-uniformity and temporal stability. With the presence of ASEL’s solar simulator in UTeM, this paper presents a study conducted to define two important performance parameters of the solar simulator which are spectral match and spatial non-uniformity. Mathematical modelling method was applied to find the spectral irradiance spectrum of the light source; it was then be compared with the AM1.5G spectrum to determine the spectral match. Meanwhile, for spatial non uniformity experiment, irradiance mapping method was used where the reading of irradiance intensity at each coordinate across the map was measured. This study has shown that ASEL’s solar simulator only managed to achieve the minimum requirement of spectral match at two wavelength bands which are 400-500nm and 500-600nm; whereas for 600-700nm range, the spectral match measured was beyond the range set. On the other hand, this study also reveals that the solar simulator tested was capable to produce percentage of spatial non-uniformity that complied to IEC 60904-9 standard. With average irradiance intensity of 981.98 W/
