Abstract

LED-based solar simulators are gaining popularity in the PV characterization field. There are several reasons for this trend, but the primary interest is often the potential of tuning the light source spectrum to a closer match to the AM 1.5G reference spectrum than traditional Xenon or metal-halide light sources provide. In this work we will use an EcoSun10L LED module tester from Ecoprogetti to perform short circuit current (ISC) measurements under various class A, B and C spectra. We will apply a spectral mismatch correction to the measured ISC under each test spectrum per IEC 60904-7. In all scenarios, a small area mono-Si cell is used the reference cell and a similar mono-Si cell is used as the PV device under test (DUT). Finally, we quantify the variation of the DUT’s measured and spectrally corrected Isc under the class A, B and C test spectra.
