Online monitoring of the spectral characteristic of a flashed solar simulator for performance assessment of multijunction solar cells

This work presents the implementation of high-speed spectral measurements for online monitoring of the spectral characteristics of a flasher solar simulator necessary to apply the mismatch spectral correction between the standard ASTM G173-03 AM1.5 1000 W/m2 spectrum and the solar simulator one. The characterization setup to evaluate linearity with lamp voltage, in time and wavelength, for the proper characterization of photovoltaic of multijunction solar cells is reported.
