Abstract:
Solar energy becomes one of the most promising renewable energy sources available in the modern age. Due to the enormous expansion of the production of solar cells and solar radiation conversion modules, it is very important to provide an appropriate environment (equipment and software) for testing their efficiency under standard conditions. The solar simulator provides a controlled closed facility for testing solar cells and photovoltaic modules under laboratory conditions, emitting radiation that approximates natural sunlight. Light sources represent the most important component of solar simulators used in the research of photovoltaic devices. Today, LEDs have become popular as a solar simulator lighting source due to their advantages (compactness, low energy consumption, low cost, long lifetime, etc.) over conventional light sources. This work focuses on measuring, analyzing and matching the output spectrum response of the LED solar simulator with the reference spectral distribution of sunlight in the visible spectral range at AM1.5 with the help of a spectrometer, according to official world standards. Experimental measurements were performed in the Solar Energy Laboratory of the Academy of Sciences and Arts of the Republic of Srpska in Banja Luka.
