This thesis presents the design of a tunable LED solar simulator of six different wavelengths, with an area of 50x50 cm. The optical system was designed as a matrix of 24x24 LEDs divided into unit cells of 6x3 light sources with their specific secondary optics. Theoretical and optical simulations were performed with MATLAB and Ansys SPEOS, to study the LEDs placement on the board and to follow the requirements of the standard IEC 60904‑9:2020 on photovoltaic devices. Finally, the physical realization and optimization of the illuminator have been executed.

Abstract

This thesis presents the design of a tunable LED solar simulator of six different wavelengths, with an area of 50x50 cm. The optical system was designed as a matrix of 24x24 LEDs divided into unit cells of 6x3 light sources with their specific secondary optics. Theoretical and optical simulations were performed with MATLAB and Ansys SPEOS, to study the LEDs placement on the board and to follow the requirements of the standard IEC 60904‑9:2020 on photovoltaic devices. Finally, the physical realization and optimization of the illuminator have been executed.
