This thesis presents the design and construction of a solar simulator for the characterisation of solar cells. The need for such test equipment has recently increased due to the rapidly growing field of photovoltaics, which includes optoelectronic components and systems for the conversion of light energy into electrical energy.
The presented solar simulator is designed to characterise a perovskite solar cell. It consists of light-emitting diodes that allow modularity, homogeneous illumination of the surface and the achievement of standard test conditions. Such offerings on the market are extremely ex-pensive, rarely available and do not offer the modularity we would like.
In this thesis, we have reviewed existing simulators and their basic concepts of operation. Our starting point was the completed master’s thesis by Žiga Korošak [1].
We selected suitable LEDs with a maximum emitted light density between 400 nm and 800 nm wavelength. We have implemented a power supply that provides an output voltage of 19,2 V and 1,5 A of output current, we have produced LED modules with 6 LEDs, which when combined together provide a modular light source, for the purpose of achieving illu-mination on any surface size. We have designed and implemented software on the MiŠKo3 platform for arbitrary brightness adjustment of the modules, which is able to operate inde-pendently and via a computer. An LED panel, interconnecting several modules and a circuit board allowing communication between MiŠKo3 and the LED modules have also been de-veloped.
