Abstract

V tem diplomskem delu sta predstavljeni zasnova in izdelava sončnega simulatorja za ka-rakterizacijo sončnih celic. Potreba po tovrstni testni opremi se v zadnjem času povečuje zaradi hitrorastočega področja fotovoltaike, ki obsega optoelektronske komponente in sisteme za pretvorbo svetlobne energije v električno. Predstavljeni sončni simulator je namenjen karakterizaciji in staranju perovskitnih sončnih celic. Sestavljajo ga svetleče diode, ki omogočajo modularnost, homogeno osvetlitev povr-šine in doseganje standardnih testnih pogojev. Tovrstne ponudbe na trgu so izredno drage, redko dostopne in ne omogočajo takšne modularnosti, kot bi si jo mi želeli. V tem diplomskem delu smo pregledali že obstoječe simulatorje in njihove osnovne koncep-te delovanja. Izhajali smo iz magistrske naloge Žige Korošaka [1]. Izbrali smo ustrezne svetleče diode z največ izsevane svetlobe v spektralnem območju med 400 nm in 800 nm valovne dolžine. Realizirali smo napajanje svetlečih diod, ki omogoča izhodno napetost 19,2 V in 1,5 A izhodnega toka, in za namen doseganja osvetlitve na po-ljubni površini izdelali LED module s šestimi svetlečimi diodami, ki združene omogočajo modularno svetilo. Programsko opremo za poljubno nastavitev svetlosti modulov, ki je zmožna delovati samostojno in preko računalnika, smo zasnovali in realizirali na platformi MiŠKo3. Razvita sta bila tudi LED panel, medsebojna povezava več modulov in vezje, ki omogoča komunikacijo med platformo MiŠKo3 in LED moduli.

Secondary title: Universal LED light source for solar cell characterization
Secondary abstract: 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.
