Abstract

V diplomskem delu smo preučevali tehnologijo perovskitnih sončnih celic pri notranji razsvetljavi. Tehnologija velja za eno izmed najobetavnejših na področju zelenega prehoda. Z nizko ceno izdelave in visoko učinkovitostjo pretvorbe moči (PCE) pri obsevanju s soncem ali umetnimi svetili bi lahko nadomestila silicijeve sončne celice. Izdelali smo perovskitne sončne celice ter jih testirali pri različnih spektrih in intenzitetah notranje LED sijalke. Dosegli smo PCE v višini 18% pod klasičnim umetnim soncem in 31 % pri notranji osvetlitvi. Iz meritev PCE pri notranji osvetlitvi, pri katerih smo dobili visoko PCE, lahko sklepamo, da perovskitne sončne celice zelo dobro absorbirajo svetlobo v vidnem delu spektra, zaradi česar so idealne za notranjo uporabo. Rezultati meritev bele LED sijalke za notranjo osvetlitev so pokazali, da je svetloba najbolj homogena okoli centralne točke, kjer smo tudi izvedli ostale meritve. Ugotovili smo, da intenziteta svetlobe vpliva na sam spekter, in sicer se največja razlika opazi med najnižjo in najvišjo intenziteto. Iz meritev je razvidno, da so celice bolj prilagojene na spekter s toplejšo belo barvo LED svetilke, saj je v tem primeru PCE bila višja.

Secondary title: Characterisation of perovskite solar cells under indoor lighting
Secondary abstract: In this thesis, we studied the technology of perovskite solar cells under indoor light illumination. This technology is considered one of the most promising in the field of green transition. With low manufacturing cost and high power conversion efficiency (PCE) when exposed to sunlight or artificial lights, perovskite solar cells could potentially replace silicon solar cells. We manufactured perovskite solar cells and tested them under different spectra and intensities of indoor LED light. We achieved a PCE of 18 % under 1-sun condition and 31 % under indoor illumination. Based on the PCE measurements under indoor illumination, where we obtained high PCE values, we can conclude that perovskite solar cells effectively absorb light in the visible spectrum, making them ideal for indoor use. The results of measurements with a white LED for indoor lighting showed that the light is most homogeneous around the central point, where we conducted other measurements as well. We found that the intensity of light affects the spectrum, with the greatest difference observed between the lowest and highest intensities. It is evident from the measurements that the cells are better suited to the spectrum of a warmer white LED, as in this case, the PCE was higher.
