Merjenje ambientalne svetlobe za karakterizacijo perovskitnih sončnih celic

Trpcheska, Angela (author), Jankovec, Marko (mentor)

Moč vpadne svetlobe je ključna informacija pri karakterizaciji sončnih celic, kjer predstavlja mero vložene energije, katere del se v sončni celici pretvori v električno. Na tej podlagi določimo učinkovitost pretvorbe, ki je eden najpomembnejših parametrov sončnih celic. Meritev moči vpadne svetlobe se običajno izvaja z referenčno sončno celico, ki je umerjena na referenčni sončni spekter AM1.5. Pri uporabi sončnih celic v notranjih prostorih pa so svetlobne razmere povsem drugačne, saj se sončna svetloba meša s svetlobo umetnih svetil. Za namen merjenja ambietalne svetlobe v notranjih prostorih sem se lotila izdelave merilnega sistema, ki omogoča zanesljivo in natančno merjenje ambientalne svetlobe. Pri razvoju sistema sem izbrala komponente, kot so senzorji za merjenje fotometrične osvetlitve v luksih in fotodiode za merjenje radiometrične moči vpadne svetlobe v W/m². Sistem sem načrtala s programsko opremo Altium Designer. Krmiljenje merilne naprave sem izvedla z razvojno mikrokrmilniško ploščico MiŠKo3 v programskem okolju STM32CubeIDE. Vsi merilni rezultati se prikazujejo na zaslonu. Izdelan merilni sistem omogoča natančno meritev ambietalne svetlobe za karakerizacijo perovskitnih sončnih celic v notranjih pogojih delovanja.

• Title: Ambient light measurement for characterisation of perovskite solar cells

Abstract

The measurement of irradiance is a crucial aspect in the characterization of solar cells, as it quantifies the amount of energy input, a portion of which is converted into electricity within the solar cell. On this basis, we determine the conversion efficiency, which is one of the most significant parameters of solar cells. Measurements of irradiance are typically performed with a reference solar cell calibrated to the AM1.5 reference solar spectrum. However, when using solar cells indoors, the lighting conditions are entirely different, as sunlight mixes with artificial light sources. For the purpose of measuring ambient light indoors, I developed a measurement system that enables reliable and accurate measurement of ambient light. During the system design process, I chose components such as sensors for measuring the photometric illuminance in lux and photodiodes for measuring the radiometric irradiance in W/m². I designed the system with the Altium Designer software. The control of the measurement device is carried out through the MiŠKo 3 development microcontroller board using the STM32CubeIDE programming environment. All measurement results are displayed on the screen. The developed measurement system enables accurate measurement of ambient light for the characterization of perovskite solar cells under indoor operating conditions.
