Calibration of reference solar cells using the solar simulator method. Reference cells with GaAs that have similar spectral sensitivity characteristics and high stability.
GaAs-type (III-V compound semiconductor) cells have spectral sensitivity characteristics that are much more similar to perovskite-type cells compared to conventional Si-type cells, and they also excel in stability. GaAs-type cells show significantly better spectral mismatch when compared to measurements using the combination of the commonly used "Si-type cell" and the colored glass filter KG-5 as a reference for perovskite-type cells. ReRa Solutions in the Netherlands is one of the few companies manufacturing high-quality GaAs-type reference solar cells, and we have established a system to provide stable supply and technical support within Japan, leveraging our know-how in the manufacturing and sales of our own reference solar cells. Our reference solar cells also comply with the standards of the WPVS (World Photovoltaic Scale) and the requirements of IEC 904-2. Additionally, cell calibration is conducted at the Radboud University Nijmegen PV Measurement Facility and is traceable to the NREL in the United States.
