This data set was used for the modelling in the article M. Kölbach, O. Höhn, K. Rehfeld, M. Finkbeiner, J. Barry, and M. M. May, “The annual-hydrogen-yield-climatic-response ratio: evaluating the real-life performance of integrated solar water splitting devices”, Sustainable Energy Fuels, 2022, 6, 4062-4074, https://doi.org/10.1039/D2SE00561A. It contains the External Quantum Efficiency (EQE) data of a wafer-bonded AlGaAs//Si dual-junction solar cell for several top absorber compositions, angle of incidences, and temperatures modelled using the OPTOS formalism (see https://doi.org/10.1364/OE.24.0A1083 , https://doi.org/10.1364/OE.23.0A1720 , and https://doi.org/10.1109/JPHOTOV.2021.3064562). Moreover, the data set includes hourly resolved direct and diffuse solar spectra for a location near the Neumayer station in Antarctica (-70.67°/-8.28°) that were modelled using the libRadtran software package for the year 2021 (see https://doi.org/10.1140/epjconf/e2009-00912-1 and https://doi.org/10.5194/acp-5-1855-2005). The modelling of the spectra was performed employing the predefined “subarctic summer” and “subarctic winter” atmosphere datasets assuming a tilt angle of 70° and 1-axis tracking. For the sake of simplicity, no cloud cover was assumed over the course of the whole year. Finally, the input files required for modelling the climatic response of solar water splitting devices for the selected location in Antarctica using the “climatic_response_function” of YaSoFo (see https://doi.org/10.5281/zenodo.5257492 for an extended example) are included in the data set.
