Supplementary material to manuscript "Unfolding electrolyzer characteristics to reveal solar-to-chemical efficiency potential: rapid analysis method bridging electrochemistry and photovoltaics " accepted for publication to ChemSusChem journal in November 2024Authors: Oleksandr Astakhov, Therese Cibaka, Lars Wieprecht, Uwe Rau, Tsvetelina Merdzhanova    IMD-3 Photovoltaics Forschungszentrum Jülich GmbH, Jülich, GermanyVersion 5 14.11.2024Contact: Oleksandr Astakhov email: [e-mail] of maximum STC (solar to chemical efficiency, same as STF - solar to fuel efficiency) in photovoltaic-driven electrolyzers (PV-EC) The analysis addresses any type of PV-EC systems with direct and indirect couplingCoupling efficiency ηC is treated as a constant explicitly. Set  ηC to be 100% to evaluate the limit of STC the electrolyzer can achieveThe analysis is performed towards individual products. If EC produces several products each of them must be analysed in a separate tableSTC dependencies for three major parameters PV-efficiency, Irradiance G and PV-to-EC area ratio AR are calculatedExample dataset is for EC cell for CO2 reduction with data presented for CO as a product
