(orcid)0000-0001-6040-1920 Enhanced power-point tracking for high-hysteresis perovskite solar cells with a galvanostatic approach 2024 Access copy available to the general public Unrestricted Harnessing the untapped potential of solar energy sources is crucial for achieving a sustainable future, and accurate maximum-power-point tracking of solar cells is vital to maximizing their power generation. This article introduces a power-tracking algorithm and cost-effective hardware for long-term operational stability measurements in perovskite solar cells. Existing algorithms for photovoltaic technology lead to suboptimal performance when applied to the most stable perovskite devices (for example, triple-mesoscopic hole-transport-material-free metal halide perovskite solar cells). To address this challenge, we developed a low-cost hardware solution for research purposes that enables concurrent long-term stability measurements in parallel with a galvanostatic-type power-tracking algorithm, ensuring superior operational performance for high-hysteresis perovskite solar cells. The suggested enhancements bear significant implications for the extensive integration of perovskite solar-cell technologies, particularly those dependent on power-optimizer devices. info:eu-repo/grantAgreement/ES/AEI/PID2020-116011RB-C22 info:eu-repo/grantAgreement/ES/DGA/E31-20R info:eu-repo/grantAgreement/ES/DGA/T27-23R info:eu-repo/grantAgreement/ES/UZ-DGA/T57-23R info:eu-repo/grantAgreement/ES/MICINN AEI/EIN2020-112315 info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-107893RB-I00/AEI-10.13039-501100011033 info:eu-repo/grantAgreement/ES/MCIU/IJC-2020-044684-I info:eu-repo/grantAgreement/ES/MICINN/PID2019-108247RA-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2022-140516OB-I00 info:eu-repo/grantAgreement/ES/MICINN/RYC-2018-025222-I info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 7.3 2024 MATERIALS SCIENCE, MULTIDISCIPLINARY 98 / 461 = 0.213 2024 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 44 / 239 = 0.184 2024 Q1 T1 PHYSICS, MULTIDISCIPLINARY 14 / 114 = 0.123 2024 Q1 T1 ENERGY & FUELS 47 / 182 = 0.258 2024 Q2 T1 2.098 2024 Chemistry (miscellaneous) 2024 Q1 Energy (miscellaneous) 2024 Q1 Physics and Astronomy (miscellaneous) 2024 Q1 Materials Science (miscellaneous) 2024 Q1 Engineering (miscellaneous) 2024 Q1 12.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Momblona, Cristina Universidad de Zaragoza (orcid)0000-0003-2953-3065 Casas, Roberto Universidad de Zaragoza (orcid)0000-0001-5316-8171 Haro, Marta Universidad de Zaragoza (orcid)0000-0001-7246-2149 5008 785 Universidad de Zaragoza Dpto.
