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.2024http://zaguan.unizar.es/record/13330510.1016/j.xcrp.2024.101885http://zaguan.unizar.es/record/133305oai:zaguan.unizar.es:133305info:eu-repo/grantAgreement/ES/AEI/PID2020-116011RB-C22info:eu-repo/grantAgreement/ES/DGA/E31-20Rinfo:eu-repo/grantAgreement/ES/DGA/T27-23Rinfo:eu-repo/grantAgreement/ES/UZ-DGA/T57-23Rinfo:eu-repo/grantAgreement/ES/MICINN AEI/EIN2020-112315info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-107893RB-I00/AEI-10.13039-501100011033info:eu-repo/grantAgreement/ES/MCIU/IJC-2020-044684-Iinfo:eu-repo/grantAgreement/ES/MICINN/PID2019-108247RA-I00info:eu-repo/grantAgreement/ES/MICINN/PID2022-140516OB-I00info:eu-repo/grantAgreement/ES/MICINN/RYC-2018-025222-ICell Reports Physical Science 5, 3 (2024), 101885 [21 pp.]byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
