Resumen: 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.
