Preprint: Enhanced Power Point Tracking for High Hysteresis Perovskite Solar Cells: A Galvanostatic
This article introduces a novel Maximum Power Point Tracking (MPPT) algorithm and cost-effective hardware for long-term operational stability measurements in perovskite solar cells (PSCs). Harnessing the untapped potential of solar energy sources is crucial for achieving a sustainable future, and accurate MPPT is vital to maximizing power generation. However, existing MPPT algorithms for classical photovoltaic technology lead to suboptimal performance and decreased energy efficiency conversion when applied to the most stable perovskite devices, the so-called triple mesoscopic hole transport material (HTM)-free metal halide PSCs. To address this challenge, our research focuses on developing an innovative low-cost hardware solution for research purposes that enables massive long-term stability measurements, eliminating the need for expensive and complex stability monitoring systems. Our galvanostatic MPPT algorithm ensures continuous and precise tracking achieving superior operational performance for high hysteresis PSCs. The suggested enhancements bear significant implications for the extensive integration of perovskite solar cell technologies, particularly those dependent on power optimizer devices.
