The widespread deployment of perovskite solar cells (PSCs) or other emergent PV technologies as a sustainable energy solution hinges critically on both their operational stability and the ability to efficiently extract maximum power under real-world illumination conditions. While significant advances have been made in PSC stability, particularly in triple-mesoscopic hole-transport-material-free architectures, conventional maximum power point tracking (MPPT) algorithms fall short when applied to these highly stable but hysteretic devices. This presentation introduces a novel galvanostatic power-tracking algorithm specifically designed to overcome the challenges posed by high-hysteresis PSCs, complemented by comprehensive real-world performance data.
Our approach utilizes cost-effective hardware[1,2] that enables parallel long-term stability measurements, addressing a critical gap in PSC characterization methodology. The system's architecture allows for continuous monitoring and precise power optimization, particularly crucial for devices incorporating power optimizers. We will present detailed performance metrics from extended outdoor testing, demonstrating the algorithm's superior tracking efficiency compared to traditional methods. The real-world data encompasses various environmental conditions, validating the system's robustness and reliability in actual operational scenarios. This work contributes to the broader goal of PSC commercialization by providing a practical solution for accurate power tracking, essential for both research and commercial applications.
Our findings have significant implications for the integration of PSC technology into various applications, including building-integrated photovoltaics (BIPV) and large-scale solar installations, where accurate power optimization is crucial for maximum energy yield. The combination of our innovative tracking methodology and real-world validation data provides valuable insights into the practical implementation of PSC technology, addressing key challenges in stability assessment and performance optimization for sustainable photovoltaic applications.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
