The performance of metal halide perovskite solar cells (PSCs) is strongly influenced by various experimental parameters, including material compositions, device architectures, and fabrication processes. Although substantial experimental efforts have been devoted to improving device efficiency and stability, the systematic organization and utilization of accumulated experimental data remain challenging, particularly in individual research laboratories. Herein, we establish a structured experimental dataset comprising over 1,000 PSC devices fabricated in a single research laboratory, incorporating detailed information on material compositions, device structures, fabrication conditions, and photovoltaic characteristics. To ensure data consistency and reliability, the collected experimental records are systematically cleaned, standardized, and transformed into machine-readable features for machine learning (ML) analysis. Various ML algorithms are employed to predict key photovoltaic performance parameters, including power conversion efficiency (PCE), open-circuit voltage (Voc), short-circuit current density (Jsc), and fill factor (FF), from material properties and fabrication conditions. Furthermore, Shapley additive explanations (SHAP) are utilized to identify the experimental parameters that contribute most strongly to the predicted device performance and to investigate their influence on photovoltaic characteristics. Based on these findings, targeted experiments are designed to evaluate the effects of the identified parameters and experimentally validate the ML-derived insights. This study aims to demonstrate an integrated approach combining systematic experimental data collection, ML-based performance prediction, interpretable feature analysis, and experimental validation, providing a foundation for data-driven optimization of high-performance PSCs.
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.
