New protocol improves ML evaluation for perovskite solar cells

A new protocol for evaluating machine learning models in perovskite photovoltaics has been developed to address the issue of data duplication in existing random splitting methods. This provenance-grouped protocol progressively isolates duplicate devices, publications, and institutions, providing a more rigorous assessment of true physical generalization. Benchmarking thirteen models revealed that while tree ensembles perform well on familiar data, neural architectures excel when evaluating genuinely unseen data and future discoveries, highlighting the importance of device architecture and fabrication methodology alongside absorber chemistry. AI

IMPACT Establishes a more rigorous standard for ML model evaluation in materials science, potentially accelerating discovery by distinguishing true generalization from data memorization.

    Provenance-grouped protocol for evaluating machine learning in perovskite photovoltaics

    arXiv:2610.12766v1 Announce Type: new Abstract: Machine-learning models for perovskite solar cells are typically evaluated using random data splits, which we show systematically leak information through massive internal duplication. Because nearly two-thirds of curated devices sh…
