Understanding defect passivation mechanisms (Lewis acid-base interactions, weak molecular interactions) and crystallization kinetics is crucial for feature engineering in ML models. Specific molecular descriptors like HBD/HBA counts, LogP, TPSA, and MACCS bonds are quantitative proxies for these behaviors, enabling efficient screening.
High-fidelity, standardized data (Perovskite Database Project) is vital. Molecular structures are converted into numerical descriptors (SMILES, MACCS Keys) or graph representations for ML. Ensemble learning (RF, GBDT) and deep learning (GNN) are used for screening, with active learning (Bayesian Optimization) for process optimization.
Explainable AI (SHAP) helps reveal underlying chemical logic, showing how molecular flexibility impacts passivation. Scientific Machine Learning (SciML) embeds physics-driven laws into models, while Machine Learning Interatomic Potentials (MLIPs) accelerate atomic-scale simulations for defect dynamics.
Generative models (VAEs, GANs) enable inverse design by navigating latent spaces to propose novel molecular structures. Large Language Models (LLMs) like Perovskite-LLM extract domain knowledge. Coupled with robotic platforms (PASCAL), this leads to Self-Driving Laboratories for closed-loop autonomous discovery.
