Perovskite crystals harvest sunlight almost as well as silicon, but cost pennies. Their trouble is an inborn fragility: from warmth and ordinary water in the air, they “get sick.” Inside, disorder builds up, and the shiny plate turns cloudy, losing its abilities within a couple of days.
Artificial intelligence becomes a diagnostic doctor. It performs spectroscopy — shining a light beam through the crystal and spotting micro-cracks before they appear. Then it sifts through thousands of additive recipes and finds a “medicine”—tiny particles that stitch up the lattice’s weak spots. In one experiment, the algorithm suggested embedding gold droplets, and the material lasted ten times longer.
A review of research showed: AI’s main talent is linking scattered observations into a sharp forecast. Already, such panel cells run trouble-free for thousands of hours, and in the future, algorithms will take over routine testing to speed up production.

Three-dimensional all-inorganic halide perovskites, represented by CsPbX$$_3$$ (X = Cl, Br, I), have attracted broad interest in photovoltaics, photodetectors, and light-emitting devices because of their outstanding optoelectronic properties. Their practical deployment, however, remains limited by instability under thermal, chemical, optical, and electrical stress. Conventional studies have established important experimental and theoretical foundations, but they still struggle with multimodal data, coupled degradation pathways, protocol dependence, sparse statistics, and uncertainty quantification. Artificial intelligence (AI) offers a practical route to address these limitations. This review summarizes recent progress in AI-assisted studies of instability in 3D CsPbX$$_3$$ and organizes the discussion around four linked tasks, including stability discrimination and diagnosis, microscopic mechanism analysis, consequence and reliability modeling, and engineering stability enhancement. We further discuss the main limitations of current methods, especially in data quality, protocol consistency, benchmark design, interpretability, and transferability across domains. Finally, we outline future directions for the field, including standardized data infrastructures, interpretable cross-scale models, and tighter integration of AI with automated experiments and physics-based modeling. The aim of this review is to provide a coherent and practically useful framework for researchers seeking to use AI to understand, predict, and mitigate instability in inorganic perovskites.
Lev Perovsky collected minerals and never suspected his name would go down in physics history: the mineral he discovered now inspires the creation of cheap solar energy.
