Perovskite (PV) in 2020s: Lead sequestration · 569

ABX3 halide crystals that jumped laboratory solar efficiency — still fighting humidity, lead and lifetime. Perovskite (PV) is one of 32 materials in this atlas, grouped under advanced: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.

Scores compare Perovskite (PV) with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates. Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.

Perovskite (PV) (ABX3 (e.g. CH3NH3PbI3)) is a family of grades whose density thin-film, heat band soft lattices; heat-sensitive, and fire letter device, not a building class. Perovskite (PV) is sold as grades, not as a single substance. Chemistry ABX3 (e.g. CH3NH3PbI3), density thin-film, heat band soft lattices; heat-sensitive.
