Strength band
not a structural material — a semiconductor film
Perovskite (PV) · ABX3 halide crystals that jumped laboratory solar efficiency — still fighting humidity, lead and lifetime.
Darker cells mean a higher score for this topic on that metric.

Declared reaction class in this atlas: device, not a building class. Assemblies still need resistance tests.
Thermal mark 8/100 versus the atlas. Conductivity note: modest; not an insulator product.
thin-film
Origin story: Miyasaka 2009 DSSC; 2012 solid-state jump (Japan / Oxford / Korea).
Circularity mark 40/100 — editorial, route-specific.

Numbers below are bands used by working engineers, not live quotes. Tensile note: not a structural material — a semiconductor film.
Fire performance in this atlas is editorial. Real projects need the assembly report.
not a structural material — a semiconductor film
Modulus follows chemistry and orientation — not the marketing nickname.
Crack growth, not peak stress, retires most real parts.
Cyclic and time-dependent damage dominate certificates issued on static coupons.
Indentation, drape or compressive class — whichever the trade actually measures.
modest; not an insulator product — Perovskite (PV) is not a substitute for a dedicated λ layer.
Melting / softening / decomposition band: soft lattices; heat-sensitive.
Joints and clearances must follow the expansion class of Perovskite (PV), not of steel-by-habit.
Density thin-film sets how fast a section changes temperature.
Foams, VIPs and moist batts drift; quote aged values.
Perovskite (PV) is generally a dielectric or semiconductor film, not building wire.
Fillers and moisture change resistivity more than brochures admit.
IACS, volume resistivity or dielectric strength — pick the quantity the job uses.
Typical declared class: device, not a building class. This is not a universal passport.
Euroclass is reaction. EI/R ratings are assemblies — boards, coats, cavities.
Perovskite (PV) can burn or drip; do not treat it as A1 without a system test.
CO, HCN, HF or fibres — the species depend on chemistry. Name the test (ISO 5659, EN 45545, NFPA 1971).
If a salesperson quotes a single “safety score”, ask which standard, which thickness, which year.
Polymer-derived filaments with graphite-like sheets — aero, bikes and a fire story that is about the resin, not the fibre.
Overall 49 ⬡A one-atom carbon sheet — Nobel-era physics, composites hype, and a few honest electronics and barrier uses.
Overall 50 ☁️A nanoscale silica sponge — among the lowest solid λ values, fragile unless blanketed, and A1 when purely inorganic.
Overall 60 🩺Near-equiatomic Ni–Ti that remembers shape and super-elasticates — stents, orthodontics and actuators.
