ABX3 (e.g. CH3NH3PbI3)
ChemistryPerovskita is specified as ABX3 (e.g. CH3NH3PbI3). Density band thin-film.
What holds Perovskita together is not the nickname. Formula ABX3 (e.g. CH3NH3PbI3), density thin-film.
Meters are atlas-relative. Grades are the SKUs buyers write.
Fases
Microstructure
OrderProcessing sets grain, crystallinity or fibre orientation — the reason two lots of Perovskita can test differently.
Interfaces
SurfacesCoatings, oxide films, sizings or paper faces often decide weather and fire behaviour more than the bulk brochure.
Defects
FlawsInclusions, voids, knots, pinholes or residual stress start the failures that mill certificates do not list.
Grades
VariantsPerovskita is a family. Grade names below are the ones buyers actually write on RFQs.
Ageing
TimeMoisture, UV, creep, hydrogen or carbonation shift properties in service. Design to the aged state.

Perovskita holds together by ionic/covalent networks.
Secondary forces
Hydrogen bonds, van der Waals stacks or grain-boundary cohesion set toughness and moisture uptake.
Composites & fills
Fillers, fibres, plasticisers or aggregates are part of the real product, not impurities.
Environment film
Oxides, chars, sizings or paints are the layer the world actually meets.
Change the grade, the coating or the moisture and you have a different material with the same English name.
