SUMMARY

Identifying perovskite materials in solar cells without advanced lab techniques is a significant challenge due to their complex structure, represented by the formula ABX3. Traditional methods such as Atomic Force Microscopy (AFM), Nuclear Magnetic Resonance (NMR), Electron Spin Resonance (ESR), Electron Paramagnetic Resonance (EPR), and X-ray Diffraction (XRD) are often impractical. Alternative methods include using a petrographic microscope for visual examination and X-ray Fluorescence (XRF) for chemical analysis. Understanding the crystal structure and properties of perovskites is crucial for their application in high-efficiency solar cells.

PREREQUISITES
  • Understanding of perovskite crystal structure (ABX3)
  • Familiarity with X-ray Fluorescence (XRF) techniques
  • Knowledge of petrographic microscopy
  • Basic principles of X-ray Diffraction (XRD)
NEXT STEPS
  • Research the use of petrographic microscopy for material identification
  • Learn about X-ray Fluorescence (XRF) for chemical composition analysis
  • Study X-ray Diffraction (XRD) techniques for structural confirmation
  • Explore the properties and applications of perovskite materials in solar technology
USEFUL FOR

Researchers, material scientists, and solar energy engineers interested in identifying and utilizing perovskite materials for high-efficiency solar cells.

TL;DR
perovskite is a new field of research due to it's high efficiency, but how you verify a given material is perovskite without doing complex lab experiment like AFM,NMR,ESR,EPR, XRD
perovskite is a new field of research due to it's high efficiency in power conversion in solar cell, but how you verify a given material is perovskite without doing complex lab experiment like AFM,NMR,ESR,EPR, XRD. It has a structure of ABX_3. where A,B are cation, X is anion. B are placed in corner of cubic crystal and X are placed in octahedral position of B and A are present in the cavity of crystal. One can google more for knowing property and structure

perovskite is a new field of research
Thought it was a mineral.

The lowest tech method would be to examine the material under a petrographic microscope.
Consider also XRF to identify the chemistry, or powder x-ray diffraction to confirm the structure.

Can you say more about why you are asking this question? Are you mining it and want to be sure of the purity so you can set your selling price? Or are you buying it for some purpose and similarly want to determine the purity to be sure you are comfortable with the selling price?
 
I suspect the OP is referring the group of oxide material with a perovskite structure, rather than the actual mineral.
Perovskites were a hot topic for research back in the day since most high temperature superconductors have a perovskite structure (most famously YBCO).
In recent years solar cells made from perovskite have turned out to be very efficient, meaning this class of material is now back in the limelight,. I suspect it is the latter the OP has been reading about.
Also, mostly this refers to perovskite thin-films; not bulk materials.

The standard method for checking the structure of a perovskite film (as used for e.g. PVs) would be XRD; all other methods that I know of are more complicated (e.g. TEM). I seriously doubt there is a cheap way to check the structure,
