In summary, perovskite is a new and promising field of research due to its high efficiency in power conversion, particularly in solar cells. However, verifying if a given material is a perovskite can be challenging without conducting complex lab experiments such as AFM, NMR, ESR, EPR, or XRD. Perovskite has a specific structure of ABX3, where A and B are cations and X is an anion. B is located in the corners of a cubic crystal, while X is placed in the octahedral position of B, and A is present in the cavity of the crystal. One

A perovskite is any material with a crystal structure following the formula ABX3, which was first discovered as the mineral called perovskite, which consists of calcium titanium oxide (CaTiO3)

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,

FAQ: How Can You Identify Perovskite in Solar Cells Without Advanced Lab Techniques?

What is perovskite?

Perovskite is a type of mineral that has the chemical formula ABX3, where A and B are cations and X is an anion. It is named after the Russian mineralogist, Lev Perovski, who first discovered it in the Ural Mountains.

Why is verification of perovskite important?

Verification of perovskite is important because it allows scientists to confirm the presence and composition of this mineral in various samples. This information is crucial for understanding the geological processes that formed the sample and can also provide insights into potential industrial or technological applications of perovskite.

How is perovskite verified?

Perovskite is typically verified through various analytical techniques, such as X-ray diffraction, electron microscopy, and spectroscopy. These methods allow scientists to identify the crystal structure, chemical composition, and physical properties of the mineral, which are all key factors in verifying its presence.

What are the potential applications of perovskite?

Perovskite has gained significant attention in recent years due to its potential applications in solar cells, LEDs, and other electronic devices. It has also shown promise in catalysis, sensors, and other industrial processes.

Are there any challenges in verifying perovskite?

Yes, there can be challenges in verifying perovskite, especially when it occurs in small quantities or as impurities in other minerals. In these cases, specialized techniques and careful sample preparation may be necessary to accurately identify and verify the presence of perovskite.
