- A study led by Bharat Ratna Professor C.N.R. Rao explores atomic rearrangements in lead iodide perovskites during phase transitions caused by temperature and pressure changes.
- Perovskite structure: perovskite refers to any material that has a crystal structure like the mineral perovskite. Ex: Lead Iodide Perovskites and calcium titanium Perovskites.
- Lead iodide perovskites exhibit excellent optoelectrical properties, making them promising materials for solar cells. However, their instability (decomposition in humid air) is a concern due to structural changes under varying conditions.
- Despite instability issues, it has commercial potential due to their unique crystalline structures and optoelectronic properties.
- Lead iodide perovskites’s energy conversion efficiency can be higher than even that of commercial silicon-based solar cells
- Addressing instability could lead to more efficient renewable energy generation using lead iodide perovskites in solar cells, LEDs, X-ray shielding, and Energy Storage Systems.
