Perovskite Nanocrystal

Why in the news?                        

Recently, researchers at the Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru have developed an innovative method to minimize anion migration in CsPbX₃ perovskite nanocrystals.

About Perovskite Nanocrystal:

• It is a material that has the same crystal structure as the mineral calcium titanium oxide (CaTiO3).  
• Generally, perovskite compounds have a chemical formula ABX3, where ‘A’ and ‘B’ represent cations, and X is an anion that bonds to both.
• A large number of different elements can be combined together to form perovskite structures.
• Due to its compositional flexibility, scientists can design perovskite crystals to have a wide variety of physical, optical and electrical characteristics from insulating, semiconducting, metallic and superconducting characteristics.

Applications of Perovskite Nanocrystal:

• • They have applications in various fields of optoelectronics, including photovoltaic solar cells, photodetectors, light-emitting devices,
  • Perovskite LEDs, which combine the advantages of OLEDs and QLEDs, have long been considered a promising technology for next-generation lighting.
