Crystalline structure with a formula of A'A"B'B"O6A double perovskite is a crystalline structure with a formula of A'A"B'B"O61. It has the same architecture of 12 coordinate A sites and 6 coordinate B sites as perovskite, but two cations are ordered on the B site2. Double perovskites are known for their flexible structural, optical, and morphological properties due to their lattice framework3. They are more useful for hydrogen evolution due to their higher conduction band potential than simple perovskites3. Double perovskites are also used in solar cells4.Learn more:✕This summary was generated using AI based on multiple online sources.

The cation arrangement will differ based on charge, coordination geometry, and the ratio between A cation and B cation radii.en.wikipedia.org/wiki/PerovskiteThe double perovskite structure is so named because the unit cell of is twice that of perovskite. It has the same architeture of 12 coordinate A sites and 6 coordinate B sites, but two cations are ordered on the B site.www.princeton.edu/~cavalab/tutorials/public/struct…Double perovskites are known for their flexible structural, optical, and morphological properties due to their lattice framework having a general form AAʹBBʹO 6. They are more useful for hydrogen evolution due to their higher conduction band potential than simple perovskites.mnsl-journal.springeropen.com/articles/10.1186/s40…Chandran and his team took interest in a structure called ‘double perovskite’, which is essentially a three-dimensional extension of a single perovskite. The formula of a double perovskite is A2B2X6. Typically, solar cells have band gaps less than 2 eV (or electron-volt, the energy unit of subatomic particles).www.thehindubusinessline.com/business-tech/ne…Review An overview of double perovskites A2B′B″O6 with small ions at A site: Synthesis, structure and magnetic properties
