Researchers from the University of Sydney of the Schools of Physics, Aerospace and Chemical and Biomolecular Engineering, in collaboration with a metal matrix composite researcher of Shanghai Jiao Tong University, China, have suppressed Ionmigration in halid perovskites.
Their studyPublished in Science is progressingclaims that changing specific atoms on the B-site in Halogenide Perovskites can improve their stability. The researchers showed that strengthening atomic interactions reduces structural movement and limits Ionmigration.
They discovered that adding elements such as alkaline signal metals, such as calcium (CA) or Lanthanides (rare earth metals) such as Europe (EU) and Ytterbium (YB) to the B-site, was especially effective.
