Prof. C N R Rao Endowment Lecture
Lecture Title : Hybrid Organic-Inorganic Perovskite Halides and Related Materials (Click here for the poster)
Speaker Name : Prof. Anthony K. Cheetham
Date and Time : February 20, 2020 @ 4:00 p.m.
Venue : Faculty Hall, Main Building, IISc
Hybrid organic-inorganic perovskites are found in a number of important families, including the lead-based halides (e.g. CH3NH3PbI3) and the formates (e.g. [(CH3)2NH2]Zn(HCOO)3) , as well as systems with the ReO3 structure . The lead halides are attracting a great deal of current attention on account of their excellent performance as active layers in solar cells and other optoelectronic devices. Some of our recent work has focused on the search for lead-free hybrid double perovskites such as (CH3NH3)2AgBiBr6 and (CH3NH3)2KLnCl6 . Recent developments in this important area will be discussed, including the discovery of Cs2AgSbBr6  and a series of guanadinium-containing materials . We shall also describe some B-site vacant perovskites based on platinum and ruthenium , as well as recent developments in the area of hybrid layered double perovskite halides .
Brief Biography of Professor Sir Tony Cheetham :
Tony Cheetham is a Research Professor at the University of California, Santa Barbara, and a Distinguished Visiting Professor at the National University of Singapore. He was formerly the Goldsmiths’ Professor of Materials Science at the University of Cambridge (2007-2017) and the Treasurer and Vice-President of the Royal Society (2012-2017). He obtained his D.Phil. at Oxford in 1972 and did post-doctoral work in the Materials Physics Division at Harwell. He joined the Chemistry faculty at Oxford in 1974, and then moved to UC Santa Barbara in 1991 to become Professor in the Materials Department. From 1992-2004 he was the Director of UCSB’s Materials Research Laboratory.
Cheetham’s research has spanned both inorganic materials and metal-organic frameworks, and he has received numerous awards for his work. He is a member of the German National Academy of Sciences, the three Indian Academies of Sciences, the World Academy of Sciences (TWAS), and the American Academy of Arts and Sciences, among others, and holds honorary doctorates from several universities. In January 2020 he was knighted by the Queen for “Services to Materials Chemistry, UK Science and Global Outreach”.
