报告人简历
Prof. Lioz Etgar obtained his Ph.D. (2009) at the Technion-Israel Institute of Technology and completed post-doctoral research with Prof. Michael Grätzel at EPFL, Switzerland. In his post-doctoral research, he received a Marie Curie Fellowship and won the Wolf Prize for young scientists. Since 2012, he has been a senior lecturer in the Institute of Chemistry at the Hebrew University. In 2017, he received an Associate Professor position. Prof. Etgar was the first to demonstrate the possibility to work with the perovskite as light harvester and hole conductor in the solar cell which result in one of the pioneer publication in this field. Recently, Prof. Etgar won the prestigious Krill prize by the Wolf foundation. Etgar’s research group focuses on the development of innovative solar cells. He has published about 60 articles in prestigious international journals (including Adv. Mater., Adv. Funct. Mater., Angew. Chem. Int. Ed., J. Am. Chem. Soc. Etc).

报告摘要
In this talk, Prof. Etgar will discuss their recent work on (1) stability of excitons in quantum wells, which is greatly enhanced due to the confined effect and the coulomb interaction. The exciton binding energy of the typical 2D organic-inorganic perovskites is up to 300 meV and their self-assembled films exhibit bright photoluminescence at room temperature. (2) the use of 2D perovskite in high efficiency solar cells. The 2D perovskite structure should provide stable perovskite structure compare to the 3D structure. The additional long organic cation, which is added to the perovskite structure (in the 2D structure), is expected to provide hydrophobicity, which will enhance the resistivity of the perovskite to humidity. (3) the synthesis and characterization of perovskite NPs- i.e. inorganic and hybrid organic-inorganic NPs. New nanostructures such us: NRs and NWs will be presented and the introduction of other cations such us Rb will be shown.
