报告题目:Designing Novel Organic Small Molecular as Electron Transport Layers for Planar Perovskite Solar Cells

报告人:   Qichun Zhang

                  Nanyang Technological University Singapore.

报告时间:2019325日(星期一)上午9:30

报告地点:吉林大学中心校区物理楼333报告厅

报告简介:

Compared to the traditional-architecture perovskite photovoltaics (n-i-p type), which use metal oxide as electron transport layers(ETLs) and organic semiconducting materials as hole transport layers, the fabrication of metal-oxide-free, solution-processed inverted perovskite solar cells (PSCs, Figure 1) is more desired because of low-temperatures and all-solution-based applications in future commercial PSC modules. In a typical configuration of inverted PSCs, the widely used ETL compound is the fullerene-based phenyl-C61-butyric acid methyl ester (PCBM), which currently is the best organic ETL material. The cost of this compound is very high, and the morphology and electrical properties are very sensitive to experimental conditions. In this talk, I will talk the recent progress of new organic ETL materials in my group for the replacement of PCBM in inverted PSCs. We believe that easily-accessible simple n-type small molecules are promising ETL candidates to further propel inverted PSCs to practical applications.

Then, he joined Prof. Kanatzidis’ group at Northwestern University as a Postdoctoral Fellow (Oct. 2007 –Dec. 2008). Since Jan. 2009, he joined School of Materials Science and Engineering at Nanyang Technological University (NTU, Singapore) as an Assistant Professor. On Mar 1st, 2014, he has promoted to Associate Professor with tenure and on Dec 1st, 2014, he became an adjunct Associate Professor at Division of Chemistry and Biological Chemistry, School of Physical and Mathematical Sciences, Nanyang Technological University. Besides these, he also has three-year working experience in research institute of Nanjing Chemical Industry Co. (Aug. 1992 – Aug. 1995) and two-year’s research experience in ICCAS (Aug. 1998 – Jun 2000). He received TCT fellowship in 2013 and lectureship from National Taiwan University in 2014. Currently, he is an associate editor of J. Solid State Chemistry, the Advisory board member of Journal of Materials Chemistry C, the International Advisory Board member of Chemistry – An Asian Journal, the Advisory board member of Materials Chemistry Frontiers, and the Advisory board member of Inorganic Chemistry Frontiers. Also, he is Guest Editor of Inorganic Chemistry Frontiers (2016-2017), Guest Editor of Journal of Materials Chemistry C (2017-2018), and Guest Editor of Inorganic Chemistry Frontiers (2017-2018). In 2018, he has been recognized as one of highly-cited researchers (top 1%) in cross-field in Clarivate Analytics.  Currently, he is a fellow of the Royal Society of Chemistry. He has published > 315 papers and 4 patents (H-index: 64, Total citation >13500).
