    Two papers from Xiaowei Zhan group were selected as "100 most-impact international papers of China in 2016"

  • On October 31, 2017, Institute of Scientific and Technical Information of China (ISTIC) released statistical data of Chinese S&T papers in 2016. Two papers from Xiaowei Zhan group in the College of Engineering were selected as "100 most-impact international papers of China in 2016", which were 1) High-Performance Electron Acceptor with Thienyl Side Chains for Organic Photovoltaics (J. Am. Chem. Soc., 2016, 138, 4955−4961) and 2) A Facile Planar Fused-Ring Electron Acceptor for As-Cast Polymer Solar Cells with 8.71% Efficiency (J. Am. Chem. Soc., 2016, 138, 2973−2976). These two papers were cited by 245 and 204 times, respectively, and were selected as ESI Hot Paper and ESI Highly Cited Paper.

    Last year, another paper from this group was selected as "100 most-impact international papers of China in 2015": An Electron Acceptor Challenging Fullerenes for Efficient Polymer Solar Cells (Adv. Mater., 2015, 27, 1170–1174). This paper was cited by 438 times, and was selected as ESI Hot Paper and ESI Highly Cited Paper.

    All these works reported important progress in fused-ring electron acceptors (FREAs) for organic photovoltaics (OPV).

    In 2015, Zhan group firstly proposed the concept of “FREA”, created brand-new nonfullerene acceptor materials system, designed and synthesized a series of high-performance FREAs, and fabricated high-efficiency OPV devices. ITIC invented by Zhan group becomes a star molecule in OPV field, and FREA is the best nonfullerene acceptor materials system.

    Now FREAs designed by Zhan group are commercial available. Around 50 well-known research groups across the world have already utilized these FREAs to fabricate high-efficiency OPV, which are superior to OPV based on fullerene acceptors.

    The original works from Zhan group have attracted extensive attention and follow-up in this field, and have been leading the development of nonfullerene acceptor field for 10 years.
