    Three papers of Xiaowei Zhan’s group selected as "the 100 most influential international papers in China" in 2017

  • The Institute of Scientific and Technical Information of China released the statistics of 2017 China science and technology papers on Nov 1, 2018. According to the statistical results, a total of 8 papers of Peking University were selected into the "100 most influential international papers in China" in 2017, among which 3 were from Prof. Xiaowei Zhan’s research group in College of Engineering. From 2015 to 2016, three papers were also selected from Zhan's group.

    Zhan's group has made pioneering and leading contributions in the field of non-fullerene acceptor solar cells. In particular, since 2015, they have proposed the new concept of "Fused-Ring Electron Acceptor (FREA)", and invented the star molecule ITIC. Their original work has attracted extensive attention and follow-up from domestic and foreign counterparts, with 130 research groups using the ITIC family. Over the past three years, the efficiency of non-fullerene organic solar cells has soared from less than 7% to more than 17%, much higher than that of the fullerene system, thanks to the invention of the ITIC family. Since then, organic solar cells have begun to marginalize previously predominant fullerene acceptors, inaugurating a new era---the non-fullerene era.
