126mA cm^(-2) J_(sc) from organic solar cells with a low-bandgap nonfullerene acceptor显示文摘Nonfullerene-based organic solar cells(NFOSCs)have received great interest recently due to their higher performance and greater potential compared with fullerene-based solar cells[1].Power conversion efficiencies(PCEs)over 13% have been realized in single-junction NFOSCs[2].Compared with traditional fullerene acceptors,the greatest advantage of nonfullerene acceptors is their stronger light-harvesting capability in the visible andZuo Xiao Xue Jia Dan Li Shizhe Wang Xinjian Geng Feng Liu Junwu Chen Shangfeng Yang Thomas P.Russell Liming Ding 2017Science Bulletin2017,62,22:28
2Synergistic effect of fluorination on both donor and acceptor materials for high performance non-fullerene polymer solar cells with 13.5% efficiency显示文摘A high performance polymer solar cells(PSCs) based on polymer donor PM6 containing fluorinated thienyl benzodithiophene unit and n-type organic semiconductor acceptor IT-4 F containing fluorinated end-groups were developed. In addition to complementary absorption spectra(300–830 nm) with IT-4 F, the PM6 also has a deep HOMO(the highest occupied molecular) level(-5.50 e V), which will lower the open-circuit voltage(V_(oc)) sacrifice and reduce the E_(loss) of the IT-4 F-based PSCs. Moreover, the strong crystallinity of PM6 is beneficial to form favorable blend morphology and hence to suppress recombination. As a result, in comparison with the PSCs based on a non-fluorinated D/A pair of PBDB-T:ITIC with a medium PCE of 11.2%, the PM6:IT-4 Fbased PSCs yielded an impressive PCE of 13.5% due to the synergistic effect of fluorination on both donor and acceptor, which is among the highest values recorded in the literatures for PSCs to date. Furthermore, a PCE of 12.2% was remained with the active layer thickness of up to 285 nm and a high PCE of 11.4% was also obtained with a large device area of 1 cm^2. In addition, the devices also showed good storage, thermal and illumination stabilities with respect to the efficiency. These results indicate that fluorination is an effective strategy to improve the photovoltaic performance of materials, as well as the both fluorinated donor and acceptor pair-PM6:IT-4 F is an ideal candidate for the large scale roll-to-roll production of efficient PSCs in the future.Qunping Fan Wenyan Su Yan Wang Bing Guo Yufeng Jiang Xia Guo Feng Liu Thomas P.Russell Maojie Zhang Yongfang Li 2018Science China Chemistry2018,61,5:18
3Host–Guest Molecular Recognition at Liquid–Liquid Interfaces显示文摘Host–guest molecular recognition at the liquid–liquid interface endows the interface with unique properties,including stimuli-responsiveness and self-regulation,due to the dynamic and reversible nature of non-covalent interactions.Increasing research efforts have been put into the preparation of supramolecular interfacial systems such as films and microcapsules by integrating functional components(e.g.,colloidal particles,polymers)at the interface,providing tremendous opportunities in the areas of encapsulation,delivery vehicles,and biphasic reaction systems.In this review,we summarize recent progress in supramolecular interfacial systems assembled by host–guest chemistry,and provide an overview of the fabrication process,functions,and promising applications of the resultant constructs.Beibei Wang Hao Chen Tan Liu Shaowei Shi Thomas P.Russell 2021Engineering2021,7,5:2
4界面稳定化策略实现长期稳定的反式钙钛矿太阳能电池显示文摘钙钛矿中卤素离子容易扩散穿透电荷传输层并腐蚀金属背电极,任何结构的钙钛矿太阳能电池因此都具有较差的器件稳定性.解决钙钛矿器件长期运行稳定性是实现其未来大规模商业化的关键因素之一.本文采用了一种电子传输侧界面稳定化策略,可以同时大幅提高器件效率和长期稳定性.该策略是在钙钛矿和富勒烯(C_(60))电子传输层之间引入了一种化学和光学更稳定的有机小分子电子传输材料Cl_(6)SubPc.它不仅起到了钝化钙钛矿表面的作用,还有效地抑制了卤素离子扩散.使用Cl_(6)SubPc/C_(60)复合电子传输层的器件可以获得22%的冠军光电转换效率和21.3%第三方认证效率,显著高于C_(60)单层参比器件效率.同时,器件在连续模拟太阳光照的条件下衰减至初始效率90%的时间(T_(90))达到2034h,暗态氮气氛围下7000h后仍维持初始效率的99%,氮气氛围里加热2000小时后依然保持初始效率的80%.另外,满足ISOS-O-1测试标准的户外稳定性T_(95)达到1272 h,更加严苛的双85稳定性测试T_(80)达到816 h.究其稳定机制,本文采用高分辨透射电子显微镜揭示了界面二维和三维钙钛矿晶粒的晶格近原子像,同时通过其附带的电子能量损失光谱原位成像了碘离子迁移确凿证据.进一步结合X射线光电子能谱、二次离子质谱以及密度泛函计算等手段揭示Cl_(6)SubPc中硼和氮原子与碘离子结合是阻挡碘离子迁移的关键原因.本文的研究结果将极大推动钙钛矿太阳能电池技术发展,使其技术商业化进程又向前迈进了坚实的一步.陈伟 韩兵 胡琴 谷猛 朱煜东 杨文强 周业城 罗德映 刘芳舟 程睿 朱瑞 馮憲平 Aleksandra B.Djurisic Thomas P.Russell 何祝兵 2021Science Bulletin2021,66,10:1

6Laser-Induced Recoverable Fluorescence Quenching of Perovskite Films at a Microscopic Grain Scale显示文摘Understanding the fundamental properties of metal-halide perovskite materials is driving the development of novel optoelectronic applications.Here,we report the observation of a recoverable laser-induced fluorescence quenching phenomenon in perovskite films with a microscopic grain-scale restriction,accompanied by spectral variations.This fluorescence quenching depends on the laser intensity and the dwell time under Auger recombination dominated conditions.These features indicate that the perovskite lattice deformation may take the main responsibility for the transient and show a new aspect to understand halide perovskite photostability.We further modulate this phenomenon by adjusting the charge carrier recombination and extraction,revealing that efficient carrier transfer can improve the bleaching resistance of perovskite grains.Our results provide future opportunities to attain high-performance devices by tuning the perovskite lattice disorder and harvesting the energetic carriers.Yuren Xiang Yameng Cao Wenqiang Yang Rui Hu Sebastian Wood Bowei Li Qin Hu Fan Zhang Jujie He Mozhgan Yavari Jinlai Zhao Yunlong Zhao Jun Song Junle Qu Rui Zhu Thomas P.Russell S.Ravi P.Silva Wei Zhang 2022Energy & Environmental Materials2022,5,4:0
7Synthesis and Characterization of Bionanoparticle-Silica Composites and Mesoporous Silica with Large Pores显示文摘A sol-gel process has been developed to incorporate bionanoparticles,such as turnip yellow mosaic virus,cowpea mosaic virus,tobacco mosaic virus,and ferritin into silica,while maintaining the integrity and morphology of the particles.The structures of the resulting materials were characterized by transmission electron microscopy,small angle X-ray scattering,and N2 adsorption desorption analysis.The results show that the shape and surface morphology of the bionanoparticles are largely preserved after being embedded into silica.After removal of the bionanoparticles by calcination,mesoporous silica with monodisperse pores,having the shape and surface morphology of the bionanoparticles replicated inside the silica,was produced,.This study is expected to lead to both functional composite materials and mesoporous silica with structurally well-defi ned large pores.Zhongwei Niu Saswat Kabisatpathy Jinbo He LAndrew Lee Jianhua Rong Lin Yang Godfrey Sikha Branko N.Popov Todd S.Emrick Thomas P.Russell Qian Wang 2009Nano Research2009,2,6:0
