| 1 | Non-fullerene acceptor fibrils enable efficient ternary organic solar cells with 16.6% efficiency显示文摘Optimizing the components and morphology within the photoactive layer of organic solar cells(OSCs)can significantly enhance their power conversion efficiency(PCE).A new A-D-A type non-fullerene acceptor IDMIC-4F is designed and synthesized in this work,and is employed as the third component to prepare high performance ternary solar cells.IDMIC-4F can form fibrils after solution casting,and the presence of this fibrillar structure in the PBDB-T-2F:BTP-4F host confines the growth of donors and acceptors into fine domains,as well as acting as transport channels to enhance electron mobility.Single junction ternary devices incorporating 10 wt%IDMIC-4F exhibit enhanced light absorption and balanced carrier mobility,and achieve a maximum PCE of 16.6%compared to 15.7%for the binary device,which is a remarkable efficiency for OSCs reported in literature.This non-fullerene acceptor fibril network strategy is a promising method to improve the photovoltaic performance of ternary OSCs. | Donghui Li Xiaolong Chen Jinglong Cai Wei Li Mengxue Chen Yuchao Mao Baocai Du Joel A.Smith Rachel C.Kilbride Mary E.O'Kane Xue Zhang Yuan Zhuang Pang Wang Hui Wang Dan Liu Richard A.L.Jones David G.Lidzey Tao Wang | 2020 | Science China Chemistry2020，63，10： | 0 |
| 2 | Influence of Halide Choice on Formation of Low-Dimensional Perovskite Interlayer in Efficient Perovskite Solar Cells显示文摘Recent advances in heterojunction and interfacial engineering of perovskite solar cells(PSCs)have enabled great progress in developing highly efficient and stable devices.Nevertheless,the effect of halide choice on the formation mechanism,crystallography,and photoelectric properties of the lowdimensional phase still requires further detailed study.In this work,we present key insights into the significance of halide choice when designing passivation strategies comprising large organic spacer salts,clarifying the effect of anions on the formation of quasi-2D/3D heterojunctions.To demonstrate the importance of halide influences,we employ novel neo-pentylammonium halide salts with different halide anions(neoPAX,X=I,Br,or Cl).We find that regardless of halide selection,iodide-based(neoPA)_(2)(FA)_((n-1))PbnI_((3n+1))phases are formed above the perovskite substrate,while the added halide anions diffuse and passivate the perovskite bulk.In addition,we also find the halide choice has an influence on the degree of dimensionality(n).Comparing the three halides,we find that chloride-based salts exhibit superior crystallographic,enhanced carrier transport,and extraction compared to the iodide and bromide analogs.As a result,we report high power conversion efficiency in quasi-2D/3D PSCs,which are optimal when using chloride salts,reaching up to 23.35%,and improving long-term stability. | Xueping Liu Thomas Webb Linjie Dai Kangyu Ji Joel A.Smith Rachel C.Kilbride Mozhgan Yavari Jinxin Bi Aobo Ren Yuanyuan Huang Zhuo Wang Yonglong Shen Guosheng Shao Stephen J.Sweeney Steven Hinder Hui Li David G.Lidzey Samuel D.Stranks Neil C.Greenham S.Ravi P.Silva Wei Zhang | 2022 | Energy & Environmental Materials2022，5，2： | 0 |
