| 3 | Passivation agent with dipole moment for surface modification towards efficient and stable perovskite solar cells显示文摘Recently,there has been renewed interest in interface engineering as a means to further push the performance of perovskite solar cells closer to the Schockly-Queisser limit.Herein,for the first time we employ a multi-functional 4-chlorobenzoic acid to produce a self-assembled monolayer on a perovskite surface.With this interlayer we observe passivation of perovskite surface defects and a significant suppression of non-radiative charge recombination.Furthermore,at the surface of the interlayer we observe,charge dipoles which tune the energy level alignment,enabling a larger energetic driving force for hole extraction.The perovskite surface becomes more hydrophilic due to the presence of the interlayer.Consequently,we observe an improvement in open-circuit voltage from 1.08 to 1.16 V,a power conversion efficiency improvement from 18%to 21%and an improved stability under ambient conditions.Our work highlights the potential of SAMs to engineer the photo-electronic properties and stability of perovskite interfaces to achieve high-performance light harvesting devices. | Ge Wang Chen Wang Yajun Gao Shanpeng Wen Roderick C.I.MacKenzie Liuxing Guo Wei Dong Shengping Ruan | 2022 | Journal of Energy Chemistry2022，31，1： | 1 |

| 9 | Cu nanowire array with designed interphases enabling high performance Si anode toward flexible lithium-ion battery显示文摘To meet the growing demand for wearable smart electronic devices,the development of flexible lithium-ion batteries(LIBs)is essential.Silicon is an ideal candidate for the anode material of flexible lithium-ion batteries due to its high specific capacity,low working potential,and earth abundance.The largest challenge in developing a flexible silicon anode is how to maintain structural integrity and ensure stable electrochemical reactions during external deformation.In this work,we propose a novel design for fabricating core–shell electrodes based on a copper nanowire(CuNW)array core and magnetron sputtered Si/C shell.The nanowire array structure has characteristics of bending under longitudinal stress and twisting under transverse stress,which helps to maintain the mechanical stability of the structure during electrode bending and cycling.The low-temperature annealing generates a small amount of Cu3Si alloy,which enhances the connection strength between Si and the conductive network and solves the poor conductivity problem of Si,which is known as a semiconductor material.This unique configuration design of CuNW@Si@C-400℃ leads to stable long cycle performance of 1109 mAh∙g^(-1) after 1000 cycles and excellent rate performance of 500 mAh∙g^(-1) at a current density of 10 A∙g^(-1).Furthermore,the CuNW@Si@C-400℃||LiFePO_(4)(LFP)full battery demonstrates excellent flexibility,with a capacity retention of more than 96%after 100 bends.This study provides a promising strategy for the development of flexible lithium-ion batteries. | Pengfei Su Ziqi Zhang Linshan Luo Zhiyong Zhang Chaofei Lan Yahui Li Shaowen Xu Shanpeng Pei Guangyang Lin Cheng Li Xiang Han Wei Huang Songyan Chen | 2024 | Nano Research2024，17，3： | 0 |
| 10 | Surface energy-driven solution epitaxial growth of anatase TiO2 homostructures for overall water splitting显示文摘Titanium dioxide(TiO2)has been extensively investigated as a photocatalyst for water splitting to produce H2.However,an overall water splitting by using anatase TiO2 is extremely difficult due to the short lifetime of holes.In this work,we propose that a surface energy decrease from{001}to{101}of anatase TiO2 is able to drive an epitaxial growth.A novel anatase TiO2 homostructure has been successfully synthesized via a facile hydrothermal route,where{101}semi-pyramid nanoparticles epitaxially grew on the both sides of the{001}nanosheets.The epitaxial relationship between the nanoparticles and the nanosheets has been characterized to be{001}//{001}of anatase TiO2.For the first time,it is interesting to find that the homostructure with 12 wt%of{101}semi-pyramid can significantly improve the H2 evolution rate by nearly 5 times compared to the pure nanosheets under the ultraviolet irradiation.More importantly,such homostructure enables 10.78μmol g-1h-1 of O2 production whereas the pure nanosheets cannot evolve detectable O2 gas.Meanwhile,the time-resolved photoluminescence analysis indicates that the mean lifetime of the holes is increased from 2.20 ns of the nanosheets to 3.59 ns of the homostructure,accounting for the observed overall water splitting.The findings suggest that constructing a homostructure by a surface energy strategy could be promising towards overall water splitting,which may be applicable to other photocatalytic materials. | Shi Li Luoyuan Ruan Shanpeng Wang Zhiyu Wang Zhaohui Ren Gaorong Han | 2020 | Journal of Materials Science & Technology2020，42，11： | 0 |
| 11 | Effects of BTA2 as the third component on the charge carrier generation and recombination behavior of PTB7:PC71BM photovoltaic system显示文摘Effects of a benzotriazole(BTA)-based small molecule,BTA2,as the third component on the charge carrier generation and recombination behavior of poly[[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl]](PTB7):[6,6]-phenyl-C71-butyric acid methyl ester(PC71BM)organic solar cells(OSCs)were investigated by optical simulation of a transfer matrix model(TMM),photo-induced charge extraction by linearly increasing voltage(photo-CELIV)technique,atomic force microscope(AFM),and the Onsager–Braun model analysis.BTA2 is an A_(2)-A_(1)-D-A_(1)-A_(2)-type non-fullerene small molecule with thiazolidine-2,4-dione,BTA,and indacenodithiophene as the terminal acceptor(A_(2)),bridge acceptor(A_(1)),and central donor(D),respectively.The short-circuit current density of the OSCs with BTA2 can be enhanced significantly owing to a complementary absorption spectrum.The optical simulation of TMM shows that the ternary OSCs exhibit higher internal absorption than the traditional binary OSCs without BTA2,resulting in more photogenerated excitons in the ternary OSCs.The photo-CELIV investigation indicates that the ternary OSCs suffer higher charge trap-limited bimolecular recombination than the binary OSCs.AFM images show that BTA2 aggravates the phase separation between the donor and the acceptor,which is disadvantageous to charge carrier transport.The Onsager-Braun model analysis confirms that despite the charge collection efficiency of the ternary OSCs being lower than that of the binary OSCs,the optimized photon absorption and exciton generation processes of the ternary OSCs achieve an increase in photogenerated current and thus improve power conversion efficiency. | Leijing Liu Hao Zhang Bo Xiao Yang Liu Bin Xu Chen Wang Shanpeng Wen Erjun Zhou Gang Chen Chan Im Wenjing Tian | 2021 | Frontiers of Chemical Science and Engineering2021，15，1： | 0 |
| 12 | Abnormal grain growth behavior and mechanism of 6005A aluminum alloy extrusion profile显示文摘Peripheral coarse grain(PCG)structure is a common microstructural defect appearing in the aluminum alloy extrusion process,which seriously affects the mechanical properties of the profiles.In this work,a series of extrusion experiments and numerical simulations were conducted to investigate the influence of billet temperature and ram speed on the microstructure,mechanical properties and thickness of PCG layers of 6005A aluminum alloy profiles.The mechanism of abnormal grain growth(AGG)occurring on the surface and in the core of profiles was revealed.The result showed that lower ram speed could sup-press the formation of coarse grains.The AGG on the surface of the profiles was activated by the shear deformation and lattice distortion derived from the friction on the interface between the profile and die.When the billet was heated to a relatively high temperature,dynamic recrystallization(DRX)was dominant,and the Cube{100}<100>and R-Cube{100}<110>grains underwent abnormal growth to form surface coarse grains.When the billet was heated to a relatively low temperature,the degree of static recrystallization(SRX)became stronger,and the Goss{110}<100>and R-Cube{100}<110>grains under-went abnormal growth to form surface coarse grains.The AGG in the core of profiles was activated by the large grain boundary misorientation and a strain gradient formed because the Cube{100}<100>re-crystallized grains were surrounded by the Copper{112}<111>and Brass{110}<112>deformed grains.The second phases in the 6005A aluminum alloy extrusion profiles were mainlyβ(Mg_(2) Si)and AlFeMnCrSi.As the billet temperature increased,moreβphases dissolved into the aluminum matrix,thus enhancing the strength and hardness of the profiles.As the ram speed decreased,the thickness of PCG layers reduced,thus resulting in higher strength and hardness of the profiles.Due to the integrated effect of solution strengthening and grain refinement strengthening mechanisms,the combination of extrusion parameters for the profile to obtain the best mechanical properties was determined as 540℃×0.5 mm/s. | Haixiao Zhao Lu Sun Guoqun Zhao Junquan Yu Fei Liu Ximan Sun Zhengfeng Lv Shanpeng Cao | 2023 | Journal of Materials Science & Technology2023，，26： | 0 |
| 13 | Numerical Analysis of the Influence of Turbulence Intensity on Iced Conductors Gallop Phenomena显示文摘Turbulence is expected to play a relevant role in the so-called conductor gallop phenomena,namely,the high-amplitude,low-frequency oscillation of overhead power lines due to the formation of ice structures and the ensu-ing effect that wind can have on these.In this work,the galloping time history of a wire with distorted(fixed in time)shape due to the formation of ice is analyzed numerically in the frame of afluid-solid coupling method for different wind speeds and levels of turbulence.The results show that the turbulence intensity has a moderate effect on the increase of the conductor’s aerodynamic lift and drag coefficients due to ice accretion;nevertheless,the corresponding changes in the torsion coefficient are very significant and complicated.A high turbulence intensity can affect the torsion coefficient in a certain range of attack angles and increase the torsion angle of the conductor.Through comparison of the galloping phenomena for different wind velocities,it is found that the related amplitude grows significantly with an increase of the wind speed.For a relatively large wind speed,the galloping amplitude is more sensitive to the turbulence intensity.Moreover,the larger the turbulence intensity,the larger the conductor’s vertical and horizontal galloping amplitudes after icing.The torsion angle also increases with an increase in the wind speed and turbulence intensity. | Yuantao Liu Yanzhe Li Shanpeng Zhao Youpeng Zhang Taizhen Zhang | 2023 | Fluid Dynamics & Materials Processing2023，19，10： | 0 |
| 14 | Non-Halogenated Solvent-Processed High-Efficiency Polymer Solar Cells:the Role of Diphenyl Ether in Morphology,Light-Trapping,Transport Properties显示文摘There is an urgent need to use green non-halogenated solvents to prepare polymer solar cells(PSCs) for industrialization.It is time-consuming but necessary to find a suitable non-halogenated solvent/additive combination for a given donor:acceptor materials system.In this research,we report a non-halogenated binary solvent system toluene/diphenyl ether(DPE) for the PBDTT-DTffBT:PC_(71)BM and PM6:Y6 blending systems that exhibit comparable power conversion efficiency(PCE) to that of devices prepared with halogenated solvents.The nano scale morphology indicates that blending film processed solely with toluene has poor phase segregation and a rough surface,which hinders charge separation and interfacial contact.Besides,the total absorption spectra revealed significant light-trapping losses in the toluene-processed solar cells,resulting in low photocurrent generation.DPE incorporation addresses these issues and significantly improves the short-circuit current density and fill factor.Moreover,non-halogen solvent-processed devices exhibit high hole mobility and low transporting impedance properties.The present study enriches the families of eco-friendly,high-efficiency PSCs fabricated using nonhalogenated solvents. | Yi Chen Xiangxu Ding Ge Wang Songwen Xiao Xin Liu Zihan Zhu Chen Wang Shanpeng Wen | 2022 | Transactions of Tianjin University2022，28，5： | 0 |
