| 1 | Reducing Energy Loss and Morphology Optimization Manipulated by Molecular Geometry Engineering for Hetero-junction Organic Solar Cells显示文摘of main observation and conclusion Molecular geometry engineering is an efective strategy to control the micromorphology and molecularenergy level in organic photovoltaics(OPVs).Two novel copolymers based on alkysilyl-and chloride-functionalied benzodithiophene(BDT)were designed and synthesized for wide bandgap copolymer donor materials in OPVs.It was found that the two copolymers exhited distinctly different proper-ties in active layer when blended with fulerene-fre acceptor T-4.The chloride-functionalited copolymer PBDTCI-TZ2 with deeper molecular energy leveland better coplanar structure induced more ordered aggregation in blend flm.Thus,the device based on PBDTC-TZ exhibits better energy alinmentwith IT-4F and smallr radiative recombination.furthermore,the non-radiative recombination of PBDTCI-TZ.T-4F based device is about 45 mV lowerthan the PBDTS-TZ/T-4F based device,contributing to a lower enery loss(Ein,and a higher open-cicut voltage(Vc).As a resut,the devices based onthe blend of PBDTC-TZ2.IT-4F exhibit a high power conversion efficiency(PCE)of up to 12.2%with a high Vvoe of 0.837 Vv,higher than that of PBDTSi-TZ:IT-4F,of which the PCE is 11.2%with a Voc of 0.781V. | Guodong Xu Huan Rao Xunfan Liao Youdi Zhang Yuming Wang Zhi Xing Ting Hu Licheng Tan Lie Chen Yiwang Chen | 2020 | Chinese Journal of Chemistry2020，38，12： | 4 |
| 2 | Wide Band-gap Two-dimension Conjugated Polymer Donors with Different Amounts of Chlorine Substitution on Alkoxyphenyl Conjugated Side Chains for Non-fullerene Polymer Solar Cells显示文摘In this study,wide bandgap(WBG)two-dimensional(2D)copolymer donors(DZ1,DZ2,and DZ3)based on benzodithiophene(BDT)on alkoxyphenyl conjugated side chains without and with different amounts of chlorine atoms and difluorobenzotriazole(FBTZ)are designed and synthesized successfully for efficient non-fullerene polymer solar cells(PSCs).Three polymer donors DZ1,DZ2,and DZ3 display similar absorption spectra at 300-700 nm range with optional band-gap(Egopt)of 1.84,1.92,and 1.97 eV,respectively.Compared with reported DZ1 without chlorine substitution,it is found that introducing chlorine atoms into the meta-position of the alkoxyphenyl group affords polymer possessing a deeper the highest occupied molecular orbital(HOMO)energy level,which can increase open circuit voltage(Voc)of PSCs,as well as improve hole mobility.Non-fullerene bulk heterojunction PSCs based on DZ2:MelC demonstrate a relatively high power conversion efficiency(PCE)of 10.22%with a Voc of 0.88 V,a short-circuit current density(Jsc)of 17.62 mA/cm^2,and a fill factor(FF)of 68%,compared with PSCs based on DZ1:MelC(a PCE of 8.26%)and DZ3:MelC(a PCE of 6.28%).The results imply that adjusting chlorine atom amount on alkoxyphenyl side chains based on BDT polymer donors is a promising approach of synthesizing electron-rich building block for high performance of PSCs. | Youdi Zhang Yong Wang Ruijie Ma Zhenghui Luo Tao Liu So-Huei Kang He Yan Zhongyi Yuan Changduk Yang Yiwang Chen | 2020 | Chinese Journal of Polymer Science2020，38，8： | 3 |
| 3 | Ethylenediamine promoted the hydrogenative coupling of nitroarenes over Ni/C catalyst显示文摘Azobenzene and its derivatives are key raw materials and it is an environmentally friendly method for the preparation of azobenzene by hydrogenative coupling of nitrobenzene. The development of nickel based catalyst for organic transformations is of importance because of its relatively low cost and toxicity. In this work, we found that ethylenediamine can enrich the electron state of Ni and make the azobenzene easily desorb from the surface of the catalyst, which inhibits the hydrogenation of azobenzene to aniline. The selectivity of azobenzene is greatly improved. When the ratio of Ni and ethylenediamine is 1:10, the yield of the azobenzene can reach 95.5%. | Youdi Yang Shaopeng Li Chao Xie Hangyu Liu Yanyan Wang Qingqing Mei Huizhen Liu Buxing Han | 2019 | Chinese Chemical Letters2019，30，1： | 3 |

| 5 | Additive-free non-fullerene organic solar cells with random copolymers as donors over 9% power conversion efficiency显示文摘In this study, a series of random conjugated polymers (PBDB-TBTn) as donors were designed and synthesized. In these polymers, benzodithiophene unit with thiophene conjugated side chains (BDT) are donor part, and two different content of benzo[1,2-c:4,5-c']dithiophene-4,8-dione (BDD) and difluorobenzothiadizole (BT) linked alkylthiophene are acceptor unit. Polymer solar cells (PSCs) were fabricated with ITIC as an acceptor, and over the power conversion efficiency (PCE) of 9%was obtained, with open circuit voltage (Voc) of 0.86 V, short-circuit current density (Jsc) of 16.84 mA/cm^2, and fill factor (FF) of 62.5%. These random conjugated polymers based solar cells are insensitive to solvent additives and thermal annealing. The performance of the device decreases gradually with the increasing of the proportion of fluorinated acceptor unit. The declining efficiency is due to the excessive fluorinated acceptor unit, which leads to over aggregated topography, destroys the effective charge transport pathways, and affects phase separation domain size between the donor and the acceptor. The phenomena are explained by the charge carrier recombination, atomic force microscope (AFM), and transmission electron microscope (TEM). These results indicate that proper addition of fluorinated acceptor units to build random copolymers can enhance the efficiency of organic photovoltaics toward additive-free and thermal annealing-free PSCs. | Meimei Wu Laitao Shi Yu Hu Lie Chen Ting Hu Youdi Zhang Zhongyi Yuan Yiwang Chen | 2019 | Chinese Chemical Letters2019，30，6： | 3 |
| 6 | Morphology-Controlled Synthesis of CeO_2 Microstructures and Their Room Temperature Ferromagnetism显示文摘Gear-shape CeO_2 microstructures have been synthesized via a facile hydrothermal method with Ce(NO_3)_3·6H_2O as the cerium source, NH_4HCO_3 as both the precipitator and the carbon source, and cetyltrimethyl ammonium bromide(CTAB) as the surfactant. X-ray diffraction(XRD) inferred that the synthesized CeO_2 microstructures exhibited a fluorite structure. The band gap(Eg) of CeO_2 samples is larger than that of bulk. X-ray photoelectron spectroscopy(XPS) showed that there are plenty of Ce^(3+) ions and oxygen vacancies at the surface of CeO_2 samples. All the synthesized CeO_2 samples exhibited the room temperature ferromagnetism, and the saturation magnetization increases with the increases of lattice parameter and Eg. The room temperature ferromagnetism mechanism of gear-shape CeO_2 is mainly attributed to the influence Ce^(3+) ions. | Fanming Meng Zhenghua Fan Cheng Zhang Youdi Hu Tao Guan Aixia Li | 2017 | Journal of Materials Science & Technology2017，33，5： | 2 |

| 8 | Highly crystalline acceptor materials based on benzodithiophene with different amount of fluorine substitution on alkoxyphenyl conjugated side chains for organic photovoltaics显示文摘Organic solar cells based on narrow bandgap small-molecule acceptors(SMAs)with highly crystalline characteristics have attracted great attentions for their superiority in obtaining high photovoltaic efficiency.Employing highly crystalline SMAs to enhance power conversion efficiencies(PCEs)by regulating and controlling morphology and compatibility of donor and acceptor materials has turned out to be an effective approach.In this study,we synthesized three different crystalline SMAs by using fluorine substitution on alkoxyphenyl conjugated side chains to modulate the relationship of crystallinity and morphologies,namely ZY1(zero F atoms),ZY2(two F atoms),and ZY3(four F atoms).The three SMAs show the broad absorption edges and similar frontier orbital energy levels,generating the analogical(over 0.9 V)open circuit voltage(VOC)of the polymer solar cells(PSCs).As a result,the PM6:ZY2-based PSCs yield a PCE of 10.81%with a VOC of 0.95 V,a short-circuit current density(JSC)of 16.154 mA cm^(-2),and a fill factor(FF)of 0.71,which is higher than that of 9.17%(PM6:ZY1)and 6.37%(PM6:ZY3).And the PCE(17.23%)of the PM6:Y6:ZY2 based ternary PSCs is also higher than that of 16.32%PM6:Y6 based binary device.Obviously,the results demonstrate that adding fluorine atoms on the conjugated side chains to construct high crystalline materials is a positive strategy to effectively increase the efficiencies of binary and ternary PSCs. | Youdi Zhang Ruijie Ma Yong Wang Ying Wang Tao Liu Yiqun Xiao Yongjoon Cho Zhenghui Luo Xinhui Lu Lun Zhao Zhongyi Yuan Changduk Yang He Yan Yiwang Chen | 2021 | Materials Reports(Energy)2021，1，4： | 1 |

| 15 | Analysis of cooperation equilibrium of participants in power battery recycling chains considering information barrier显示文摘In the era of large-scale retirement of power batteries,there are information barriers and high recovery costs in their recycling.In view of this,in this study we constructed a tripartite evolutionary game model of the cooperation between power battery production and recycling enterprises and government participation.We analyzed the strategic choice of the three parties in the process of power battery recycling and simulated the influence of participants'willingness and information barriers on the strategic choices of the parties.The results showed that power battery production and recycling enterprises,and the government are affected by each other's willingness to participate at different degrees.The willingness of power battery manufacturers and recycling enterprises to cooperate with each other decreased with increases in information barriers.By analyzing the impact of information barrier on power battery recycling,some suggestions are put forward to provide decision-making reference for promoting the sustainable development of power battery industry. | Yanhong Gao Youdi Liu Zhixiong Tan Zhendong Li | 2022 | Chinese Journal of Population,Resources and Environment2022，20，2： | 0 |

| 17 | Crystal-phase engineering of PdCu nanoalloys facilitates selective hydrodeoxygenation at room temperature显示文摘Selective hydrodeoxygenation of biomass-derived aromatic alcohols to value-added chemical or fuel is of great importance for sustainable biomass upgrading,and hydrodeoxygenation of 5-hydroxymethylfurfural(HMF)to 2,5-dimethylfuran(DMF)is one of the most attractive reactions.Achieving the conversion of HMF to DMF using H_(2)at ambient temperature is challenging.In this work,we used PdCu nanoalloys to catalyze the selective hydrodeoxygenation reaction of HMF to DMF using H_(2)as the reducing agent.The reaction path and the product selectivity are governed by the crystallographic phase of the PdCu nanoalloys.It was discovered that body-centered cubic(BCC)PdCu nanoalloys supported on activated carbon(AC)exhibited outstanding performance with 93.6%yield of DMF at room temperature(PdCu/AC-BCC).A combination of experimental and density functional theory(DFT)studies showed that the tilted adsorption modes of furanic intermediates on PdCu-BCC nanoalloy surfaces accounted for the high selectivity of DMF;however,furan ring was activated on PdCu face-centered cubic(FCC)nanoalloy surfaces.Furthermore,PdCu/AC-BCC could also catalyze the hydrodeoxygenation of other aromatic alcohols at room temperature while maintaining the aromatic structures.This work opens the way for selective hydrodeoxygenation of the aromatic alcohols at room temperature with the aromatic ring intact. | Shaopeng Li Minghua Dong Mi Peng Qingqing Mei Yanyan Wang Junjuan Yang Youdi Yang Bingfeng Chen Shulin Liu Dequan Xiao Huizhen Liu Ding Ma Buxing Han | 2022 | The Innovation2022，3，1： | 0 |

| 20 | The effects of Eu^(3+) doping on the epitaxial growth and photovoltaic properties of BiFeO_(3) thin films显示文摘Nowadays,photovoltaic effect has been widely studied in various ferroelectric materials due to its ap-plications as optoelectronic devices.In this work,with BiFeO_(3)(BFO)films as the photovoltaic materials,we report the effects of Eu^(3+)doping content on the phase structure,ferroelectric and optical properties of BFO films grown on Ca_(0.96) Ce_(0.04) MnO_(3)/YAlO_(3)(001)substrate.We found that a small doping level of 0.05 could induce a phase change of BFO from tetragonal to rhombohedral,due to the shrinking of the lattice upon Eu^(3+)doping and the breaking of surface terrace structure induced by Ca_(0.96) Ce_(0.04) MnO_(3) layer.This results in a sharp band gap reduction from 3.30 eV to 2.60 eV,and a decrease in the coercivity of ferroelectric polarization switching.Based on these findings,we investigate the photovoltaic effects of ITO/Eu_(x) Bi_(1-x) FeO_(3)/Ca_(0.96) Ce_(0.04) MnO_(3) vertical capacitors.It is found that the short-circuit current density(J_(sc))decreases with increasing Eu^(3+)doping,whereas the open-circuit voltage(V_(oc))first increases to a level of 0.1 V and then decreases with further Eu^(3+)doping.This could be explained by the combined ef-fect of Schottky-junction and depolarization field on the photovoltaic process.Our research suggests that a moderate Eu^(3+)doping is helpful for enhancing the photovoltaic effect of BFO thin film devices. | Dingshuai Feng Biaohong Huang Lingli Li Xiaoqi Li Youdi Gu Weijin Hu Zhidong Zhang | 2022 | Journal of Materials Science & Technology2022，，11： | 0 |
