| 1 | Enhanced power conversion efficiency in iridium complexbased terpolymers for polymer solar cells显示文摘By introducing various low concentrations of Iridium complexes to the famous donor polymer of PTB7-Th backbone,new heavy metal containing terpolymers have been demonstrated.When blended with PC71BM,an obvious increase of power conversion efficiency(PCE)is obtained in 1 mol%Ir containing polymer for different photovoltaic devices either using Ca or PDIN as cathode interface layers.The impact of molecular weight on the photovoltaic performance has been particularly considered by using three batches of control polymer PTB7-Th to ensure a fair and more convincing comparison.At similar molecular weight conditions(Mn:~60 kg mol−1,M_(w):100-110 kg mol^(−1)),the 1 mol%Ir containing PTB7-ThIr1/PC71BM blends exhibits enhanced PCE to 9.19%compared with 7.92%of the control PTB7-Th.Through a combination of physical measurement,such as optoelectrical characterization,GIWAXS and pico-second time-resolved photoluminescence,the enhancement are contributed from comprehensive factors of higher hole mobility,less bimolecular recombination and more efficient slow process of charge separation. | Zhongyuan Xue Shifan Wang Jie Yang Yu Zhong Min Qian Cheng Li Zhiguo Zhang Guichuan Xing Sven Huettner Youtian Tao Yongfang Li Wei Huang | 2018 | npj Flexible Electronics2018，2，1： | 1 |
| 2 | Valence electronic engineering of superhydrophilic Dy-evoked Ni-MOF outperforming RuO_(2) for highly efficient electrocatalytic oxygen evolution显示文摘Tackling the problem of poor conductivity and catalytic stability of pristine metal-organic frameworks(MOFs) is crucial to improve their oxygen evolution reaction(OER) performance.Herein,we introduce a novel strategy of dysprosium(Dy) doping,using the unique 4f orbitals of this rare earth element to enhance electrocatalytic activity of MOFs.Our method involves constructing Dy-doped Ni-MOF(Dy@Ni-MOF) nanoneedles on carbon cloth via a Dy-induced valence electronic perturbation approach.Experiments and density functional theory(DFT) calculations reveal that Dy doping can effectively modify the electronic structure of the Ni active centers and foster a strong electronic interaction between Ni and Dy.The resulting benefits include a reduced work function and a closer proximity of the d-band center to the Fermi level,which is conducive to improving electrical conductivity and promoting the adsorption of oxygen-containing intermediates.Furthermore,the Dy@Ni-MOF achieves superhydrophilicity,ensuring effective electrolyte contact and thus accelerating reaction kinetics,Ex-situ and in-situ analysis results manifest Dy_(2)O_(3)/NiOOH as the actual active species.Therefore,Dy@Ni-MOF shows impressive OER performance,significantly surpassing Ni-MOF.Besides,the overall water splitting device with Dy@NiMOF as an anode delivers a low cell voltage of 1.51 V at 10 mA cm^(-2) and demonstrates long-term stability for 100 h,positioning it as a promising substitute for precious metal catalysts. | Zhiyang Huang Miao Liao Shifan Zhang Lixia Wang Mingcheng Gao Zuyang Luo Tayirjan Taylor Isimjan Bao Wang Xiulin Yang | 2024 | Journal of Energy Chemistry2024，90，3： | 0 |
| 3 | The Tianlai Cylinder Pathfinder array: System functions and basic performance analysis显示文摘The Tianlai Cylinder Pathfinder is a radio interferometer array designed to test techniques for 21 cm intensity mapping in the post-reionization Universe,with the ultimate aim of mapping the large scale structure and measuring cosmological parameters such as the dark energy equation of state.Each of its three parallel cylinder reflectors is oriented in the north-south direction,and the array has a large field of view.As the Earth rotates,the northern sky is observed by drift scanning.The array is located in Hongliuxia,a radio-quiet site in Xinjiang,and saw its first light in September 2016.In this first data analysis paper for the Tianlai cylinder array,we discuss the sub-system qualification tests,and present basic system performance obtained from preliminary analysis of the commissioning observations during 2016-2018.We show typical interferometric visibility data,from which we derive the actual beam profile in the east-west direction and the frequency band-pass response.We describe also the calibration process to determine the complex gains for the array elements,either using bright astronomical point sources,or an artificial on site calibrator source,and discuss the instrument response stability,crucial for transit interferometry.Based on this analysis,we find a system temperature of about 90 K,and we also estimate the sensitivity of the array. | JiXia Li ShiFan Zuo FengQuan Wu YouGang Wang JuYong Zhang ShiJie Sun YiDong Xu ZiJie Yu Reza Ansari YiChao Li Albert Stebbins Peter Timbie YanPing Cong JingChao Geng Jie Hao QiZhi Huang JianBin Li Rui Li DongHao Liu YingFeng Liu Tao Liu John PMarriner ChenHui Niu Ue-Li Pen Jeffery BPeterson HuLi Shi Lin Shu YaFang Song HaiJun Tian GuiSong Wang QunXiong Wang RongLi Wang WeiXia Wang Xin Wang KaiFeng Yu Jiao Zhang BoQin Zhu JiaLu Zhu XueLei Chen | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，12： | 0 |
| 4 | Experimental and theoretical analysis of a hybrid vibration energy harvester with integrated piezoelectric and electromagnetic interaction显示文摘Harvesting vibration energy has attracted the attention of researchers in recent decades as a promising approach for powering wireless sensor networks.The hybridization of piezoelectricity and electromagnetism has proven helpful in the improvement of vibration energy harvesting.In this study,we explore the integration of piezoelectric and electromagnetic parts in one vibration energy harvesting device.Lumped-parameter models of the system are derived considering the different connection topologies of the piezoelectric and electromagnetic parts.Numerical predictions from these models are compared with experimental results to throw light on the nonlinearities in the system.Modifications of the system are also explored to provide insights into opportunities to improve its performance and that of future vibration energy harvesters. | Shifan HUANG Weihao LUO Zongming ZHU Zhenlong XU Ban WANG Maoying ZHOU Huawei QIN | 2023 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2023，24，11： | 0 |
