| 1 | Organic photovoltaic cell with 17% efficiency and superior processability显示文摘The development of organic photoactive materials,especially the newly emerging non-fullerene electron acceptors(NFAs),has enabled rapid progress in organic photovoltaic(OPV)cells in recent years.Although the power conversion efficiencies(PCEs)of the top-performance OPV cells have surpassed 16%,the devices are usually fabricated via a spin-coating method and are not suitable for large-area production.Here,we demonstrate that the fine-modification of the flexible side chains of NFAs can yield 17%PCE for OPV cells.More crucially,as the optimal NFA has a suitable solubility and thus a desirable morphology,the high efficiencies of spin-coated devices can be maintained when using scalable blade-coating processing technology.Our results suggest that optimization of the chemical structures of the OPV materials can improve device performance.This has great significance in larger-area production technologies that provide important scientific insights for the commercialization of OPV cells. | Yong Cui Huifeng Yao Ling Hong Tao Zhang Yabing Tang Baojun Lin Kaihu Xian Bowei Gao Cunbin An Pengqing Bi Wei Ma Jianhui Hou | 2020 | National Science Review2020，7，7： | 7 |
| 2 | 2D materials for conducting holes from grain boundaries in perovskite solar cells显示文摘Grain boundaries in organic-inorganic halide perovskite solar cells(PSCs)have been found to be detrimental to the photovoltaic performance of devices.Here,we develop a unique approach to overcome this problem by modifying the edges of perovskite grain boundaries with flakes of high-mobility two-dimensional(2D)materials via a convenient solution process.A synergistic effect between the 2D flakes and perovskite grain boundaries is observed for the first time,which can significantly enhance the performance of PSCs.We find that the 2D flakes can conduct holes from the grain boundaries to the hole transport layers in PSCs,thereby making hole channels in the grain boundaries of the devices.Hence,2D flakes with high carrier mobilities and short distances to grain boundaries can induce a more pronounced performance enhancement of the devices.This work presents a cost-effective strategy for improving the performance of PSCs by using high-mobility 2D materials. | Peng You Guanqi Tang Jiupeng Cao Dong Shen Tsz-Wai Ng Zafer Hawash Naixiang Wang Chun-Ki Liu Wei Lu Qidong Tai Yabing Qi Chun-Sing Lee Feng Yan | 2021 | Light(Science & Applications)2021，10，4： | 3 |
| 3 | The Main Progress of Perovskite Solar Cells in 2020-2021显示文摘Perovskite solar cells(PSCs)emerging as a promising photovoltaic technology with high efficiency and low manufacturing cost have attracted the attention from all over the world.Both the efficiency and stability of PSCs have increased steadily in recent years,and the research on reducing lead leakage and developing eco-friendly lead-free perovskites pushes forward the commercialization of PSCs step by step.This review summarizes the main progress of PSCs in 2020 and 2021 from the aspects of efficiency,stability,perovskite-based tandem devices,and lead-free PSCs.Moreover,a brief discussion on the development of PSC modules and its challenges toward practical application is provided. | Tianhao Wu Zhenzhen Qin Yanbo Wang Yongzhen Wu Wei Chen Shufang Zhang Molang Cai Songyuan Dai Jing Zhang Jian Liu Zhongmin Zhou Xiao Liu Hiroshi Segawa Hairen Tan Qunwei Tang Junfeng Fang Yaowen Li Liming Ding Zhijun Ning Yabing Qi Yiqiang Zhang Liyuan Han | 2021 | Nano-Micro Letters2021，13，10： | 2 |
| 4 | Advances in studies on hepatic stem cells显示文摘The question whether hepatic stem cells exist or not has been debated for several decades. Current researches confirm that there are hepatic stem cells in the liver. Oval cells, putative bipotential hepatic stem cells, are probably located within canals of Hering, portal tracts or branches of biliary trees. Bone marrow is a potential source of oval cells, indicating that there exists a close relationship between liver and hematopoiesis in adulthood. Hepatic stem cells are able to proliferate in vitro and can be induced to differentiate into hepatocytes. This will provide a promising approach of cell transplantation, tissue engineering and gene therapy for liver diseases. In this review, the evidence of their presence, origin, identification, proliferation in vitro, differentiation by induction, application prospects of hepatic stem cells and future directions for the field are discussed. | HE Zuping, TANG Yuefeng, LIU Yabing and FENG Meifu(State Key Laboratory of Biomembrane and Membrane Biotechnology, Institute of Zoology, Chinese Academy of Sciences, Beijing 100080, China) | 2003 | Progress in Natural Science:Materials International2003，13，3： | 2 |

| 6 | Immunoinhibitory effect of soluble HLA-G1 on the cytotoxicity of NK92 cells显示文摘HLA-G (human leukocyte antigen-G) is a non-classical HLA class I molecule, playing an important immuno-modulatory role in maintaining maternal immune tolerance of the semiallogenic fetus and organ transplantation. In this study, the cDNA sequence of extracellular domain of HLA-G1 was subcloned into the pET28a vector and a soluble 35 kD fusion protein (His-sHLA-G1) with six histine residues was obtained. In the 4 h 51Cr-release assay the fusion protein obviously inhibited the cytotoxicity of NK92 cells in a dose-dependent manner. These results indicated that sHLA-G1, as an activated immunoinhibitor, may provide an effective approach to overcoming the immune rejection of transplantation. | TIAN Xinghui, LI Zhiwei, LIU Yabing, WANG Yun, TANG Haiyang and FENG Meifu(The National Key Laboratory of Biomembrane and Membrane Biotechnology, Institute of Zoology, Chinese Academy of Sciences, Beijing 100080, China) | 2003 | Progress in Natural Science:Materials International2003，13，3： | 1 |

| 11 | Comparative study of the stoichiometric characteristics of karst and non-karst forests in Guizhou, China显示文摘Carbon (C), nitrogen (N), and phosphorous (P) levels and their stoichiometry in plant components (leaves, branch trunks, roots) of trees in a karst forest and non-karst forest are compared. The results show that the C contents, C:N and C:P ratios of dominant species in the karst forest were lower than those in the non-karst forest, but the N and P and the N:P ratio were higher;C:N:P ratios in plant organs of trees in the karst forest were in the order of trunks>roots>branches>leaves. However, C:N:P ratio in the non-karst forest trees were trunks>branches>roots>leaves. Moreover, ratio of C:N:P in trunks was highest and lowest in leaves in both forests. In non-karst forest trees, N:P was in the order of leaves> roots>branches>trunks. There were no significant differences in the ratio of N:P in different plant components of trees in the karst forest. However, in karst and non-karst forest trees, the ratio of N:P in leaves was highest;positive correlations between N and P contents, and N and N:P ratios were observed in both karst and non-karst forests (p<0.001). Negative correlations between P and N:P ratios (p<0.05) were observed in karst forest trees, while positive correlations were observed in non-karst forest trees. | Yabing Zhang Chuanyan Zhou Wenqiang Lv Lihua Dai Jingang Tang Shaoqi Zhou Lihua Huang Anding Li Jianli Zhang | 2019 | Journal of Forestry Research2019，30，3： | 1 |

| 19 | A new perspective to develop regiorandom polymer acceptors with high active layer ductility,excellent device stability,and high efficiency approaching 17%显示文摘The recently reported efficient polymerized small-molecule acceptors(PSMAs)usually adopt a regioregular backbone by polymerizing small-molecule acceptors precursors with a low-reactivity 5-brominated 3-(dicyanomethylidene)indan-1-one(IC)end group or its derivatives,leading to low molecular weight,and thus reduce active layer mechanical properties.Herein,a series of newly designed chlorinated PSMAs originating from isomeric IC end groups are developed by adjusting chlorinated positions and copolymerized sites on end groups to achieve high molecular weight,favorable intermolecular interaction,and improved physicochemical properties.Compared with regioregular PY2Se-Cl-o and PY2Se-Cl-m,regiorandom PY2Se-Cl-ran has a similar absorption profile,moderate lowest unoccupied molecular orbital level,and favorable intermolecular packing and crystallization properties.Moreover,the binary PM6:PY2Se-Cl-ran blend achieves better ductility with a crack-onset strain of 17.5% and improved power conversion efficiency(PCE)of 16.23% in all-polymer solar cells(all-PSCs)due to the higher molecular weight of PY2Se-Cl-ran and optimized blend morphology,while the ternary PM6:J71:PY2Se-Cl-ran blend offers an impressive PCE approaching 17% and excellent device stability,which are all crucial for potential practical applications of all-PSCs in wearable electronics.To date,the efficiency of 16.86% is the highest value reported for the regiorandom PSMAs-based all-PSCs and is also one of the best values reported for the all-PSCs.Our work provides a new perspective to develop efficient all-PSCs,with all high active layer ductility,impressive PCE,and excellent device stability,towards practical applications. | Qunping Fan Ruijie Ma Wenyan Su Qinglian Zhu Zhenghui Luo Kai Chen Yabing Tang Francis RLin Yuxiang Li He Yan Chuluo Yang Alex K.-Y.Jen Wei Ma | 2023 | Carbon Energy2023，5，2： | 0 |
| 20 | Influences of various space current systems on the geomagnetic field in near-Earth space显示文摘Ground and space-based observations of the geomagnetic field are usually a superposition of different sources from the Earth’s core,lithosphere,ocean,ionosphere,and magnetosphere,and also from field-aligned currents coupling the ionosphere and magnetosphere—the meridional currents that connect the two hemispheres and the induced currents due to the variations of fields over time.The fluctuation of magnetic fields generated by these highly dynamic space currents greatly limits the accuracy of the geomagnetic models.In order to better accomplish the scientific objectives of Macao Science Satellite-1(MSS-1),and to improve existing geomagnetic field models,we present here for the first time a self-consistent coupling of solar wind,magnetosphere,and ionosphere,which represents the most developed numerical simulation method for space physics research so far,making it possible to quantify the contribution of different current systems to the total observed magnetic field(B).The results show that numerical simulation can capture main magnetic disturbance characteristics with significant precision.Partial ring current is a major contributor to the latitudinal magnetic perturbation near the equator.Magnetopause and magnetotail currents affect the radial magnetic perturbation around the mid-latitudes.Field-aligned and Pedersen currents produce significant longitudinal and latitudinal magnetic perturbations at high latitudes. | YaBing Wang Yi Zhang YuJie Wang PengFei Liu JianXia Cheng XiZhi Li Kai Tang LiGang Li XiaoWen Duan | 2023 | Earth and Planetary Physics2023，7，1： | 0 |
