| 2 | Progress of all-perovskite tandem solar cells:the role of narrow-bandgap absorbers显示文摘Perovskite solar cells(PSCs)have gained increasing attention due to their excellent photovoltaic performance,achieving certified power conversion efficiency(PCE)of 25.2%.To further enhance PCE and break the Shockley-Queisser limit of the single junction PSCs,great efforts have been made in tandem solar cells based on perovskite,including perovskite/Si,and perovskite/perovskite(all-perovskite).Among them,all-perovskite tandem solar cells exhibit unique advantages of both lowcost fabrication and high efficiency.They have advanced rapidly in these years,due to the realization of stable and efficient narrow-bandgap perovskites.In this work,we review the development of monolithic all-perovskite tandem solar cells and highlight the critical role of narrow-bandgap perovskites in recent progress of all-perovskite solar cells.We also propose our perspective of future directions on this subject. | Xinhui Luo Tianhao Wu Yanbo Wang Xuesong Lin Hongzhen Su Qifeng Han Liyuan Han | 2021 | Science China Chemistry2021，64，2： | 1 |
| 3 | Stable perovskite solar cells with 23.12% efficiency and area over 1 cm^(2) by an all-in-one strategy显示文摘To realize the commercialization of perovskite solar cells(PSCs), it is required to overcome the remaining challenges in device enlargement and operational stability. Here, we report an all-in-one strategy by integrating the oxidation of hole-transport material(HTM) with the formation of the passivation layer, which simultaneously solved the stability issues caused by HTM oxidation and realized the uniform defects in passivation over a large area. The resulting devices achieved a certified PCE of23.12% on average with an aperture area of 1.04 cm^(2) and are reproducible with high operational stability because of the exclusion of air exposure, hygroscopic Li-TFSI, and the lithium-based wastes, maintaining ca. 90% of their initial PCEs after operation at the maximum power point under continuous 1 sun illumination for 1,600 h. Our strategy simplifies the fabrication process of PSCs, which is compatible with commercial-scale methods, offering facile access to efficient and stable large-area PSCs. | Hongzhen Su Xuesong Lin Yanbo Wang Xiao Liu Zhenzhen Qin Qiwei Shi Qifeng Han Yiqiang Zhang Liyuan Han | 2022 | Science China Chemistry2022，65，7： | 0 |
| 4 | EQUIAXED REFINEMENT OF GRAINS IN ALLOY TC11显示文摘The formation reason and elimination method of non-uniform microstructure defects in Ti al-loy TC11 bar have been studied.The coagulating and coarsening into block of the part ofgrain boundary α and secondary α seem to be caused by the ingot cogging and initial forgingtemperature in the β region as well as no more enough deformation and uneven distribution.The grain α,elongated α and blocky α may be finally eliminated by adopting the technique of(α+β)thermomechanical processing+β processing,W.Q.+recrystallization annealing,A.C.,thus the size of uniform and fine equiaxed α structure is believed to be reduced to 1.9258μm. | SU Zuwu MENG Guowen GUO Hongzhen LIU Jianchao YAO Zekun Northwestern Polytechnical University,Xi’an,ChinaYANG Zhaosu HU Zongshi Baoji Non-Ferrous Metals Mill,Baoji,China | 1992 | Acta Metallurgica Sinica(English Letters)1992，5，8： | 0 |
| 5 | An In-Situ Formed Tunneling Layer Enriches the Options of Anode for Efficient and Stable Regular Perovskite Solar Cells显示文摘Perovskite solar cells(PSCs)are taking steps to commercialization.However,the halogen-reactive anode with high cost becomes a stumbling block.Here,the halogen migration in PSCs is utilized to in situ generate a uniform tunneling layer between the hole transport materials and anodes,which enriches the options of anodes by breaking the Schottky barrier,enabling the regular PSCs with both high efficiency and stability.Specifically,the regular PSC that uses silver iodide as the tunneling layer and copper as the anode obtains a champion power conversion efficiency of 23.24%(certified 22.74%)with an aperture area of 1.04 cm^(2).The devices are stable,maintaining 98.6%of the initial effi-ciency after 500 h of operation at the maximum power point with continuous 1 sun illumination.PSCs with different tunneling layers and anodes are fabricated,which confirm the generality of the strategy. | Xuesong Lin Yanbo Wang Hongzhen Su Zhenzhen Qin Ziyang Zhang Mengjiong Chen Min Yang Yan Zhao Xiao Liu Xiangqian Shen Liyuan Han | 2023 | Nano-Micro Letters2023，15，1： | 0 |
| 6 | Numerical studies of stepwise radial fuel shuffling in a traveling wave reactor显示文摘The concept of travelling wave reactor(TWR)applies the mechanism of self-sustaining and propagating nuclear fission travelling waves in fertile media of 238U and 232Th to achieve very high fuel utilization.Based on this concept,a stepwise radial fuel shuffling strategy was proposed and applied to a sodium-cooled fast reactor(SFR)loading metallic 238U fuel.The multi-group deterministic neutronic code ERANOS with JEFF3.1 data library was used as a basic tool to perform the neutronics and burnup calculations.The inward fuel shuffling calculations were first performed in a 1-D cylindrical case for parametric understanding,and then extended to a 2-D R-Z case.The shuffling calculations for the 1-D and 2-D SFR model yielded some interesting results.The asymptotic keff varied parabolically with the characteristic fluence,while the burnup increased linearly.The highest burnup achieved in 2-D case was 38%.The power peak shifted from the fuel outlet side(core centre)to the fuel inlet side(core periphery)in both 1-D and 2-D cases and the corresponding peaking factor decreased dramatically along with the characteristic fluence.The present research demonstrated that the proposed stepwise radial fuel shuffling in the sodium fast reactor achieved the characteristics of the traveling wave reactor. | ZHANG DaLin ZHENG MeiYin AN HongZhen CHEN XueNong TIAN WenXi QIU SuiZheng SU GuangHui | 2014 | Science China(Technological Sciences)2014，57，6： | 0 |
| 7 | Self-assembly of Micrometer-long DNA Nanoribbons with Four Oligonucleotides显示文摘DNA nanostructures have found widespread applications in areas including nanoelectronics and biomedicine.However,traditional DNA origami needs a long single-stranded virus DNA and hundreds of short DNA strands,which make this method complicated and money-consuming.Here,we present a protocol for the assembly of DNA nanoribbons with only four oligonucleotides.DNA nanoribbons with different dimensions were successfully assembled with a 96-base scafford strand and three short staples.These biotinylated nanoribbons could also be decorated with streptavidins.This approach suggests that there exist great design spaces for the creation of simple nucleic acid nanostructures which could facilitate their application in plasmonic or drug delivery. | Jie Chao Xiangyuan Ouyang Hongzhen Peng Shao Su Lianhui Wang | 2015 | Chinese Journal of Chemistry2015，33，5： | 0 |
| 8 | Identification of the hydrogen utilization pathway for the electrocatalytic hydrogenation of phenol显示文摘Electrochemical hydrogenation(ECH)of biomass-derived platform molecules is a burgeoning route for the sustainable utilization of hydrogen.However,the noble-metal-catalyzed ECH of phenolic compounds suffers from intense competition with hydrogen evolution reaction.We prepared Pt Rh bimetallic nanoparticles dispersed on highly ordered mesoporous carbon nanospheres,which improves the utilization efficiency of adsorbed hydrogen(H_(ad))to ECH in H-UPD region(>0 V vs.RHE).Further analysis reveals(i)the strong overlapping between the d-orbitals of Pt and Rh enhances specific adsorption of phenol;(ii)incorporation of Rh devotes an electronic effect on weakening the alloy-H_(ad)interaction to increase the FE of ECH.DFT calculations confirm the selectivity difference and the ECH parallel pathways:cyclohexanol and cyclohexanone are formed via hydrogenation/dehydrogenation of the intermediate ^(*)C_(6)H_(10) OH.These findings deepen our fundamental understanding of the ECH process,and cast new light on exploration of highly efficient electrocatalysts for biomass upgrading. | Ling Zhou Xiaorong Zhu Hui Su Hongzhen Lin Yanhong Lyu Xu Zhao Chen Chen Nana Zhang Chao Xie Yingying Li Yuxuan Lu Jianyun Zheng Benrt Johannessen San Ping Jiang Qinghua Liu Yafei Li Yuqin Zou Shuangyin Wang | 2021 | Science China Chemistry2021，64，9： | 0 |
