| 1 | Achieving over 16% efficiency for single-junction organic solar cells显示文摘To achieve high photovoltaic performance of bulk hetero-junction organic solar cells(OSCs), a range of critical factors including absorption profiles, energy level alignment, charge carrier mobility and miscibility of donor and acceptor materials should be carefully considered. For electron-donating materials, the deep highest occupied molecular orbital(HOMO) energy level that is beneficial for high open-circuit voltage is much appreciated. However, a new issue in charge transfer emerges when matching such a donor with an acceptor that has a shallower HOMO energy level. More to this point, the chemical strategies used to enhance the absorption coefficient of acceptors may lead to increased molecular crystallinity, and thus result in less controllable phase-separation of photoactive layer. Therefore, to realize balanced photovoltaic parameters, the donor-acceptor combinations should simultaneously address the absorption spectra, energy levels, and film morphologies. Here, we selected two non-fullerene acceptors, namely BTPT-4F and BTPTT-4F, to match with a wide-bandgap polymer donor P2F-EHp consisting of an imidefunctionalized benzotriazole moiety, as these materials presented complementary absorption and well-matched energy levels. By delicately optimizing the blend film morphology, we demonstrated an unprecedented power conversion efficiency of over 16% for the device based on P2F-EHp:BTPTT-4F, suggesting the great promise of materials matching toward high-performance OSCs. | Baobing Fan Difei Zhang Meijing Li Wenkai Zhong Zhaomiyi Zeng Lei Ying Fei Huang Yong Cao | 2019 | Science China Chemistry2019，62，6： | 38 |
| 2 | Editing of Rice Isoamylase Gene ISA1 Provides Insights into Its Function in Starch Formation显示文摘Isoamylase 1(ISA1) is an isoamylase-type debranching enzyme which plays a predominant role in amylopectin synthesis. In this study, the clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated endonuclease 9(CRISPR/Cas9) system was used to edit ISA1 gene in rice via Agrobacterium-mediated transformation. We identified 36 genetic edited lines from 55 T_0 transgenic events, and classified the mutation forms into 7 types. Of those, two homozygous mutants, cr-isa1-1(type 1, with an adenine insertion) and cr-isa1-2(type 3, with a cytosine deletion) were selected for further analysis. Seed sizes of both cr-isa1-1 and cr-isa1-2 were affected, and the two mutants also displayed a shrunken endosperm with significantly lower grain weight. Electron microscopy analysis showed that abnormal starch granules and amyloplasts were found in cr-isa1-1 and cr-isa1-2 endosperm cells. The contents of total starch, amylose and amylopectin in the endosperm of the cr-isa1 mutants were significantly reduced, whereas sugar content and starch gel consistency were observably increased compared to the wild-type. The gelatinization temperature and starch chain length distributions of the cr-isa1 mutants were also altered. Moreover, transcript levels of most starch synthesis-related genes were significantly lower in cr-isa1 mutants. In conclusion, the results indicated that gene edition of ISA1 affected starch synthesis and endosperm development, and brought potential implications for rice quality breeding. | CHAO Shufen CAI Yicong FENG Baobing JIAO Guiai SHENG Zhonghua LUO Ju TANG Shaoqing WANG Jianlong HU Peisong WEI Xiangjin | 2019 | Rice science2019，26，2： | 10 |
| 3 | Side-chain modification of polyethylene glycol on conjugated polymers for ternary blend all-polymer solar cells with efficiency up to 9.27%显示文摘With the rapid progress achieved by all-polymer solar cells(all-PSCs), wide-bandgap copolymers have attracted intensive attention for their unique advantage of constructing complementary absorption profiles with conventional narrow-bandgap copolymers. In this work, we designed and synthesized a wide bandgap ternary copolymer PEG-2% which has the benzodithiophene-alt-difluorobenzotriazole as the backbone and the polyethylene glycol(PEG) modified side chain. The PBTA-PEG-2%:N2200 can be processed with a non-chlorinated solvent of 2-methyl-tetrahydrofuran(MeTHF) for the binary all-PSC, which exhibits a moderate photovoltaic performance. In particular, the ternary all-PSCs that consisting an additional narrow bandgap polymer donor PTB7-Th can also be processed with MeTHF, resulting in an unprecedented power conversion efficiency(PCE)of 9.27%, and a high PCE of 8.05% can be achieved with active layer thickness of 240 nm, both of which are the highest values so far reported from all-PSCs. Detailed investigations revealed that the dramatically improved device performances are attributable to the well-extended absorption band in the photoactive layer. Hence,developing novel copolymers with tailored side chains, and introducing additional polymeric components, can broaden the horizon for high-performance all-PSCs. | Zhenye Li Baobing Fan Baitian He Lei Ying Wenkai Zhong Feng Liu Fei Huang Yong Cao | 2018 | Science China Chemistry2018，61，4： | 4 |
| 4 | Glucose-derived hydrothermal carbons as energy storage booster for vanadium redox flow batteries显示文摘Fabricating of high performance electrodes by a sustainable and cost effective method is essential to the development of vanadium redox flow batteries(VRFBs).In this work,an effective strategy is proposed to deposit carbon nanoparticles on graphite felts by hydrothermal carbonization method.This in-situ method minimizes the drop off and aggregation of carbon nanoparticles during electrochemical testing.Such integration of felts and hydrothermal carbons(HTC)produces a new electrode that combines the outstanding electrical conductivity of felts with the effective redox active sites provided by the HTC coating layer.The presence of the amorphous carbon layers on the felts is found to be able to promote the mass/charge transfer,and create oxygenated/nitrogenated active sites and hence enhances wettability.Consequently,the most optimized electrode based on a rational approach delivers an impressive electrochemical performance toward VRFBs in wide range of current densities from 200 to 500 mAcm^-2.The voltage efficiency(VE)of GFs-HTC is much higher than the VEs of the pristine GFs,especially at high current densities.It exhibits a 4.18 times increase in discharge capacity over the pristine graphite felt respectively,at a high current density of 400 mAcm^-2.The enhanced performance is attributed to the abundant active sites from amorphous hydrothermal carbon,which facilitates the fast electrochemical kinetics of vanadium redox reactions.This work evidences that the glucose-derived hydrothermal carbons as energy storage booster hold great promise in practical VRFBs application. | Jiugen Qiu Baobing Huang Yuchuan Liu Dongyang Chen Zailai Xie | 2020 | Journal of Energy Chemistry2020，29，6： | 2 |
| 5 | Recent progress in thick-film organic photovoltaic devices:Materials,devices,and processing显示文摘A successful transfer of organic photovoltaic technologies from lab to fab has to overcome a range of critical challenges such as developing high-mobility light-harvesting materials,minimizing the upscaling losses,designing advanced solar modules,controlling film quality,decreasing overall cost,and extending long-operation lifetime.To realize large-area devices toward practical applications,much effort has been devoted to understanding the fundamental mechanism of how molecular structures,device architectures,interfacial engineering,and light management and carrier dynamics affect photovoltaic performance.Such studies addressed various fundamental issues of charge carrier behavior in organic heterojunctions primarily in terms of exciton generation dependence upon light incidence,charge transportation dependence on built-in electric field,and charge extraction versus recombination.In consideration of high-throughput roll-to-roll process for large-scale fabrication of organic photovoltaic devices,it is highly appreciable to realize high power conversion efficiencies that are highly tolerable to the film thickness.Herein we summarize the recent progress in developing thick-film organic photovoltaic devices from the perspective of efficiency-loss mechanisms,material design,and device optimization strategies,proposing guidelines for designing high-efficiency thickness-insensitive devices toward mass production. | Difei Zhang Baobing Fan Lei Ying Ning Li Christoph J Brabec Fei Huang Yong Cao | 2021 | SusMat2021，1，1： | 2 |

| 9 | Improving ORR activity of carbon nanotubes by hydrothermal carbon deposition method显示文摘Nitrogen doped carbons are an important family of materials with ideal activity for oxygen reduction reaction(ORR). It is always interesting to search functional carbons with high heteroatom contents and desirable structure for ORR. Within this study, the surface modification of carbon nanotubes(CNTs) via hydrothermal carbonization(HTC) technique in the presence of glucose and urea was reported, where the surface of CNTs is successfully coated by nitrogen containing hydrothermal carbon layers. The resulting composite combines both advantages of the outstanding electrical conductivity of CNTs and the effective ORR active sites provided by doped nitrogen in the HTC carbon layers. By controlling the ratio of glucose and urea, the nitrogen contents coated on the surface of CNTs can reach up to 1.7 wt%. The resulting materials show outstanding electrochemical activity towards ORR in alkaline electrolyte, making it one of the valuable metal-free electrode materials and a competent alternative to the state-of-the-art Pt/C catalyst. | Baobing Huang Lu Peng Fangfang Yang Yuchuan Liu Zailai Xie | 2017 | Journal of Energy Chemistry2017，26，4： | 1 |
| 10 | Approaching 19%efficiency and stable binary polymer solar cells enabled by a solidification strategy of solvent additive显示文摘Additives play a crucial role in enhancing the photovoltaic performance of polymer solar cells(PSCs).However,the typical additives used to optimize blend morphology of PSCs are still high boiling-point solvents,while their trace residues may reduce device stability.Herein,an effective strategy of“solidification of solvent additive(SSA)”has been developed to convert additive from liquid to solid,by introducing a covalent bond into low-cost solvent diphenyl sulfide(DPS)to synthesize solid dibenzothiophene(DBT)in one-step,which achieves optimized morphology thus promoting efficiency and device stability.Owing to the fine planarity and volatilization of DBT,the DBT-processed films achieve ordered molecular crystallinity and suitable phase separation compared to the additive-free or DPS-treated ones.Importantly,the DBT-processed device also possesses improved light absorption,enhanced charge transport,and thus a champion efficiency of 17.9%is achieved in the PM6:Y6-based PSCs with an excellent additive component tolerance,reproducibility,and stability.Additionally,the DBT-processed PM6:L8-BO-based PSCs are further fabricated to study the universality of SSA strategy,offering an impressive efficiency approaching19%as one of the highest values in binary PSCs.In conclusion,this article developed a promising strategy named SSA to boost efficiency and improve stability of PSCs. | Manjun Xiao Longfei Liu Yongdie Meng Baobing Fan Wenyan Su Conggui Jin Luocheng Liao Fan Yi Chao Xu Rui Zhang Alex K.-Y.Jen Wei Ma Qunping Fan | 2023 | Science China Chemistry2023，66，5： | 1 |

| 19 | Tunable ferromagnetic Weyl fermions from a hybrid nodal ring显示文摘Realization of nontrivial band topology in condensed matter systems is of great interest in recent years.Using first-principles calculations and symmetry analysis,we propose an exotic topological phase with tunable ferromagnetic Weyl fermions in a halfmetallic oxide CrP_(2)O_(7).In the absence of spin–orbit coupling(SOC),we reveal that CrP_(2)O_(7) possesses a hybrid nodal ring.When SOC is present,the spin-rotation symmetry is broken.As a result,the hybrid nodal ring shrinks to discrete nodal points and forms different types of Weyl points.The Fermi arcs projected on the(100)surface are clearly visible,which can contribute to the experimental study for the topological properties of CrP_(2)O_(7).In addition,the calculated quasiparticle interference patterns are also highly desirable for the experimental study of CrP_(2)O_(7).Our findings provide a good candidate of ferromagnetic Weyl semimetals,and are expected to realize related topological applications with their attracted features. | Baobing Zheng Bowen Xia Rui Wang Jinzhu Zhao Zhongjia Chen Yujun Zhao Hu Xu | 2019 | npj Computational Materials2019，，1： | 0 |
