| 1 | BRIF and CARIF progress显示文摘China Institute of Atomic Energy (CIAE) is currently constructing Beijing rare ion beam facility (BRIF) and is proposing China advanced rare ion beam facility (CARIF). This paper is aiming at introducing the progress of BRIF project and the con ceptual design CARIF. The ISOL type facility BRIF under construction is composed of a 100 MeV 300 ?A proton cyclotron, an ISOL with mass resolution of 20000, and a super-conducting LINAC of 2 MeV/q, and will be commissioned in 2013. CARIF facility proposed is planned to use both ISOL and PF techniques. It is based on a China advanced research reactor CARR that was critical, with ISOL separation of fission fragment, post acceleration to 150 MeV/u, and fragmentation of neu tron-rich fission fragment beam like 132Sn. Such unique combination will allow CARIF to deliver beam intensity better than the best world facilities by more than one order of magnitude. | LIU WeiPing, LI ZhiHong, BAI XiXiang, WANG YouBao, GUO Bing, PENG ChaoHua, YANG Yi, SU Jun, CUI BaoQun, ZHOU ShuHua, ZHU ShengYun, XIA HaiHong, GUAN XiaLing, ZENG Sheng, ZHANG HuanQiao, CHEN YongShou, TANG HongQing, HUANG Li & FENG BeiYuan China Institute of Atomic Energy, P.

| 2 | Rationally pairing photoactive materials for high-performance polymer solar cells with efficiency of 16.53%显示文摘The emergence of non-fullerene acceptors(NFA) offers a promising opportunity to develop high-performance donor/acceptor pairs with high power conversion efficiency,as NFAs offer tunable energy levels,broad absorption and suitable aggregation property.In order to enhance light-harvesting capability of active layers,we choose a wide bandgap polymer PTQ10 as the donor to blend with a narrow bandgap NFAY6 as the acceptor.In comparison with PTQ10:IDIC blend,~130 nm red-shifted absorption spectrum is observed in the PTQ10:Y6 blend,which potentially enhance the short-circuit current density(Jsc) for the PSCs.In addition,the optimal PTQ10:Y6 blend shows higher photoluminescence quenching efficiency and more efficient charge separation,higher charge mobilities,as well as weaker bimolecular recombination over the PTQ10:IDIC blend,which leads to an outstanding power conversion efficiency(PCE) of 16.53%,with a notable Jsc of 26.65 mA cm^-2 and fill factor(FF) of 0.751. | Yue Wu Yan Zheng Hang Yang Chenkai Sun Yingying Dong Chaohua Cui He Yan Yongfang Li | 2020 | Science China Chemistry2020，63，2： | 5 |
| 3 | Morphology optimization of photoactive layers in organic solar cells显示文摘Organic solar cells(OSCs)have unique advantages of light weight,low-cost solution processing,and capability to be fabricated into flexible and semitransparent devices,which are widely recognized as a promising photovoltaic technology.Photoactive layers of the OSCs are composed of a blend of a p-type organic semiconductor as a donor(D)and an n-type organic semiconductor as acceptor(A).The morphology of the active layer with D/A nano-scaled aggregation and face-onπconjugated packing,and D/A interpenetrating network is crucial for achieving high photovoltaic performance of the OSCs.Therefore,great efforts have been devoted to control and optimize morphology of the active layers.This perspective focuses on the morphological control by solvent/solid processing additives and the morphology optimization by postdeposition treatment with thermal annealing and/or solvent vapor annealing,which have been extensively adopted and exhibit promising positive effect in optimizing the morphology.Representative examples are given and discussed to understand the foundation of the postdeposition treatments on tuning the morphology.Insights into the role of the postdeposition treatments and additive treatments on the morphology optimization will be beneficial to further improvement in morphology optimization for practical organic photovoltaic application. | Chaohua Cui Yongfang Li | 2021 | Aggregate2021，2，2： | 2 |
| 4 | Synergistic effect of solvent and solid additives on morphology optimization for high-performance organic solar cells显示文摘Controlling the photoactive layer morphology towards nanoscale bi-continuous donor/acceptor interpenetrating networks is a key issue to build high-performance organic solar cells(OSCs).Due to the distinct properties between donor and acceptor materials,casting an active layer from a single solvent solution usually results in either insufficient or excessive phase separation that reduces the device performance.In comparison to the fullerene acceptors with closed-cage structures,the currently dominant non-fullerene acceptors possess the similar anisotropicπ-πinteractions with p-type organic semiconductor donors,giving rise to the complexity of the morphology regulation.Herein,we employ 4,4′-dimethoxyoctafluorobiphenyl(OFP)with strong crystallinity as a volatile solid additive to optimize the active layer morphology of OSCs.The synergistic effect of 1-chloronaphthalene(CN)and OFP as dual additives shows supreme capability on optimizing the morphology over the conventional additive of CN,which is in favor of improving charge transport and suppressing charge recombination for higher fill factors in various systems.In particular,the PTQ10:m-BTP-C6 Ph-based device processed by the additive showed a remarkable powerconversion efficiency(PCE)of 17.74%,whereas the control device processed by CN additive yielded a relatively lower PCE of16.45%. | Chenling Fan Hang Yang Qing Zhang Sunan Bao Hongyu Fan Xianming Zhu Chaohua Cui Yongfang Li | 2021 | Science China Chemistry2021，64，11： | 0 |
| 5 | Effects of Heteroatom Substitution on the Photovoltaic Performance of Donor Materials in Organic Solar Cells显示文摘CONSPECTUS:Over the past few years,the innovation of narrow bandgap acceptor combined with wide bandgap donor materials significantly promotes the power conversion efficiencies(PCEs)of organic solar cells(OSCs)to exceed 18%.To build a state-of-the-art OSC,absorption spectra,frontier molecular orbital energy levels,molecular packing and crystallinity,and charge carrier mobilities of the photovoltaic materials should be considered in their molecular design.The donor and acceptor materials are the key components determining the photovoltaic performance of the OSCs.The side chain engineering on the conjugated backbone is a critical strategy to optimize the photovoltaic properties of the donor materials.In this Account,we focus on the topic of heteroatom substitution on the molecular backbone of the donor materials for improving their photovoltaic performance,aiming to provide in-depth understanding of the molecular structure optimization for the design of stateof-the-art photovoltaic materials. | Hang Yang Chaohua Cui Yongfang Li | 2021 | Accounts of Materials Research2021，2，11： | 0 |
| 6 | Metallated conjugation in small-sized-molecular donors for solution-processed organic solar cells显示文摘Four metallated conjugated oligothiophenes,S-1,S-2,S-3 and S-4,with platinum(II)aryleneethynylenes as the electron-rich building block were synthesized to investigate their physicochemical and photovoltaic properties.These small molecules possess fairly low-lying HOMO energy levels which match with the LUMO energy level of the electron acceptor PC70BM([6,6]-phenyl-C71-butyric acid methyl ester).Using the simple process of spin-coating solution fabrication technique,S-1:PC70BM(1:4,w/w)based organic solar cells exhibiting a high Voc of 0.913 V,with a PCE value of 0.88%were developed.In contrast,the OSC device based on S-2:PC70BM(3:7,w/w)displayed a higher PCE of 1.59%with a higher Jsc value of 5.89m A cm–2.The device based on S-4:PC70BM(1:4,w/w)exhibited a PCE value of 1.56%,with a Voc of 0.917 V. | Chaohua Cui Yunye Zhang Wallace C.H.Choy Hua Li Wai-Yeung Wong | 2015 | Science China Chemistry2015，58，2： | 0 |
| 7 | Impact of isomers on the photovoltaic properties of polymerized small-molecule acceptors显示文摘All-polymer solar cells(all-PSCs)have attracted tremendous research interests due to their inherent advantages of excellent mechanical flexibility,film formation,and morphological stability.Recently,the development of polymerized small-molecule acceptors(PSMAs)has boosted the power conversion efficiencies(PCEs)of all-PSCs to over 18%.Polymerization sites on the terminal groups of small molecule acceptors play a decisive role in determining the absorption spectra,frontier molecular orbital energy levels,molecular packing and crystallinity,charge carrier mobilities and device performance of polymer acceptors.In this perspective,we focus on the latest advances of region-specific terminal groups and region-regular PSMAs,aiming to summarize the relationship between molecular structure–physicochemical properties–active layer morphology–device performance.Finally,the future design directions and challenges faced by region-specific terminal groups and regionregular PSMAs are discussed.In this Perspective article,we advocate that the region-regular PSMAs approach can advance better designs for high-performance polymer acceptors with good batch-to-batch reproducibility. | Hang Yang Chaohua Cui | 2022 | Energy Reviews2022，1，2： | 0 |
