2Tuning the intermolecular interaction of A_(2)-A_(1)-D-A_(1)-A_(2) type non-fullerene acceptors by substituent engineering for organic solar cells with ultrahigh V_(OC) of ~1.2 V显示文摘For non-fullerene acceptors(NFAs)with linear A_(2)-A_(1)-D-A_(1)-A_(2) backbone,there are three kinds of possible intermolecular interaction,A_(1)-A_(1),A_(1)-A_(2) and A_(2)-A_(2) stacking.Hence,it is a huge challenge to control this interaction and investigate the effect of intermolecular stacking model on the photovoltaic performance.Here,we adopt a feasible strategy,by utilizing different substituent groups on terminal A2 unit of dicyanomethylene rhodanine(RCN),to modulate this stacking model.According to theoretical calculation results,the molecule BTA3 with ethyl substituent packs via heterogeneous interaction between A_(2) and A_(1) unit in neighboring molecules.Surprisingly,the benzyl group can effectively transform the aggregation of BTA5 into homogeneous packing of A_(2)-A_(2) model,which might be driven by the strong interaction between benzyl and A1(benzotriazole)unit.However,different with benzyl,phenyl end group impedes the intermolecular interaction of BTA4 due to the large steric hindrance.When using a BTA-based D-π-A polymer J52-F as donor according to“Same-A-Strategy”,BTA3-5 could achieve ultrahigh open-circuit voltage(VOC)of 1.17–1.21 V.Finally,BTA5 with benzyl groups realized an improved power conversion efficiency(PCE)of 11.27%,obviously higher than that of BTA3(PCE=9.04%)and BTA4(PCE=5.61%).It is also worth noting that the same trend can be found when using other four classic p-type polymers of P3HT,PTB7,PTB7-Th and PBDB-T.This work not only investigates the intermolecular interaction of A_(2)-A_(1)-D-A_(1)-A_(2) type NFAs for the first time,but also provides a straightforward and universal method to change the interaction model and improve the photovoltaic performance.Xiaochen Wang Ailing Tang Jing Yang Mengzhen Du Jianfeng Li Gongqiang Li Qiang Guo Erjun Zhou 2020Science China Chemistry2020,63,11:5

6Gradually modulating the three parts of D-π-A type polymers for high-performance organic solar cells显示文摘Organic solar cells(OSCs)have received great attention for the prominent advantage of low-cost,light-weight and potential for fabricating flexible and semi-transparent device via roll-to-roll printing toward making better use of inexhaustible renewable clean energy during the past years[1-4].Jialing Zhou Peiqing Cong Lie Chen Bao Zhanga Yanfang Geng Ailing Tang Erjun Zhou 2021Journal of Energy Chemistry2021,30,11:1
7PTB7-Th based organic solar cell with a high V_(oc) of 1.05 V by modulating the LUMO energy level of benzotriazole-containing non-fullerene acceptor显示文摘The open-circuit voltage(V_(oc))of classical photovoltaic polymers,such as P3HT and PTB7-Th,are always restricted when combining with fullerene derivatives,due to the difficulty of modulating the energy levels of fullerene derivatives.Thus,design of new non-fullerene small molecule acceptor(NFSMA)is very significant to match with these mature polymer donors and improve the V_(oc)and power conversion efficiency(PCE).Here,a new benzotriazole(BTA)-based NFSMA,BTA7 was synthesized by adopting A_2@A_1ADAA_1@A_2type molecular backbone.By using a strong electron-accepting unit of malononitrile(M)as terminal segment A_2,BTA7 demonstrates strong crystallinity,red-shifted absorption spectrum and down-shifted lowest unoccupied molecular orbital(LUMO)energy levels in comparison with BTA_1and BTA_2.Organic solar cells(OSCs)based on PTB7-Th:BTA7 realized a high V_(oc)of 1.05 V with a moderate PCE of 4.60%.The energy loss(E_(loss)=E_gàe V_(oc))of 0.53 e V is lower than the experiential minimum value of0.6 e V,which indicates PTB7-Th still has large potential to improve the V_(oc)and photovoltaic performance after the development of novel electron acceptors.Bo Xiao Yingjie Zhao Ailing Tang Haiqiao Wang Jing Yang Erjun Zhou 2017Science Bulletin2017,62,18:1

9A small molecular electron acceptor based on asymmetric hexacyclic core of thieno[1,2-b]indaceno[5,6-b']thienothiophene for efficient fullerene-free polymer solar cells显示文摘A novel A-D-A(acceptor-donor-acceptor)type non-fullerene small molecule,A201,consisting of an asymmetric thieno[1,2-b]indaceno[5,6-b^0]thienothiophene(TITT)unit as middle D part and 2-(3-oxo-2,3-dihydroinden-1-ylidene)malononitrile(IC)groups as end-capped A parts was designed and synthesized.The asymmetric TITT building block showed a higher dipole moment of 0.85 Debye(1 Debye=3.33564?10^(à30)cm)compared with the symmetric analogues of indacenodithiophene(IDT)and indacenodithieno[3,2-b]thiophene(IDTT)of 0.098 and 0.13 Debye,respectively.The solution-processed bulk heterojunction solar cells using a benzotriazole(BTA)-based polymer of J71 as donor and A201 as acceptor,showed a power conversion efficiency(PCE)of 9.36%with an open-circuit voltage(V_(oc))of0.88 V,a short-circuit current(J_(sc))of 13.15 m A cm^(à2),and a fill factor(FF)of 0.67,under the illumination of AM 1.5G at 100 m W cm^(à2).The high PCE of this material combination could be attributed to its broad absorption spectrum and the high hole mobility(l_h)and electron mobility(l_e)of 9.56?10^(à4)and 5.17?10^(à4)cm^2V^(à1)s^(à1),respectively.These results indicate that the asymmetric electron-donating segments are promising to construct A-D-A type small molecular acceptors,which could largely enhance the diversity of building blocks to design photovoltaic materials.Wenchao Zhai Ailing Tang Bo Xiao Xiaochen Wang Fan Chen Erjun Zhou 2018Science Bulletin2018,63,13:1
10-1.2 V open-circuit voltage from organic solar cells显示文摘Organic solar cells(OSCs)have achieved rapid advance due to the continuous development of high-performance key materials.Recently,the power conversion efficiencies(PCEs)of OSCs under 1 Sun condition(AM 1.5 G,100 mW/cm2)are striving toward 19%[1−5].The PCE improvement benefits from the largely enhanced short-circuit current density(Jsc)and fill factor(FF).However,these cells show relatively low open-circuit voltage(Voc)around 0.8-0.9 V.Ailing Tang Zuo Xiao Liming Ding Erjun Zhou 2021Journal of Semiconductors2021,42,7:0
11Selective fluorination on donor and acceptor for management of efficiency and energy loss in non-fullerene organic photovoltaics显示文摘Although fluorination has been proved effective to modulate optoelectronic properties and film morphology,knowledge of managing power conversion efficiency(PCE)and energy loss(Eloss)of organic photovoltaics(OPVs)by selective fluorination on the donor and/or acceptor is lacking.Herein we designed and synthesized three 1,2,3-benzotriazole(BTA)-based linear polymers(PE45,PE46 and PE47)with different numbers of fluorine atom substitution on the conjugated phenyl side chain.Two classic non-fullerene acceptors(NFAs)Y5(without fluorination)and Y6(with fluorination)were utilized to manage the device efficiency and energy loss.The results revealed that increasing fluorine substitutions on polymer donor improved the OPV efficiencies when the fluorinated Y6 was used as the acceptor,whereas decreased the PCEs when the non-fluorinated Y5 was used as the acceptor.The energy loss declined with the growing fluorine substitutions on polymer donor,and Y5 systems gave the lower values in comparison with the corresponding Y6 cases.It turns out that PE47:Y6 achieved the highest PCE of 15.58%with an open-circuit voltage(VOC)of 0.84 V(Eloss=0.56 e V)due to the highest and balanced hole/electron mobilities,suppressed bimolecular recombination and fibril network morphology,which is the highest value in the BTA-based polymers.Furthermore,PE47:Y5 attained an ultralow non-radiative energy loss of 0.15 e V,which is one of the lowest values among the reported OPVs.Our work could not only give a direct path on how to manage the efficiency and energy loss by selective fluorination on donor and acceptor,but also show a deep understanding on charge generation,transport and collection induced by selective fluorination.You Chen Peng Lei Yanfang Geng Ting Meng Xiangyu Li Qingdao Zeng Qing Guo Ailing Tang Yufei Zhong Erjun Zhou 2023Science China Chemistry2023,66,4:0
12Side chain engineering of quinoxaline-based small molecular nonfullerene acceptors for high-performance poly(3-hexylthiophene)-based organic solar cells显示文摘Poly(3-hexylthiophene)(P3HT)is one of the most used semiconducting polymers for organic photovoltaics because it has potential for commercialization due to its easy synthesis and stability.Although the rapid development of the small molecular non-fullerene acceptors(NFAs)have largely improved the power conversion efficiency(PCE)of organic solar cells(OSCs)based on other complicated p-type polymers,the PCE of P3HT-based OSCs is still low.In addition,the design principle and structure-properties correlation for the NFAs matching well with P3HTare still unclear and need to be investigated in depth.Here we designed a series of NFAs comprised of acceptor(A)and donor(D)units with an A2-A1-D-A1-A2 configuration.These NFAs are abbreviated as Qx3,Qx3 b and Qx3c,where indaceno[1,2-b:5,6-b′]dithiophene(IDT),quinoxaline(Qx)and 2-(1,1-dicyanomethylene)rhodanine serve as the middle D,bridged A1 and the end group A2,respectively.By subtracting the phenyl side groups appended on both IDT and Qx skeletons,the absorption spectra,energy levels and crystallinity could be regularly modulated.When paired with P3 HT,three NFAs show totally different photovoltaic performance with PCEs of 3.37%(Qx3),6.37%(Qx3b)and 0.03%(Qx3 c),respectively.From Qx3 to Qx3b,the removing of phenyl side chain in the middle IDT unit results in the increase of crystallinity and electron mobility.However,after subtracting all the grafted phenyl side groups on both IDT and Qx units,the final molecule Qx3 c exhibits the lowest PCE of only 0.03%,which is mainly attributed to the serious phase-separation of the blend film.These results demonstrate that optimizing the substituted position of phenyl side groups for A2-A1-D-A1-A2 type NFAs is vital to regulate the optoelectronic property of molecule and morphological property of active layer for high performance P3HT-based OSCs.Bo Xiao Qianqian Zhang Gongqiang Li Mengzhen Du Yanfang Geng Xiangnan Sun Ailing Tang Yingliang Liu Qiang Guo Erjun Zhou 2020Science China Chemistry2020,63,2:0
