| 2 | Copper/cuprous sulfide electrode: preparation and performance显示文摘Cuprous sulfide(Cu2S) is a direct band-gap p-type semiconductor with excellent ionic/electronic hybrid conductivity. Although Cu/Cu2S/sulfide or polysulfide system is adopted as counter electrode of quantum-dots-sensitized solar cells(QDSSC), the electrode process is seldom reported. Here, the electrochemical growth of Cu2 S film on a copper(Cu) surface, the redox behaviors of sulfide and polysulfide, and the all-in-solid charge-transfer properties of Cu2 S film are investigated. It is clarified that the copper electrode simultaneously undergoes an activated process, a membrane growth process, and a redox phase transformation process. The solid charge-transfer capability of Cu2 S is quantified with a high exchange-current density of 2.27 A/cm2, which elucidates that the Cu/Cu2 S electrode is a qualified material for counter electrodes of QDSSC. These results aid understanding of the physicochemical mechanism of QDSSC with a polysulfide electrolyte and Cu/Cu2 S counter electrode. | Lina Xiao Ding Yuan Pei Li Li Huang Bing-Wei Mao Dongping Zhan | 2015 | Science China Chemistry2015，58，6： | 0 |
| 3 | 不同尺寸纳米TiO_2多孔薄膜中陷阱态分布研究显示文摘纳米Ti O2多孔薄膜中陷阱态的数量与分布可影响光致电子的传输与复合,进而影响染料敏化太阳电池(DSSCs)的性能.本文采用三电极体系,基于电化学阻抗谱(EIS)及循环伏安法(CV),研究了分别由10,20,80和200 nm Ti O2纳米颗粒组成的多孔薄膜中陷阱态的分布情况,结果表明,多孔薄膜中陷阱态的含量随颗粒的增大而减少.同时,光电子能谱(XPS)表征结果显示,多孔薄膜中Ti3+及氧空位的含量随颗粒增大有所减少.本研究工作为不同尺寸纳米颗粒的多孔薄膜对电池光伏性能影响提供了又一微观机制说明. | 马艳梅 丁勇 桃李 李广 胡林华 戴松元 | 2015 | 中国科学:化学2015，45，6： | 0 |
| 4 | Regulating the mesogenic properties of imidazolium salts by modifying N^3-substituents显示文摘In this study, a series of imidazolium salts with different N3-substituents(3-position: methyl, vinyl, ethyl, n-propyl, n-butyl)-based ionic-liquid crystals with iodide as counterion(ILCs) are synthesized and characterized, with the aim of regulating the mesogenic properties of imidazolium salts. The imidazolium salts-based ionic-liquid crystals are characterized by thermal analysis, polarized optical microscopy, X-ray powder diffraction, and single-crystalline diffraction. Liquid crystalline phase with a Smectic A phase interdigitated bilayer structure is observed. The mesophase temperature range decreases with the increase of the alkyl chain length of N3-substituent. While when vinyl is attached to the N3 position, intermolecular ?-? interactions are formed in adjacent layers, which exert a positive effect on the formation of mesophase. The layer-spacing of imidazolium salts keeps increasing with the increase of the alkyl chain length attached to both the N1 and N3 positions, and gradually decreases with the increasing temperature in liquid crystalline phase. The 1-alkyl-3-vinylimidazolium salt has the smallest layer-spacing, due to the intermolecular ?-? interactions between the vinyl and imidazolium rings in adjacent layers. | Meng Wang Xu Pan Jian Chen Songyuan Dai | 2015 | Science China(Information Sciences)2015，58，12： | 0 |
