Progress in Chemistry 23 ( 5 ) 991 - 1013 2011年05月

記述言語：英語掲載種別：研究論文（学術雑誌）

Polymer solar cell has attracted considerable attention due to its advantages, such as light weight of device, simple process of production, and low-cost fabrication process. Bulk heterojunction polymer solar cell (BHJ-PSC) is one of the device with excellent performance. In this paper, we review the recent progress of the BHJ-PSC. First, we introduce the device structure and the work principle of the BHJ-PSC with the focus on the progress of donor and acceptor material. Furthermore, we discuss several important factors for effecting morphology of the active layer, such as solvents, additives, ratio of donor and accepter, and annealing condition. In addition, tandem cell and inverted cell are also introduced. Finally, the solutions to improve performance of the BHJ-PSC and the application prospects of the BHJ-PSC are presented.

Journal of Porphyrins and Phthalocyanines 15 ( 5-6 ) 421 - 432 2011年05月

記述言語：英語掲載種別：研究論文（学術雑誌）

A saddle-distorted porphyrin bearing a carboxyl group as a hydrogen-bonding site on a meso-phenyl group was synthesized and characterized. A supramolecular structure with intermolecular hydrogen bonding was revealed by X-ray diffraction analysis. The effects of the peripheral carboxyl group on the physicochemical properties of the porphyrin as well as on self-assembly were investigated by spectroscopic measurements in solutions. The redox properties of the porphyrin and its Zn(II) complex were also studied by electrochemical measurements and their application to dye-sensitized solar cells was examined. © 2011 World Scientific Publishing Company.

We synthesized a low-cost, highly catalytic tungsten carbide that was embedded in ordered mesoporous carbon WC-OMC. This was used as a counter electrode CE in dye-sensitized solar cells _DSCs_. For comparison, we also evaluated the catalytic activity of bare WC, and several normal carbon materials for the organic redox couple of thiolate/disulfide.

Sunny prospects for renewable energy: Molybdenum and tungsten carbides embedded in ordered nanomesoporous carbon materials as well as Mo2C and WC are proposed as alternatives to the expensive platinum counter electrode (Pt CE). The preparation of the CEs was optimized, and the dye-sensitized solar cells (DSCs; see picture) equipped with these CEs show a higher energy conversion efficiency than those devices with a Pt CE.

Effects of hydroxyl group numbers of coadsorbents on photovoltaic performances of dye-sensitized solar cells 査読有り

Lin H., Liu Y., Liu C., Li X., Shen H., Zhang J., Ma T., Li J.

記述言語：英語掲載種別：研究論文（学術雑誌）

Surface treatment of ruthenium dye (Bu4N)2[Ru(dcbpyH) 2(NCS)2]-sensitized TiO2 films using diethyl 4-methylphenylphosphonate as a coadsorbent results in large improvements in DSC performance, 24% larger overall conversion efficiency and 55 mV higher open-circuit voltage without current penalty. Introducing another two coadsorbents ethyl 4-methylphenylphosphonate and 4-methoxyphenylphosphonic acid brings in negative effects. Analysis by impedance spectroscopy indicated that this was attributed to different numbers of proton-releasing hydroxyl groups of the coadsorbents and consequently different proton-adsorbing chemical environments on the surface of TiO2 photoanodes. © 2010 Elsevier B.V.

In order to improve the performance of the dye-sensitized solar cells based on ZnO films, ZnO nanoparticles of different size and morphology were prepared by hydrothermal and solvothermal synthesis methods. Electrodes applied to dye-sensitized solar cell were prepared by the screen-printing method. The effects of ZnO nanoparticles of different size and morphology on the photovoltaic characteristics of dye-sensitized ZnO solar cells were investigated. The results show that: The short-circuit current density and the energy conversion efficiency of the ZnO nanosheets DSSC are 0.13 mA/cm 2 and 0.02%. The short-circuit current density and the energy conversion efficiency of cells prepared with ZnO nanorods with diameter 500nm and length 5μm are 1.91 mA/cm2 and 0.03%.The best performance achieved in the present work was a conversion efficiency of 3.46% for the cells prepared with ZnO nanoparticles with diameters 80nm. © (2011) Trans Tech Publications.

Dye-sensitized solar cells (DSSC) are currently attracting widespread interest for the conversion of sunlight into electricity because of their low cost and high efficiency. In these cells, photo-anode is one of the key components for high power conversion efficiencies. In this paper, TiO 2 nanopowders were prepared by the non-hydrolytic sol-gel method using TiCl4 as precursor, absolute ethanol and isopropanol as oxygen donor. Several different TiO2 nanopowders were used to fabricate TiO2 solar cells, and properties of TiO2 solar cells were characterized. The solar cell prepared with grainsize 50∼80nm TiO 2 nanopowders generated a short-circuit photocurrent of 13.17 mA/cm2, an open-circuit photovoltage of 789 mV, a fill factor of 69.8% and the efficiency of 7.25% under the light intensity of 100 mW/cm 2. © (2011) Trans Tech Publications.

The five photocatalysts of SrTiO 3 were prepared by molten salt synthesis (MSS) process and solid state reaction (SSR) process. The properties of the obtained samples were characterized by X-ray diffraction, BET and scanning electron microscope. The samples obtained by the MSS process showed the cubic particles. NiO x as a co-catalyst was coated on the surface of SrTiO 3 by an impregnated process, and the photocatalysis reactions for water splitting were evaluated with the NiO x-SrTiO 3 catalyst. The experimental results show that the photocatalysis reactivity of SrTiO 3 is influenced obviously by the synthesis process. And the reactivity of SrTiO 3 prepared by MSS process with NaCl is better than that of SSR process. The water can be split into hydrogen and oxygen effectively.

Dye-sensitized solar cell (DSC) is a new class of green photovoltaic cell based on photosynthesis principle in nature. We fabricated the DSCs using ten natural dyes as sensitizers, which extracted from the materials existing in nature and our life, such as flowers, leaves, fruits, traditional Chinese medicines, and beverages. The photoelectrochemical performances of the DSCs based on the dyes showed that the open circuit voltages (Voc) varied from 0.49-0.69 V and the short circuit photocurrent densities (Jsc) were in the range of 0.74-2.69 mA/cm2. It is expected that the energy conversion efficiency can be further improved by introducing functional group and optimizing structure of natural dye. ©2010 IEEE.
