| 1 | Low temperature fabrication of high performance and transparent Pt counter electrodes for use in flexible dye-sensitized solar cells显示文摘High performance Pt counter electrode is prepared by using vacuum thermal decomposition at a relatively low (120℃) temperature on a flexible polyethylene naphthalate substrate coated with indium-doped tin oxide for use in flexible dye-sensitized solar cells.The obtained Pt counter electrode shows a good chemical stability,high light transmittance,and high electrocatalytic activity for the I3-/I-redox reaction.The energy conversion efficiency of a flexible dye-sensitized solar cell based on the prepared Pt counter electrode and a TiO 2 /Ti photoanode reaches 5.14% under a simulated solar light irradiation with intensity of 100 mW cm-2. | XIAO YaoMing,WU JiHuai,CHENG CunXi,CHEN Yuan,YUE GenTian,LIN JianMing,HUANG MiaoLiang,FAN LeQing & LAN Zhang Engineering Research Center of Environment-Friendly Functional Materials,Ministry of Education,Institute of Materials Physical Chemistry,Huaqiao University,Quanzhou 362021,China | 2012 | Chinese Science Bulletin2012，57，18： | 10 |
| 2 | Efficiency improvement of flexible dye-sensitized solar cells by introducing mesoporous TiO_2 microsphere显示文摘Mesoporous TiO2microsphere(MTM)was synthesized via a simple solution route and then mixed with commercial TiO2(P25)to form highly homogeneous and stable TiO2colloid by simple hydrothermal treatment.The TiO2colloid was coated onto the plastic conductive substrate to prepare mesoporous TiO2film for flexible dye-sensitized solar cells(DSSCs)by low-temperature heat treatment.The influence of MTM content on the physicochemical properties of the flexible TiO2film was characterized by scanning electron microscope,transmission electron microscopy,X-ray diffraction,energy-dispersive X-ray spectrometer,N2adsorption-desorption isotherms,UV–vis absorption and diffuse reflectance spectra.It is revealed that with increasing the MTM content,the dye-loading capability of TiO2film and light-harvesting efficiency of flexible DSSCs are improved due to MTM having high surface area and acting as a light scattering center,respectively,resulting in the enhancement of photocurrent of flexible DSSCs.However,more and larger cracks having negative effect on the performances of flexible DSSCs are formed simultaneously.Under the optimal condition with MTM content of 20%,a flexible DSSC with overall light-to-electric energy conversion efficiency of 2.74%is achieved under a simulated solar light irradiation of 100 mW cm 2(AM 1.5),with 26%improvement in comparison with DSSCs based on P25 alone. | FAN LeQing CHEN Yuan WU JiHuai LI ZhaoLei XIAO YaoMing HUANG MiaoLiang YU HaiJun | 2013 | Science China Chemistry2013，56，10： | 5 |

| 5 | Preparation of porous nanoparticle TiO_2 films for flexible dye-sensitized solar cells显示文摘A TiO2 paste was prepared by mixing commercial TiO2 (P25), ethanol, distilled water and a small amount of Ti (IV) tetrai-sopropoxide (TTIP), following by a hydrothermal treatment. Before hydrothermal treatment, a stirring for 48 h can prevent cracking TiO2 films. TTIP significantly promote the chemical connection between TiO2 particles and its adherence to the substrate, the TTIP amount of 6 mol% is suitable. UV irradiation can remove some impurities and water from the TiO2 film with an optimal time of 2 h. Transmission electron microscopy, X-ray diffraction, scanning electron microscopy and photovoltaic tests are charac- terized and measured. Shortcircuit current density, open-circuit voltage, fill factor and photoelectric conversion efficiencies for the fabricated flexible dye-sensitized solar cell are 7.20 mA cm-2, 0.769 V, 0.686 and 3.84%, respectively, under irradiation with a simulated solar light of 100 mW cm-2. | WANG Yue WU JiHuai LAN Zhang XIAO YaoMing LI QingBei PENG FuGuo LIN JianMing HUANG MiaoLiang | 2011 | Chinese Science Bulletin2011，56，24： | 3 |

| 10 | The effect of dispersion of TiO_2 nanoparticles on preparation of flexible dye-sensitized photoanodes显示文摘Generally, nanoparticles are easy to aggregate due to their nano sizes, which influence the physical and chemical properties. In this work, a dispersion treatment of the TiO2 nanoparticles with different average sizes was employed to improve the dispersion of TiO2 nanoparticles, in order to prepare flexible photoanodes for dye-sensitized solar cells (DSCs) with novel photovoltaic properties at a low temperature. The effects of dispersion treatment on the dispersion of TiO2 nanoparticles, including the viscosities of the binder-free TiO2 paste, the morphologies and textural properties of nanoparticle-TiO2 films, and the photovoltaic properties of the flexible DSCs, were investigated. Flexible indium-tin oxide (ITO)-coated polyethylene naphthalate (PEN) substrates with sputter deposited Pt were employed as the transparent flexible counter electrodes. A short-circuit photocurrent density of 9.62 mA·cm 2, an open-circuit voltage of 0.757 V, a fill factor of 0.589 and an overall light-to-energy conversion efficiency of 4.29% for the flexible DSCs under AM1.5 illumination of 100 mW cm 2 were obtained with dispersion treatment. A 30.8% increment of the energy conversion efficiency for DSCs made by dispersion treatment was obtained compared with that made without dispersion treatment. | ZHAO XiaoChong LIN Hong LIU YiZhu LI Xin YANG Pan CHEN HuiYuan WANG Gang LI JianBao | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，7： | 0 |
