1Synergistic effect of TiO_2 hierarchical submicrospheres for high performance dye-sensitized solar cells显示文摘The performance of dye-sensitized solar cells(DSCs) could be improved by using rationally designed mesoporous film structure for electron collection, dye adsorption and light scattering. The development of a novel double layer film prepared by TiO_2 hierarchical submicrospheres and nanoparticles was reported in this article. The submicrospheres were composed of rutile nanorods of 10 nm diameter and the length of 150–250 nm, which facilitated fast electron transport, charge collection and light scattering. Using a double layer structure consisting of the 10 wt% film as a dye loading layer and the 50 wt% film as the light scattering layer, C101 sensitizer and liquid electrolyte, DSC yielded power conversion efficiency of 9.68% under 1 sun illumination.Jiang Sheng Linhua Hu Li'e Mo Jichun Ye Songyuan Dai 2017Science China Chemistry2017,60,6:0
2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
