| 1 | Formation of efficient dye-sensitized solar cells by introducing an interfacial layer of hierarchically ordered macro-mesoporous TiO_2 film显示文摘Hierarchically ordered macro-mesoporous TiO2 films (Ti-Ma-Me) were fabricated on fluorine-doped tin oxide (FTO) substrates through the confinement self-assembly method. The prepared Ti-Ma-Me possesses periodically ordered structure and a large specific surface area, which was applied as an interfacial layer between the nanocrystalline TiO2 film (P25-TiO2) and FTO electrode in the dye-sensitized solar cell (DSSC). The introduction of a Ti-Ma-Me interfacial layer increased the shortcircuit current density (Jsc) from 7.49 to 10.65 mA/cm2 and the open-circuit voltage (Voc) from 0.65 to 0.70 V as the result of its improved light harvesting efficiency by allowing for the high roughness factor and enhanced multiple internal reflection or scattering as well as reducing the back-transport reaction by blocking direct contact between the electrolyte and FTO electrode. Therefore, the photovoltaic conversion efficiency (η) was improved by 83% from 3.04% to 5.55%, as compared to a device using a bare P25 TiO2 photoanode. | HALPERT Jonathan E | 2011 | Science China Chemistry2011，54，6： | 6 |
| 2 | 有序宏孔-介孔TiO_2薄膜的制备及其在染料敏化太阳能电池中的应用显示文摘我们使用表面活性剂P123和聚苯乙烯球双模板技术,合成了多级有序的宏孔/介孔TiO2薄膜,并将其与P25多孔薄膜复合形成双层结构的染料敏化太阳能电池光阳极.实验结果表明,宏孔/介孔TiO2薄膜层的引入,有效地提高了光阳极对太阳光的散射以及捕获能力,从而提高了染料敏化太阳能电池的光电转化效率.与使用单一P25光阳极的染料敏化太阳能电池相比,双层TiO2结构的染料敏化太阳能电池所产生的短路光电流密度从7.49上升到了10.65mA/cm2,开路电压也从0.65提高到了0.70V.在太阳光强度为AM1.5时所测得的光电转化效率表明,双层TiO2结构的染料敏化太阳能电池的光电转化效率为5.55%,比单层P25结构的染料敏化太阳能电池的光电转化效率提升了83%. | 杜江 赖小勇 HALPERT Jonathan E 杨宇 王丹 | 2011 | 中国科学:化学2011，41，7： | 1 |
