A novel hierarchical TiO(2) flower consisting of anatase TiO(2) nanotubes on a Ti foil substrate has been prepared via a mild hydrothermal reaction of TiO(2) nanoparticles/Ti foil. The photovoltaic performance of DSSC based on hierarchical TiO(2) flowers/Ti (7.2%) is much higher than that of TiO(2) nanoparticle/Ti (6.63%) because of its superior light scattering ability and fast electron transport. Moreover, full flexible DSSC based on the novel hierarchical TiO(2) flowers/Ti foil photoelectrode and electrodeposited poly(3,4-ethylenedioxythiophene) (PEDOT) on indium tin oxide-coated poly(ethylene terephthalate) (ITO-PET) counter electrode shows a significant power conversion efficiency of 6.26%, accompanying a short-circuit current density of 11.96 mA cm(-2), an open-circuit voltage of 761 mV and a fill factor of 0.69.
一种新型的 TiO(2) 花状结构，由 Ti 箔基底上的锐钛矿 TiO(2) 纳米管组成，是通过 TiO(2) 纳米粒子/Ti 箔的温和水热反应制备的。基于分层 TiO(2) 花/Ti（7.2%）的 DSSC 的光伏性能远高于 TiO(2) 纳米粒子/Ti（6.63%），因为它具有优越的光散射能力和快速的电子传输能力。此外，基于新型分层 TiO(2) 花/Ti 箔光电极和在铟锡氧化物涂覆的聚对苯二甲酸乙二醇酯（ITO-PET）对电极上电沉积的聚（3,4-亚乙基二氧噻吩）（PEDOT）的全柔性 DSSC 显示出显著的 6.26%功率转换效率，伴随着 11.96 mA cm(-2) 的短路电流密度、761 mV 的开路电压和 0.69 的填充因子。
