摘要
由于其在光伏领域的特殊应用，在柔性衬底上生长一维单晶TiO2纳米结构受到了广泛的关注。本文采用“溶解生长”的方法，在钛基碳纤维上生长了矩形束状TiO2纳米棒(NR)阵列。在强酸溶液中腐蚀后，每个纳米棒被蚀刻成许多小的纳米线。采用蚀刻TiO2 nrs涂层CFs作为光阳极制备了管状染料敏化太阳能电池。在100 mW cm-2 AM 1.5照明下，绝对能量转换效率为1.28%。这项工作展示了一种在柔性衬底上生长束状TiO2 NRs的创新方法，可以应用于能量收集和存储的柔性设备。
Rectangular Bunched Rutile TiO2 Nanorod Arrays Grown on Carbon Fiber for Dye-Sensitized Solar Cells
Because of their special application in photovoltaics, the growth of one-dimensional single-crystalline TiO2 nanostructures on a flexible substrate is receiving intensive attention. Here we present a study of rectangular bunched TiO2 nanorod (NR) arrays grown on carbon fibers (CFs) from titanium by a “dissolve and grow” method. After a corrosion process in a strong acid solution, every single nanorod is etched into a number of small nanowires. Tube-shaped dye-sensitized solar cells are fabricated by using etched TiO2 NRs-coated CFs as the photoanode. An absolute energy conversion efficiency of 1.28% has been demonstrated under 100 mW cm–2 AM 1.5 illumination. This work demonstrates an innovative method for growing bunched TiO2 NRs on flexible substrates that can be applied in flexible devices for energy harvesting and storage.
