摘要
介绍了染料敏化太阳能电池(DSSC)的结构和基本原理,综述了近年来作为DSSC光阳极的TiO2纳米管、纳米线、纳米棒阵列的制备工艺进展,重点介绍了阳极氧化法制备纳米管和水热法制备纳米线和纳米棒。阐述了通过改进TiO2纳米管提高DSSC效率的几种途径,包括优化纳米管的尺寸、改善纳米管的输运性能、在透明基板上生长纳米管、对纳米管进行表面修饰等。最后展望了TiO2纳米阵列DSSC的研究方向。
Structure and principle of dye-sensitized solar cells (DSSC) are introduced and development in fabri- cation technology of TiO2 nanotube, nanowire and nanorod arrays is reviewed with the emphasis on fabrication of TiO2 nanotube arrays by anodization and fabrication of TiO2 nanowire and nanorod arrays by hydrothermal method. Several methods to enhance photoelectric efficiency of TiO2 nanotube based DSSC are proposed, such as optimizing the length and diameter of TiO2 nanotube, enhancing the transport properties of TiO2 nanotube, fabricating TiO2 nanotube on transparent substrate, and surface modification. Finally, several research areas of TiO2 nanoarrays used in DSSC are prospected.
