中文摘要：

染料敏化太阳能电池（DSC）由于其工艺简单、成本低廉、理论光电转换效率高，逐渐成为硅基太阳能电池的有力竞争者。DSC电池的光阳极主要起到对染料分子中激发出来的电子进行传导的作用，其光阳极薄膜大多数是由氧化物纳米晶制备的。氧化物纳米晶存在大量界面电阻，导致能量势垒，从而使染料分子中光生电子一空穴对不能有效分离，制约了DSC电池光电转换效率的提高。而高长径比的一维氧化物纳米光阳极薄膜有望降低界面电阻，促进电子一空穴对的有效分离，将是DSC电池光阳极材料开发的重要发展方向。详细论述了染料敏化太阳电池用一维纳米氧化物光阳极薄膜的研究进展。

英文摘要：

Dye-sensitized solar cell（DSC）, a new type solar cell, wilt become a powerful competitor with silicon- based solar cell due to its simple technology, low production cost and high theoretical conversion efficiency, and thus cause extensive attention. In DSSC, the oxide photoanode is in charge of transferring electrons excitated from the dye molecule. At present,most researchers use oxide nano-crystals to prepare the photoanode films, but a great deal of interface resistance among the oxide nano-crystals, will form the energy barriers. As a result, the electron-hole pairs, generated from the exited dye molecule absorbing photons, can＇t be separated efficiently. The photoanode, prepared by one-dimensional nanomaterials with large aspect ratio, may markedly decrease the interface resistance between adjacent particles, improve the transfer rate of electrons and contribute to the fast separation of electron-hole pairs, which will be an important direction in the development of photoanode materials. In this paper, the research development of the one-dimensional nano-oxide photoanode films for DSC is discussed in detail.
