摘要
本文全面介绍了基于ZnO光阳极的染料敏化太阳电池的研究和应用现状,特别是ZnO光阳极的制备方法,包括传统的手术刀法、丝网印刷技术和电沉积自组装方法,以及最近发展起来的机械挤压法、化学液相沉积法、化学气相沉积法和低温水热法等,对不同制备薄膜方法的工艺条件和优缺点进行了综述。同时介绍了微/纳米复合结构和直线电子传输对光电转换效率提高的作用。指出了ZnO太阳电池未来发展方向是:探索制备ZnO电极的新形貌和新方法,寻找性能更加优异的染料,以提高ZnO太阳电池的光电转换效率。
The development and application of ZnO in dye sensitized solar cells are reviewed in this paper. Doctorblade, screen printing and self-assembly electro-deposition methods are introduced. Attentions are especially paid on the recent developed methods including mechanical compression, chemical bath deposition, chemical vapor deposition and low temperature hydrothermal methods. The advantages and disadvantages of different methods are compared. Micro-and nanometer composite structure and line electron transport theory are also discussed. It is pointed that the future development in dye sensitized ZnO solar cells is not only exploring new methods and technologies for fabricating ZnO photo-anode, but also synthesizing novel dyes to increase the solar-to-energy conversion efficiency.
