染料敏化光电化学太阳能电池是寻找低成本和环境友好型太阳能电池的一个很有前途的候选者。研究最广泛，迄今为止最有效的系统是基于二氧化钛。在本文中，使用纳米结构的ZnO电极在光电化学太阳能电池的可能性进行了研究。各种实验技术（如红外，光电子，飞秒和纳秒激光光谱，激光闪光诱导的光电流瞬态测量，两个和三个电极的光电化学测量）表明，热力学，动力学和电荷传输性能的ZnO和TiO 2是可比的。与TiO2相比，ZnO的制备技术提供了更多的改变颗粒尺寸和形状的可能性。然而，在ZnO的情况下，染料敏化过程更复杂，并且需要小心以实现太阳能电池的最佳性能。(C)2002 Elsevier Science B.V.保留所有权利。
Dye-sensitized photoelectrochemical solar cells constitute a promising candidate in the search for cost-effective and environment-friendly solar cells. The most extensively studied, and to date the most efficient systems are based on titanium dioxide. In this paper, the possibilities to use nanostructured ZnO electrodes in photoelectrochemical solar cells are investigated. Various experimental techniques (e.g. infrared, photoelectron, femtosecond and nanosecond laser spectroscopies, laser flash induced photocurrent transient measurements, two and three-electrode photoelectrochemical measurements) show that the thermodynamics, kinetics and charge transport properties are comparable for ZnO and TiO2. The preparation techniques of ZnO provide more possibilities of varying the particle size and shape compared to TiO2. However, the dye-sensitization process is more complex in case of ZnO and care needs to be taken to achieve an optimal performance of the solar cell. (C) 2002 Elsevier Science B.V.
