摘　　要：Dye-sensitized solar cell （DSSC） is one of the most rapidly developed solar cells in the past 20 years. Many characterization methods have been employed for further understanding the operational details of the photo- electric conversion in DSSC as well as the evaluation of cell performance. Electrochemical methods have become pow- erful tools for studying the charge transfer and interfacial process. In this review, we introduce and explain the various electrochemical methods used to characterize and analyze DSSC, including current-voltage （I-V） scan measurement, cyclic voltammetry, electrochemical impedance spec- troscopy, intensity-modulated photocurrent spectroscopy, and intensity-modulated photovoltage spectroscopy. In ad- dition, some applications were provided as samples to elucidate electron transfer kinetics, energy levels and electrocatalytic activity of the materials used in DSSC.染料敏化太阳能电池(DSSC)在过去的二十几年间发展迅速,由于DSSC本质上是一类电化学太阳能电池,电化学研究方法无论在DSSC的性能表征,还是在研究电池机理、电荷转移和界面过程等方面均发挥着重要作用.本文着重介绍了多种常用电化学方法的原理及其在DSSC表征及研究中的应用,包括线性伏安扫描、循环伏安、电化学阻抗及新型的电化学频谱技术,如强度调制光电流谱、强度调制光电压谱等.特别是从实用的角度通过结合具体实例,阐明电化学方法在DSSC的性能表征、电池工作机制、电荷转移和界面过程研究等方面的应用.
