中文摘要
本综述的创新之处在于将单一金属、二元合金和三元合金用作染料敏化太阳能电池（DSSCs）中的对电极（CE）。合金可分为二元合金和三元合金。本文描述了用于DSSC对电极中金属的一些性质，展示了采用这些合金的器件的功率转换效率（PCE），并将其与使用无铂对电极的器件进行了比较。本文还阐述了PCE与电化学阻抗谱（EIS）、循环伏安法（CV）以及Tafel极化参数之间的关系。结论表明，通过选用组分金属之间具有良好相容性的二元和三元合金，可进一步提高DSSC的效率。使用二元合金和三元合金的器件效率分别达到了最高值9.08%和9.07%。
English Abstract
The novelty of this review is the use of single metal, binary and ternary alloy as counter electrode (CE) in dye-sensitized solar cells (DSSCs). Alloy can be divided into binary and ternary alloys. Some properties of the metals used in CE in DSSC are described. The power conversion efficiency (PCE) of the device using those alloys are presented and compared with that of the device employing Pt free CE. This paper also describes the relationship of the PCE with the electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and Tafel polarization parameters. As conclusions, the efficiency of the DSSC can be further improved by using binary and ternary whose metal components are compatible to each other. The efficiency of the device using binary and ternary alloy reached the highest value of 9.08 and 9.07%, respectively.
