| 摘 要： | 本文提出了一种新型染料敏化太阳能电池的叠层结构设计, 其中光阳极由导电玻璃上的第一层TiO2纳米薄膜和不锈钢网上的第二层TiO2纳米薄膜组成, 不同染料间的负反应相比混染共敏方式少. 此结构中引入的金属网, 减少了导电玻璃的使用片数, 从而减少入射光的损失; 同时也解决了两层不同TiO2薄膜间的电连接性问题, 并提高电子传输和收集效率. 此叠层电池的光电转换效率达1.96%, 短路电流为8.4mA/cm2, 相比相同电池厚度的单层电池, 效率提高约62%. 通过阻抗谱分析了叠层电池内部的电子传输, 给出叠层电池的等效电路图. 此外, 还发现电池厚度的增加及电子在不锈钢网表面的复合对光电性能有显著影响.

| Abstract: | A newly structured tandem dye-sensitized solar cell(tandem DSC) based on stainless mesh was introduced,in which the electrode constituted a first TiO2 film on TCO and a second TiO2 film on stainless mesh.Negative inter-action between different dyes in this structure is less than that by normal method of cocktail-dyes dipping.The appli-cation of stainless mesh here reduces the loss of incident light,solves the problem of electronic connection between two different TiO2 films,as well as improves electron tran... |
