染料敏化太阳能电池可被视为补充当前光伏系统的未来候选者；然而，扩大染料敏化太阳能电池的规模是一个复杂的问题。挑战之一是模块电阻，其中包括透明导电氧化物基板的电阻。通过增大基板面积，模块内部串联电阻增大，导致填充因子下降；因此，必须在模块中引入电荷收集器。在这项工作中，银线被纳入微型模块设计中，并且分别在工作电极侧和对电极侧的两个银集电器之间的距离的依赖性，并且说明了模块串联电阻。由 7 个电池组成的模块，银线厚度为 0.60 mm，有效表面积为 23.8 cm(2)，效率达到 4.8%。 (C) 2016 AIP 出版有限责任公司。
Dye-sensitized solar cells can be considered as a future candidate to complement current photovoltaic systems; however, scaling-up the dye-sensitized solar cell is a complicated issue. One of the challenges is the module resistance, which includes the resistance of the transparent conducting oxide substrate. By increasing the substrate area, the internal module series resistance increases, resulting in a decrease of the fill factor; hence, charge collectors must be introduced in the module. In this work, silver lines are incorporated in a mini-module design and the dependence of distance between the two silver current collectors, on the working and counter electrode sides, respectively, and the module series resistance is illustrated. A module of 7 cells with 0.60 mm silver lines, and 23.8 cm(2) of active surface area reached an efficiency of 4.8%. (C) 2016 AIP Publishing LLC.
