电极材料是纤维太阳能电池的关键组件，当以适当的方式与活性层（用于光吸收和电荷产生）结合时，它们可以设计和制造高效和创新的器件结构。在这里，我们应用碳纳米管纱线作为对电极，与 CdSe 纳米线接枝主电极（Ti 线）相结合，制造纤维和织物形光电化学电池，功率转换效率在 1% 至 2.9% 范围内。与传统的金属线或碳纤维相比，加捻长纳米管纱线具有良好的导电性和机械柔韧性，这有利于制造具有多种配置的太阳能电池。我们工艺的一个独特之处在于，我们不是制造单独的纤维细胞，而是直接将带有主电极的单根或多根纳米管纱线编织成功能性织物。我们的结果证明了半导体纳米线和碳纳米管在编织光伏发电中的应用前景。
Electrode materials are key components for fiber solar cells, and when combined with active layers (for light absorption and charge generation) in appropriate ways, they enable design and fabrication of efficient and innovative device structures. Here, we apply carbon nanotube yarns as counter electrodes in combination with CdSe nanowire-grafted primary electrodes (Ti wire) for making fiber and fabric-shaped photoelectrochemical cells with power conversion efficiencies in the range 1% to 2.9%. The spun-twist long nanotube yarns possess both good electrical conductivity and mechanical flexibility compared to conventional metal wires or carbon fibers, which facilitate fabrication of solar cells with versatile configurations. A unique feature of our process is that instead of making individual fiber cells, we directly weave single or multiple nanotube yarns with primary electrodes into a functional fabric. Our results demonstrate promising applications of semiconducting nanowires and carbon nanotubes in woven photovoltaics.
