Textile-structured solar cells are frequently discussed in the literature due to their prospective applications in wearable devices and in building integrated solar cells that utilize their flexibility, mechanical robustness, and aesthetic appearance, but the current approaches for textile-based solar cells-including the preparation of fibre-type solar cells woven into textiles-face several difficulties from high friction and tension during the weaving process. This study proposes a new structural concept and fabrication process for monolithic-structured textile-based dye-sensitized solar cells that are fabricated by a process similar to the cloth-making process, including the preparation of wires and yarns that are woven for use in textiles, printed, dyed, and packaged. The fabricated single-layered textile-based dye-sensitized solar cells successfully act as solar cells in our study, even under bending conditions. By controlling the inter-weft spacing and the number of Ti wires for the photoelectrode conductor, we have found that the performance of this type of dye-sensitized solar cell was notably affected by the spacing between photoelectrodes and counter-electrodes, the exposed areas of Ti wires to photoelectrodes, and photoelectrodes' surface morphology. We believe that this study provides a process and concept for improved textile-based solar cells that can form the basis for further research.
纺织结构太阳能电池由于其在可穿戴设备和建筑集成太阳能电池中的潜在应用而经常在文献中被讨论，这些应用利用了它们的灵活性、机械鲁棒性和美观的外观，但目前用于纺织太阳能电池的方法——包括将纤维型太阳能电池编织到纺织品中的方法——在编织过程中面临着高摩擦和张力的困难。本研究提出了一种用于整体结构纺织基染料敏化太阳能电池的新结构概念和制造工艺，该工艺类似于制布工艺，包括用于纺织品的电线和纱线的制备、编织、印刷、染色和封装。所制造的单层纺织基染料敏化太阳能电池在我们的研究中甚至在弯曲条件下都能成功作为太阳能电池发挥作用。通过控制纬纱间距和光电导电极的钛丝数量，我们发现这种类型的染料敏化太阳能电池的性能明显受到光电极和对电极之间的间距、钛丝暴露在光电极上的面积以及光电极表面形貌的影响。我们相信，这项研究为改进的纺织基太阳能电池提供了一种工艺和概念，可为进一步的研究奠定基础。
