Increasing demands for wearable energy sources and highly flexible, lightweight photovoltaic devices have stimulated the development of textile-structured solar cells. However, the former approach of wire-type solar cell fabrication, followed by weaving of these devices, has had limited success, due to device failure caused by high friction forces and tension forces during the weaving process. To overcome this limitation, we present a new approach for textile solar cell fabrication, in which dye-sensitized solar cell (DSSC) electrodes are incorporated into the textile during the weaving process, using the textile warp as a spacer to maintain the DSSC structure. Porous, dye-loaded TiO2-coated holed metal ribbon and Pt nanoparticle-loaded carbon yarn were used as the photoanode and counterelectrode, respectively. The highly flexible textile-based solar cell was fabricated using a common weaving process with a loom. The inserted DSSCs in the textile demonstrated an energy conversion efficiency of 2.63% (at 1 sun, 1.5 A.M.). Our results revealed that additional performance enhancement was possible by considering other electrode materials and textile structures, as well as where and how the DSSC electrodes are inserted. In addition, we demonstrated that the inserted DSSCs could be electrically connected using a parallel configuration.
对可穿戴能源以及高度灵活、轻便的光伏设备的需求不断增加，推动了纺织结构太阳能电池的发展。然而，以前那种先制造线状太阳能电池，然后将这些器件编织在一起的方法，由于在编织过程中高摩擦力和张力导致器件失效，取得的成功有限。为克服这一限制，我们提出了一种制造纺织太阳能电池的新方法，即在编织过程中将染料敏化太阳能电池（DSSC）电极融入纺织品中，利用纺织经线作为间隔物来维持DSSC结构。多孔的、负载染料的TiO₂ 涂层带孔金属带和负载Pt纳米颗粒的碳纱分别用作光阳极和对电极。使用普通织机通过常规编织工艺制造出了高度灵活的基于纺织品的太阳能电池。纺织品中插入的DSSC显示出2.63%的能量转换效率（在1个太阳光照强度下，上午1:30）。我们的结果表明，通过考虑其他电极材料和纺织结构，以及DSSC电极的插入位置和方式，有可能进一步提高性能。此外，我们证明了插入的DSSC可以采用并联配置进行电连接。
