In this work, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/poly(vinylidene fluoride) (PVDF) nanofiber-web-based transparent conducting electrodes (TCEs) were fabricated for use in dye-sensitized photovoltaic textiles. The PEDOT:PSS solution was mixed with dimethyl sulfoxide (DMSO) solvent, and the PEDOT:PSS/DMSO mixture was applied on the PVDF nanofiber web using a simple brush-painting technique to prepare ultrathin and -lightweight, highly transparent TCEs. When the PVDF nanofiber web was treated with a 3:7 PEDOT:PSS and DMSO mixture (P3D7 sample), it exhibited ∼84% transmittance at a wavelength of 550 nm with an average sheet resistance of ∼1.5 kΩ/sq. In addition, it showed a figure of merit (FOM) of 0.104 × 10 Ω. In the trial test, the P3D7 TCE-based photovoltaic textile exhibited an average voltage of 73.20 mV and an average current of 0.44 mA/cm.
在这项工作中，制备了基于聚（3,4 - 亚乙基二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT:PSS）/聚偏氟乙烯（PVDF）纳米纤维网的透明导电电极（TCE），用于染料敏化光伏纺织品。将PEDOT:PSS溶液与二甲基亚砜（DMSO）溶剂混合，然后使用简单的刷涂技术将PEDOT:PSS/DMSO混合物涂覆在PVDF纳米纤维网上，以制备超薄、轻质且高度透明的TCE。当PVDF纳米纤维网用3:7的PEDOT:PSS和DMSO混合物处理（P3D7样品）时，在550 nm波长下其透光率约为84%，平均方阻约为1.5 kΩ/sq。此外，它的品质因数（FOM）为0.104×10Ω。在试验测试中，基于P3D7 TCE的光伏纺织品平均电压为73.20 mV，平均电流为0.44 mA/cm²。
