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 × 10-3 Ω-1. 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/cm2.
