ABSTRACT

Highly conductive, transparent and flexible planar electrodes were fabricated using interwoven silver nanowires and single-walled carbon nanotubes (AgNW:SWCNT) in a PEDOT:PSS matrix via an epoxy transfer method from a silicon template. The planar electrodes achieved a sheet resistance of 6.6 ± 0.0 Ω/□ and an average transmission of 86% between 400 and 800 nm. A high figure of merit of 367 Ω−1 is reported for the electrodes, which is much higher than that measured for indium tin oxide and reported for other AgNW composites. The AgNW:SWCNT:PEDOT:PSS electrode was used to fabricate low temperature (annealing free) devices demonstrating their potential to function with a range of organic semiconducting polymer:fullerene bulk heterojunction blend systems.

Figure 3: Transmission (%T) and reflectivity (%R) of an ITO and planar AgNW:SWCNT:PEDOT:PSS nanocomposite electrode corrected for the substrate contribution. The sheet resistances, shown on the right, are an average of 15 measurements on 3 separate 25 mm2 samples.

Mentions: The transmission of the resulting electrode was relatively flat across the wavelength range 400–800 nm with an average transmission of 86.0 ± 1.4% and an average reflectivity of 3.4 ± 0.3% as shown in figure 3. In contrast, the commercial ITO electrode had an average transmission of 93.0 ± 7% and average reflectivity of 7 ± 4%. Typically the planarizing/adhesion layer used to create the smooth electrode surface improves the overall transmission of the electrode and thus the figure of merit substantially.
