Optical and structural properties of semi-transparent flexible AgNWs/PET thin films

In this work, silver nanowires (AgNWs) synthesized by the “Polyol” method were deposited on polyethylene terephthalate (PET) substrates in two layers using mechanical pressing, resulting in AgNWs/PET structures, and their physical properties were studied. It is shown that in this way it is possible to obtain AgNWs nanowires with a diameter of 50 $\pm$ 10 nm, a length of 15–20 $\mu$m and a density of 105–115 mg/m$^2$ and a thin AgNWs/PET film with a resistance of 2.4 $\Omega$/sq. The studied optical, electrical and structural characteristics of AgNWs/PET thin films confirm that they are a promising material as an electrode for flexible organic solar cells.
