The most widely used transparent electrode material for optoelectronic devices is indium tin oxide (ITO) due to its low sheet resistance but, its high cost, stiffness, and lack of adhesion to organic and polymeric materials make it unsuitable for manufacturing flexible devices on plastic substrates. Therefore, new alternative ductile electrode materials must be developed and AgNW is one of those that meet the requirements. In this study, a simple and effective solution process method for manufacturing AgNWs-based sandwich type flexible transparent electrode is developed and presented. First, a PEDOT:PSS layer was applied to the PEN substrate and AgNWs were applied on it. Finally, to smooth out the rough surface of AgNWs, PEDOT:PSS with high conductivity was coated once again (PEDOT:PSS/AgNWs/PEDOT:PSS). This method was able to dramatically improve the surface roughness of AgNWs electrodes without significant reduction of conductivity. This selective multilayer sandwich type electrode showed a low sheet resistance of 22 Ω/sq, and the transmittance was measured at a maximum of 82%. A three-layer sandwich type electrode was used as an anode for a polymer solar cell (PSC). PSCs with the above electrodes showed similar performance to devices based on ITO anode.
