Silver nanowires (AgNWs) are synthesized using rapid synthesis polyol process by keeping polyvinylpyrrolidone (PVP): silver nitrate (AgNO 3 ) ratio constant and their effect on the formation of AgNWs is systematically investigated. Morphological properties of synthesised AgNWs are analysed using field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), X‐ray photo‐electron spectroscopy (XPS), UV‐Vis spectroscopy and energy dispersive X‐ray spectroscopy (EDX) analysis. AgNWs with typical average length of 5 μm are grown at higher concentration of AgNO 3 (0.08 M). A hybrid transparent conducting electrode (TCE) is fabricated by mixing optimized AgNWs in conducting polymer matrix‐poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and spin coated on to glass substrate. A significant improvement in the transparency in IR region and conductivity is observed in the case of hybrid TCE as compared with PEDOT:PSS TCE. Figure of merit calculations are carried out to evaluate the performance of the fabricated TCEs and the quality of the hybrid film is improved by 5 to 7 times more than that of PEDOT: PSS TCE.
