Silver nanowires (AgNWs) are synthesized using rapid synthesis polyol process by keeping polyvinylpyrrolidone (PVP): silver nitrate (AgNO₃) 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 AgNO₃ (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.

全解决方案的高度透明的银纳米线/ PEDOT：PSS光电导薄膜

通过保持聚乙烯吡咯烷酮（PVP）：硝酸银（AgNO ₃）的比例恒定，使用快速合成多元醇工艺合成银纳米线（AgNWs），并系统地研究了它们对AgNWs形成的影响。使用场发射扫描电子显微镜（FESEM），透射电子显微镜（TEM），X射线光电子能谱（XPS），UV-Vis光谱和能量色散X射线能谱（EDX）分析来分析合成的AgNW的形态学特性。典型的平均长度为5μm的AgNW在较高浓度的AgNO ₃中生长（0.08 M）。混合透明导电电极（TCE）是通过将优化的AgNWs与导电聚合物基体-聚（3,4-乙烯二氧噻吩）聚苯乙烯磺酸盐（PEDOT：PSS）混合并旋涂到玻璃基板上而制成的。与PEDOT：PSS TCE相比，在混合TCE的情况下，IR区域的透明度和电导率得到了显着改善。进行品质因数计算以评估制成的TCE的性能，并且混合膜的质量比PEDOT：PSS TCE的质量提高了5到7倍。
