Silver nanowires (AgNWs) have been considered as promising materials for fabrication of transparent conducting electrodes (TCEs) due to their suitable optical and electrical conductivity. The current work investigates the effects of the synthesis parameters on the physical and morphological properties of AgNWs-based TCEs and the photovoltaic performances of ITO-free AgNWs-electrode based flexible polymer solar cells (FPSCs). AgNWs were prepared using two different polyol-based methods including modified polyol (MP) and Sigma polyol (SP) processes. These methods differed in the type of applied seed, ratios of PVP/AgNO₃ and AgNO₃/seed, AgNO₃ injection rate and temperature. The reflux condition was used as a novel effective parameter in the MP method. Results showed that MP-AgNWs possessed higher aspect ratio compared to those obtained from the SP process. AgNWs-based TCEs were prepared using spin coating method. The injection volume and the thickness of AgNWs-electrodes were altered to find the optimized electrodes in terms of sheet resistance (R_s) and transparency. The optimized MP-AgNWs and SP-AgNWs electrodes based on H-FoM calculations showed different R_s of 11.3 and 99.3 Ω.sq⁻¹ and transparency of 92.8% and 90.4%, respectively. These electrodes were integrated as the photo-anode in the construction of ITO-free FPSCs. The prepared FPSCs based on the optimized MP-AgNWs electrodes showed PCE of 3.18% which was about 28% higher than that obtained using the best SP-AgNWs electrodes. The photovoltaic performance of MP-AgNWs electrode based FPSC was found to be very close to those of ITO-based reference cell prepared using similar conditions. However, the PCE of these FPSCs was about 18% lower which can be improved by altering the synthesis parameters.

银纳米线（AgNW）由于具有合适的光学和导电性，因此被认为是制造透明导电电极（TCE）的有前途的材料。当前的工作研究合成参数对基于AgNWs的TCE的物理和形态特性以及不含ITO的AgNWs电极的柔性聚合物太阳能电池（FPSC）的光伏性能的影响。使用两种不同的基于多元醇的方法制备AgNW，包括改性多元醇（MP）和Sigma多元醇（SP）工艺。这些方法在应用种子的类型不同，PVP的比率/的AgNO ₃和的AgNO ₃ /种子，硝酸银₃注射速度和温度。在MP法中，回流条件被用作新的有效参数。结果表明，MP-AgNWs的长宽比比从SP工艺获得的高。使用旋涂法制备了基于AgNWs的TCE。改变AgNWs电极的注入量和厚度，以在薄层电阻（R _s）和透明度方面找到最优化的电极。基于H-FoM计算的优化MP-AgNWs和SP-AgNWs电极显示不同的R _s为11.3和99.3Ω.sq ^-1透明度分别为92.8％和90.4％。这些电极被集成为无ITO FPSC的光阳极。基于优化的MP-AgNWs电极制备的FPSC的PCE为3.18％，比使用最佳SP-AgNWs电极获得的PCE高约28％。发现基于MP-AgNWs电极的FPSC的光伏性能与使用类似条件制备的基于ITO的参比电池的光伏性能非常接近。但是，这些FPSC的PCE降低了约18％，这可以通过更改合成参数来改善。
