The aim of this study is to attain an extensive insight on the performance mechanism that is associated with the formation of Cu nanostructures- polytetrafluoroethylene (PTFE) thin film. The work presented Cu nanostructures synthesised via microwave-assisted method at different Cu precursor concentrations to observe the influence of different average particle diameter distribution, [Formula: see text] of Cu nanostructures on the fabricated Cu nano thin film. The thin films of Cu nanostructures with a layer of PTFE were fabricated using the Meyer rod coating method. Evaluating the effect of Cu nanostructures at different [Formula: see text] with overcoated PTFE layer showed that the resistance of fabricated thin film coated with PTFE is not significantly different from that of the uncoated thin film. The results implicate the influence of the PTFE layer towards the output performance, which can maintain a stable and constant resistance over time without affecting the original properties of pure Cu nanostructures, although some of the Cu nanostructures seep into the layer of PTFE. The novelty of this study lies in the effect of the intrinsic interaction between the layer of Cu nanostructure and PTFE, which modulate the performance, especially in photovoltaic cell application.
本研究的目的是深入了解与铜纳米结构-聚四氟乙烯（PTFE）薄膜形成相关的性能机制。这项工作展示了通过微波辅助方法在不同铜前驱体浓度下合成的铜纳米结构，以观察不同平均粒径分布的铜纳米结构的[公式：见原文]对制备的铜纳米薄膜的影响。采用迈耶棒涂布法制备了带有一层聚四氟乙烯的铜纳米结构薄膜。评估不同[公式：见原文]的铜纳米结构与涂覆的聚四氟乙烯层的效果表明，涂覆有聚四氟乙烯的制备薄膜的电阻与未涂覆薄膜的电阻没有显著差异。结果表明聚四氟乙烯层对输出性能有影响，尽管一些铜纳米结构渗入聚四氟乙烯层，但它可以随时间保持稳定且恒定的电阻，而不影响纯铜纳米结构的原始性能。本研究的新颖之处在于铜纳米结构层与聚四氟乙烯之间的内在相互作用的影响，这种相互作用调节了性能，特别是在光伏电池应用中。
