项目标书摘要：PEDOT:PSS/石墨烯复合薄膜为一种新颖电极材料，其可见光平均穿透率可高於80%,电能转换效率高於纯PEDOT:PSS材料。另外，此薄膜成分不含铟、金和银等贵金属元素，所以这种材料成本比一般含贵金属元素之透明导电氧化物成本低，可广泛应用於太阳能电池、发光二极体、燃料电池和软性电子产品。另外一方面，传统薄膜电极图案化主要采用半导体湿式蚀刻制程，该制程需使用有机化学溶液、昂贵设备和多道制程。因此，本计划将自行建置奈秒脉冲Nd:YVO4雷射加工系统，搭配X-Y轴振镜扫描和影像拼接技术，应用於PEDOT:PSS/石墨烯复合薄膜沈积在可挠性塑胶和玻璃基板之大面积电极微成型与雷射加工参数交互作用探讨。藉由雷射乾蚀刻制程简化传统湿蚀刻制程、减少对化学蚀刻溶液使用和提升薄膜移除效率。PEDOT:PSS/石墨烯复合薄膜剥蚀机制将采雷射加工参数调控，包括雷射脉冲能量、雷射脉冲重复频率和振镜扫描速度，探讨材料移除之雷射能量剥蚀阀值。雷射脉冲重复频率和振镜扫描速度可用於计算光斑重叠率和讨论电极微成型之边缘品质。此外，雷射微成型後薄膜电极结构将使用三维共焦显微镜、扫瞄式电子显微镜、奈米压痕仪、分光光谱仪与四点探针等量测仪器，分析其表面机械性质和光电特性。

Application Abstract: PEDOT:PSS/graphene composite films are a novel electrode material that the visible light transparency is averagely large than 80%.Moreover,the photoelectron transfer efficiency of PEDOT:PSS/graphene films is large than the pure PEDOT:PSS material.Because of the PEDOT:PSS/graphene composite films containing no noble metal elements such as indium(In),gold(Au)and silver(Ag),the cost of this composite material is in general less than other transparent conductive oxides(TCOs).Due to their strong price competition,the PEDOT:PSS/graphene films are accepted to apply as the conductive material for the thin film solar cells,light-emitting diodes,fuel cells,and other flexible electronics products.On the other hand,the traditional electrode patterning of thin films involves photolithography processes.The photolithography equipment is expensive and requires environment harmful chemicals and complicated steps in the fabrication process.Consequently,this project aims to establish a nanosecond pulsed Nd:YVO4 laser processing system combined with a X-Y axis scanner and image stitching technologies.The developed equipment will use for the large-area electrode microstructuring and investigate the interaction between laser beams and PEDOT:PSS/graphene films deposited on plastic and glass substrates,respectively.This novel process can reduce the fabrication steps and the quantity of chemical solutions and can improve the removal efficiency of PEDOT:PSS/graphene films.The processing parameters including the laser pulse energy,the pulse repetition frequency,and the scanning speed of galvanometers will adjust to ablate out the PEDOT:PSS/graphene films that can calculate the ablation threshold.The laser pulse repetition frequency and the scanning speed of galvanometers will apply to calculate the overlapping rate of laser spots and to discuss the microstructuring quality.In addition,the mechanical and optoelectric properties of composite films deposited on different substrates after laser microstructuring will measure by a three-dimensional(3D)confocal laser scanning microscope,a scanning electron microscope(SEM),a nanoindenter,a spectrophotometer,and a four-point probe instrument.
