碩士 === 義守大學 === 材料科學與工程學系碩士班 === 99 === Organic solar cells have great attractive for photoelectron region , and have advantage over other forms of solar cells , because they offer low-cost、 light weight、 easily processing、 design of freedom and can be fabrication into flexible solar cell to achieve the absorption of sunlight . Conjugated polymers have been attracting much attention in recent years due to their potential applications in optoelectronic and photovoltaic devices. With advantage of soluble in general organic solvents and easily processing, design of freedom, process cheaper, lighter and lower cost, crack-resistant features. It have potential applications in prepare of optical-electronic devices, thin-film transistors, and photovoltaic devices . In this study, conjugated conductive polymer Poly (9,9-n-dioctylfluorene- alt-bithiophene), (F8T2) poly (3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61 -Butyric acid met-hyl Ester (PCBM) being blended. The project expected to achieve：(a) Discuss the effect of F8T2 and P3HT after blending with PCBM , and do the different time through the thermal erasing procedure, its surface morphology and average roughness、microstructure and optical properties. (b) Find the optimization of parameters through the thermal erasing procedure. Discover the surface morphology, optical properties, molecular package, microstructure and phase separation of blending systems by different treatment conditions. (c) Finally, preparation of solar cell devices and discuss their optical-electronic properties. The final objective is to be of conjugated polymer blending system in depth relative the phase stability and solar cell devices of power conversion efficiency. That can help for development of solar cell devices for the future.
