碩士 === 正修科技大學 === 化工與材料工程研究所 === 100 === The thesis describes the process of Quinoxaline derivatives and these were applied to organic solar cells. The thermal properties of Quinoxaline derivatives were examined by TGA and DSC. The optical properties of these derivatives were investigated by UV and PL in this study. With regard to the organic solar cells, first and foremost, the structure was designed as ITO / CuPc (25nm)/C60(30nm)/BCP (5to 30nm)/Ag (100nm). Secondly, CuPc and C60 are the donor and acceptor materials respectively. The BCP is used as exciton blocking layer, changing the BCP thickness from 5 to 30nm. We may know that the highest efficiency of thickness would be 15nm based on the efficiency of components. Therefore, the suitable 15nm-thickness was selected as the structure of the Standard. After determining the structure of the Standard, put the Quinoxaline derivatives into the device that between exciton blocking layer (BCP) and Electrodes (Ag) as an electron transport layer. Finally, the components are further measured by photoelectric conversion efficiency, the external quantum efficiency (EQE), Ultraviolet-Visible spectrophotometer (UV-VIS), and the roughness of the surface measurement. The purpose of this study is to compare the differences between added Quinoxaline derivatives with its various components and the Standard.
