碩士 === 國立臺北科技大學 === 有機高分子研究所 === 101 === In this study, a new process method has been developed to prepare a low-temperature sintering titanium dioxide paste to make photoelectrodes for the application of dye sensitized solar cells (DSSCs). Herein, the definition of “low-temperature sintering” is referred to the sintering temperature below 150 oC.The low temperature samples can be used for the flexible substrates (e.g. ITO-PET) in DSSCs, which can withstand within this temeperature range. First, a useful approach for analyzing the home-made TiO2 paste has been established in order to get the basic information of commercial low-temperature TiO2 paste. The “chemical sintering” method was chosen from literatures review to prepare a low-temperature sintering titanium dioxide paste and it has been utilized by two types of coating method such as spray-coating and screen-printing processes respectively. The obtained optimum efficiency in DSSCs for spray-coating and screen printing method based photoelectrodes were 1.231 % and 2.163 %, respectively.
