在本研究中,我們試圖製備一具有良好具有低溫燒結性的二氧化鈦漿料。此二氧化鈦漿料可用於製備染料敏化太陽能電池光陽極。這裡的「低溫燒結」係指在低於150攝氏溫度下進行燒結,在這個溫度下,大多數用於染料敏化太陽能電池的軟性基材(例如ITO-PET)可以承受。 首先,利用已知配方的二氧化鈦漿料來進行剖析,建立了一種可以有效分析二氧化鈦漿料組成的方法。並用藉由這種方法,對市售的低溫燒結型二氧化鈦漿料進行分析。接著,從所獲得的分析資料與從文獻回顧提出的概念中,我們選擇了被稱為「化學燒結法」的製備方式,分別製備了兩種低溫燒結型二氧化鈦漿料:一種是噴塗型漿料,而另一種是網印型漿料。結果所獲得的光電轉換效率,分別為1.231 %與 2.163 % (於FTO玻璃)。
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.
