能源一直是現代文明社會的一個重要課題，石油在過去1~2 百年來皆是非常重要的能源來源。但中東的幾個主要的產油國家一直因為宗教問題而紛紛擾擾，任何一個不可預期的事件都可能延申至此區域的動盪不安，而導致影響石油供應的穩定性，這對於我國這種 98%能源需仰賴輸入的國家，更需要有未雨綢謀的能源策略，使得太陽能光電產業成為21 世紀最重要的明星產業之一。能將光能轉換成太陽能的電池種類不少，其中之一為Gr?tzel 在1991 年於Nature 上發表的染料敏化太陽電池，此類電池因製造簡單、材料多元、且能達到10%的能源轉換率，引起學術與業界的注意，世界各國都積極投入研究與開發。Gr?tzel 的染料敏化太陽電池使用液態溶液做為電解質，此方法的缺點是封裝較不易且穩定性較差，這對應用在輕薄短小的電子元件上是個障礙，為修飾這個缺點，我們計劃使用高分子電解質來取代溶液態電解質，以製造使用性更方便之染料敏化太陽電池。計劃中以PVDF-HFP 共聚物為主體，配合適當的加工與第二種高分子的摻雜，形成具高吸附性的孔洞高分子載體，用其吸附電解液可做成類似固態的電解質以應用在太陽能電池上。 Energy is an important issue of the modern society. Petroleum is the major energy source in the past 1 to 2 hundred years. The energy supplied countries have a lot of problem inside and their political is unstable, any small unexpected event may cause the war between them. The supply of the petroleum will be a problem. 98% of petroleum in Taiwan was supplied by the foreign countries, how to find a possible alternative energy is very important. Solar energy is a clean and the most abundant renewable energy. There are several types of cells can be used to convert light to electricity. Amongst them, a new generation of solar cell called Dye-Sensitized Solar Cell (DSC) has developed in 1991. DSC has the advantage of easy fabrication, versatile materials can be used and reasonable photo conversion efficiency. However, the problem of the DSC is the poor stability related to the liquid electrolyte (I-/I2 in CH3CN&C4H9CN). The objective of this proposal is to search for high conducting solid electrolyte to be used in DSC. We use two approaches to prepare solid electrolyte. One is to prepare true dry solid electrolyte with high hole mobility. The second way is preparing PVdF based porous electrolytes. PVdF based polymer electrolytes are not true dry electrolyte since it contains lots of incorporated solvent. However, the solvent was trapped inside the porous polymer matrix. Therefore, the leakage problem will be solved and the damage of the cathode will be reduced since solvent and electrode has a smaller contact area. 研究期間：9601 ~ 9612
