摘要:	石化能在大量開採及過度消耗之下已日益枯竭，加上CO2排放量增加，地球暖化所造成的環境變遷，使人類意識到使用有機能源可能造成的後遺症，太陽能便成為無污染的替代能源之一。一種在1991年由Gr?tzel與O’Regan 提出的所謂的料敏化太陽能電池（Dye-Sensitized Solar Cell (DSC)，引起眾多的注意。但DSC使用液態電解質，因而使電池壽命不長且無法做成各式各樣的薄形電池限制其發展的空間，因此本計畫的主要目的是尋求固態或類固態的電解質來取代DSC電池中所用的液態電解質（I-/I2 in CH3CN &C4H9CN）我們所使用的策略有兩種：第一是合成具平面結構之有機共軛分子；第二種是合成含小孔洞之高孔隙度高子分載體做為液態電解質得吸附體，此類外表類似固態電解質但事實內部含多量之溶劑的類膠態電解質，曾成功的使用於鋰離子電池中。類膠態電解質的特色是其內含高量之溶劑，因此有好的離子導電度，但溶劑緊緊的被高分子鎖住，除了可避免漏液外也因溶劑緊緊的被高分子鎖住，除了可避免漏液外也因此與陰極的接觸面少腐蝕電極的機率也減小，就可增加電池的壽命。 The air pollution, due to the combustion of petroleum and coal caused the tremendously change of the weather which may eventually damage the life in this earth, including human being. One of the solutions for these problems is the renewable energy. Sun energy is the most abundant amongst the renewable energy. A new generation of solar cell called Dye-Sensitized Solar Cell (DSC) has developed. 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. Solid electrolytes have received considerable attention, because of their potential applications in solid-state batteries, electrochromic devices. The use of polymer electrolytes make batteries safer, lighter, and more flexible in shape. We use two approaches to prepare solid electrolyte. One is to prepare true dry solid electrolyte with high hole mobility, small conjugated molecules or ordered conjugated oligomer will be good candidates. 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 polymer matrix. Therefore, the leakage problem will be solved and the damage of the cathode will be reduced since solvent and electrode has a small contact area. 研究期間：9501 ~ 9512
