本研究主要目的是利用微波合成法取代傳統水熱法製備二氧化錫並應用於染料
敏化太陽能電池（Dye-sensitized Solar Cells）以及量子點染料敏化太陽能電池（Quantum Dots on Dye-Sensitized Solar Cell）研究水解及離子液體系統合成二氧化錫。本研究一開始選擇以水為溶劑合成SnO2及利用離子液體幫助我們合成二氧化錫，選擇適合當做光電極材料的二氧化錫，再研究不同PH值與Particle Size的關係，以了解我們二氧化錫在酒精中分散情形，接著配置成二氧化錫醬料，利用網印法將二氧化錫製作成光電極搭配上SQ2染料組裝成液態染料敏化太陽能電池使其最高轉換效率可達到0.502%、組裝成固態染料敏化太陽能電池使其最高轉換效率可達到0.183%，雖然與二氧化鈦相比效率無法超過，但製程時間可大幅地縮短；搭配上量子點Ag2S在量子點固態染料敏化太陽能電池元件上，其短路電流密度達到0.669mA/cm2超越了二氧化鈦的短路電流密度，而轉換效率達到0.028%超越了二氧化鈦的光電極。

The main purposes of this study are replacing conventional hydro-thermal method by microwave heating and using water or ionic liquid solvent as reaction medium to rapidly synthesize SnO2. In the first part, we use water as the solvent and (Tin(IV) chloride anhydrous, SnCl4) as the precursor for hydrolysis. The solution is subsequently heated with microwave for crystal growth. The reaction time could be shortened into few minutes.
Then we chose suitable particle size to prepare SnO2 paste on the power conversion efficiency of Dye-Sensitized Solar Cells(DSCs) and Quantum dots Dye-Sensitized Solar Cells(QDSCs). To realize the relationship between PH value and particle size can help us to understand tin oxide dispersed in alcohol, then preparing tin oxide paste.
Using the screen printing method will be made into tin dioxide photoelectrode, assembled into a liquid dye sensitized solar cell with SQ2 dye, so that the maximum conversion efficiency can reach 0.502%, in solid-state dye-sensitized solar cells so that the maximum conversion efficiency can reach 0.183%. With Ag2S quantum dots in a quantum dot solid-state dye-sensitized solar cell, its short circuit current density of tin dioxide photoelectrode over the short circuit current density of titanium dioxide photoelectrode. Moreover, the conversion efficiency reach to 0.028% and also over titanium oxide photoelectrode.
