　　染料敏化太陽能電池(DSSCs)製作過程中含有奈米科技及有機物，屬於第三世代多晶矽太陽能電池，因製造成本低廉、製成容易且具備可饒性等優點，因此被視為極具發展潛力的太陽能電池。奈米銀線因其低電阻、高導電性及表面電漿共振等特性，適合做為製作光陽極的複合材料，有望提升染料敏化太陽能電池的效率。
　　本次研究以不同濃度的奈米銀線及二氧化鈦複合漿料製備光陽極複合層，製成染料敏化太陽能電池，並比較以不同濃度奈米銀線製備的電池特性。之後再將奈米銀線與二氧化鈦複合層和純二氧化鈦漿料以刮刀法交互堆疊於Indium tin oxide (ITO)玻璃基板上，再以高溫爐進行退火處理，完成電極敏化後利用三明治堆疊法完成染料敏化太陽能電池之製作，並比較不同堆疊方式之光陽極製成的染敏電池特性。
　　研究結果顯示，由0.05wt%奈米銀線和二氧化鈦複合光陽極與純二氧化鈦所製成的光陽極相比，其短路電流(Jsc)由5.32提升至7.53mA/cm2，光電轉換效率從3.08%提升至3.5%，效率約提升0.5%；而TST的堆疊方式其短路電流(Jsc)為8.44mA/cm2，光電轉換效率達到4.38%，與純二氧化鈦製成的光陽極相比，效率約提升了1.3%。

In this study, the photoanode composite layer was prepared with different concentrations of silver-nanowires and titanium dioxide composite paste to make dye-sensitized solar cells, and the characteristics of the cells prepared with different concentrations of silver-nanowires were compared. Then, the silver-nanowire the titanium dioxide composite layer, and the pure titanium dioxide paste are alternately stacked on the Indium tin oxide (ITO) glass substrate by the doctor blade method, and then annealed in a high-temperature furnace, and the electrode sensitization is completed by the sandwich stacking method. Fabrication of dye-sensitized solar cells, and comparison of the characteristics of dye-sensitized cells made of photoanode stacked in different ways.
The research results show that the short-circuit current (Jsc) increased from 5.32 to 7.53mA/cm2, and the photoelectric conversion efficiency increased from 3.08% compared with the photoanode made of pure titanium dioxide. It is increased to 3.5%, and the efficiency is increased by about 0.5%; while the short-circuit current (Jsc) of the TST stacking method is 8.44mA/cm2, and the photoelectric conversion efficiency reaches 4.38%. Compared with the photoanode made of pure titanium dioxide, the efficiency is improved by about 1.3%.
