染料敏化太陽能電池（DSSCs）是一種新型的太陽能電池，其光陽極通常使用二氧化鈦（TiO2）薄膜作為電子傳輸劑，以及染料分子吸收太陽光譜的能量，將其轉換為電能。而富勒烯是一種由碳原子組成的球形分子，具有良好的電子傳輸性能、高度的化學穩定性以及廣泛的應用前景，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。
本研究中透過分別添加不同濃度的富勒烯及奈米銀線於二氧化鈦，以網印法製備成染料敏化太陽能電池，並探討各濃度的富勒烯及奈米銀線對染敏電池的影響。將製備出的染敏電池進行量測與比較，分析純二氧化鈦、摻雜富勒烯、富勒烯/奈米銀線染敏電池之特性。
研究結果表明，摻雜了富勒烯/奈米銀線的二氧化鈦複合薄膜染敏電池相較於純二氧化鈦所製成的薄膜染敏電池，其短路電流(Jsc)由13.48 mA/cm2上升至14.10 mA/cm2，光電轉換效率從5.81%上升至6.22%，整體效率提升了7.05%

Dye-sensitized solar cells (DSSCs) are a new type of solar cell that typically use a titanium dioxide (TiO2) thin film as the electron transport agent in the photoanode, along with dye molecules that absorb energy from the solar spectrum and convert it into electricity. Fullerene is a spherical molecule composed of carbon atoms that has good electron transport properties, high chemical stability, and wide-ranging potential applications. Nano silver wires are suitable for use as composite materials in the production of photoanodes due to their low resistance, high conductivity, and surface plasmon resonance properties, and may help to increase the efficiency of dye-sensitized solar cells.
In this study, different concentrations of fullerene and silver nanowires were added to titanium dioxide using screen printing to fabricate dye-sensitized solar cells (DSSCs). The effects of these additives on the performance of DSSCs were investigated. The prepared DSSCs were measured and compared, and the characteristics of pure titanium dioxide, fullerene-doped, and fullerene/silver nanowire-doped DSSCs were analyzed.
The results showed that the composite film DSSCs with fullerene/silver nanowire doping exhibited improved performance compared to DSSCs made with pure titanium dioxide. The short-circuit current density (Jsc) increased from 13.48 mA/cm2 to 14.10 mA/cm2, and the photoelectric conversion efficiency increased from 5.81% to 6.22%. The overall efficiency improved by 7.05%.
