本論文研究主題包含環保量子點製作與環保量子點於太陽能電池之應用，成功製作出三個種類環保量子點：碳量子點、奈米銅團簇與二硫化銀銦量子點，鑑定其光學物理性質；並分別以奈米銅團簇量子點及二硫化銀銦量子點製作染敏化太陽能電池，效率分別為0.012%與 0.042%；亦利用碳量子點製作太陽能電池色轉換層薄膜以搭配CIGS太陽能電池，並藉由光學分析探討此量子點薄膜對太陽能電池的影響。

In this thesis, we fabricated eco-friendly quantum dots (QDs) and then utilized them in solar cells. Carbon quantum dots (CDs), Cu nanoclusters (CuNCs) and AgInS2 (AIS) quantum dots was successfully synthesized along with the measurements of their photophysical properties. CuNCs and AIS were implemented in dye-sensitized solar cells, garnering photoelectric conversion efficiency of 0.012% and 0.042%, respectively. Luminescent down-shifting (LDS) layer for CIGS thin-film solar cell was realized by CDs. The repercussions of the quantum yield and scattering of the quantum dots LDS layers to CIGS solar cells efficiency was also studied.
