鈣鈦礦太陽能電池具有成本便宜、製程簡單及高度發展性等等的優點受到科學家高度關注，而鈣鈦礦做為電池主動層材料具有一個很大的致命傷，就是很容易因為外在因素而產生降解，像是水氧或是高能紫外光等等的都會使鈣鈦礦降解，因此如何提升鈣鈦礦太陽能電池的光伏特性及穩定性就成為了目前的研究趨勢。
本篇論文選擇在整體元件的玻璃照光面塗佈具有發光降擋特性及強疏水性的CdZnSeS/ZnS 量子點來做為元件的保護層，並透過各種分析來證明其符合上述所提到的優勢，讓整體元件的光伏特性及穩定性得到顯著的提升。
實驗成功製作出具有濃度為5 mg/ml量子點保護層的鈣鈦礦太陽能電池，並具有了最佳的表現，功率轉換效率為17.71 %，短路電流密度為21.19 A/cm2，並且在穩定性方面具有了非常顯著的提升，其照光穩定性在持續照光一小時仍保持為初始效率的90 %，以及在大氣穩定性經過十天的存放後能保持為初始效率的70 %，代表CdZnSeS/ZnS 量子點對鈣鈦礦太陽能電池的穩定性具有優異的保護力，未來可以將其應用在對元件的封裝，使得鈣鈦礦太陽能電池能具有更長的壽命。

In the past decade, solar cells have received significant attention. Currently, most commercially available solar cells are silicon-based. However, due to their high cost and complex manufacturing process, research has shifted towards the development of other types of solar cells. Perovskite solar cells have become a major focus of development. However, perovskite materials are prone to degradation from ultraviolet (UV) light and moisture, presenting challenges that need to be addressed for the commercialization of perovskite solar cells.
In this study, CdZnSeS/ZnS quantum dots (QDs) were selected as a protective layer to absorb UV light incident on perovskite solar cells and emit visible light for absorption by the perovskite layer. This approach aims to address the rapid degradation caused by ultraviolet (UV) light in perovskite solar cells. Additionally, the hydrophobic properties of CdZnSeS/ZnS QDs help prevent water vapor attachment, greatly enhancing the stability of perovskite solar cells.
