本論文主要的研究目標是增強二維鈣鈦礦材料的橫向電荷傳輸能力，以提升其光伏性能。為了達成這一目標，我們通過添加能夠導電的分子來改善鈣鈦礦的光伏特性。在篩選了幾個分子後，我們針對顯示出最好性能的Benzotriazole (BTZ)進行研究，並探討其對鈣鈦礦性能的影響。我們的研究結果顯示，添加BTZ分子能有效提升鈣鈦礦材料的吸光度。進一步的量子效率測試證實了BTZ的添加不僅增強了吸光度，同時也顯著提升了材料的電性能。X射線繞射分析確認了BTZ的存在能有效提升材料的結晶度。通過四點探針和霍爾量測儀的驗證，我們觀察到BTZ的添加有助於促進載流子在鈣鈦礦中的橫向遷移，進而改善載子的傳輸特性。這兩點結果表明，添加BTZ在二維鈣鈦礦中有效提升了結晶度，同時也顯著改善了光伏材料的電荷傳輸性能。接著當我們進行二次離子質譜儀的縱向分析時，我們發現在適量的BTZ添加下，薄膜表面積累了一些BTZ分子。這些分子似乎對鈣鈦礦薄膜的性能產生了正面的影響。當含有少量的BTZ於薄膜表面時，有助於鈣鈦礦層與PC61BM之間建立更緊密的接觸，進而有效地降低電阻。綜上所述，本研究的結果顯示，添加BTZ分子能顯著增強二維鈣鈦礦薄膜的光伏性能。因此，未來的研究可進一步探索其他分子的應用，並深入瞭解苯環的反應機制，從而推動太陽能技術的發展。

The main objective of this thesis is to enhance the lateral charge transport capability of two-dimensional perovskite materials to improve their photovoltaic performance. To achieve this goal, we introduced conductive molecules to enhance the photovoltaic properties of perovskite. After screening several molecules, we focused on investigating the impact of Benzotriazole (BTZ), which exhibited the best performance, on perovskite properties. Our research results demonstrated that the addition of BTZ molecules effectively increased the light absorption of perovskite materials. Further quantum efficiency measurements confirmed that BTZ not only enhanced light absorption but also significantly improved the electrical properties of the material.
Through confirmation with four-point probe and Hall measurement equipment, we observed that the addition of BTZ facilitated the lateral migration of charge carriers in the perovskite, thereby improving charge transport properties. Moreover, during SIMS analysis, we discovered that an appropriate amount of BTZ accumulation on the surface of the thin film positively affected the perovskite film's performance.
In conclusion, our research results demonstrate that the addition of BTZ molecules significantly enhances the photovoltaic performance of two-dimensional perovskite thin films. Therefore, future research can further explore the application of other molecules and investigate the reaction mechanism of the benzene ring to advance solar technology.
