本論文研究使用的有機-無機鈣鈦礦太陽能電池為標準P-I-N結構
(ITO/PEDOT：PSS-AI4083/Bromide or Iodine Perovskite/PCBM(C60)/Al)，鈣鈦礦層製程方式為一步法旋塗溶液加上氯仿(chloroform)洗滌表面使表面平坦。
第一部分為改變鉛鹵鈣鈦礦中不同鹵元素(溴和碘)的比例，達到不同的電性以及吸收光波長範圍的改變，希望能以人為可控的製作方式，將吸收波長範圍不同的鈣鈦礦太陽能電池應用於匹配的環境以達到較有效的吸收。
第二部分為測試鈣鈦礦中鹵素為溴和碘，分別接觸氨氣後的電性影響，因想突破一般鈣鈦礦方面的研究多半與太陽能電池有關，本研究將鈣鈦礦材料製作成簡易的氣體感測器，進行不同鈣鈦礦材料對於氨氣的反應，將為鈣鈦礦開啟新的應用領域。
第三部分為嘗試在電子傳輸層(PCBM)及導電金屬(Al)的陰極端加入介面層氟化鋰(LiF)，使PCBM層與金屬鋁層的能階更加匹配，以提升填充因子(FF)進一步提升太陽能電池發光效率，並追蹤介面層對於電池壽命造成的影響。

The organic-inorganic perovskite solar cells used standard P-I-N structure
(ITO/PEDOT：PSS-AI4083/Bromide or Iodine Perovskite/PCBM(C60)/Al) in this thesis,
The fabrication of perovskite layer is single-step liquid spin process and then rinse chloroform for the flat surfaces.
The first part is changing the proportion of different halogen elements (bromine and iodine) in lead-halogen perovskites to make electrical and light wavelength absorption range different. We wish applied in matched environment to achieve more effective absorption with absorption wavelength artificially controllable.
The second part test the response with ammonia gas of halogen on bromine and iodine in perovskite. Because general perovskite researches are mostly related to solar cells, the different perovskite materials made into a simple gas sensor for the reaction of ammonia gas. We hope to open up new applications for perovskites.
The third part try to add lithium fluoride (LiF) at the cathode between the electron transport layer (PCBM) and conductive metal (Al). It can let energy level more matched at the positive structure perovskite solar cell cathode, further increasing the fill factor (FF) and efficiency and tracking the battery lifetime.
