本論文的研究內容將會針對小面積反式結構鈣鈦礦太陽能電池元件進行開發，由於實驗室先前研究有機太陽能電池以開發小面積的圖形，本實驗將沿用相同的圖形來開發以鈣鈦礦材料為活性層的太陽能電池，為了將鈣鈦礦材料實現在大面積模組上，因此先從小面積開始研究材料本身的特性以及最佳薄膜的條件，達到高效率後以便未來中面積與大面積的開發。
主要所採用的元件結構為 ITO / ZnO / CsPbI2Br（鈣鈦礦）/ P3HT / MoO3/ Ag，改變製程條件來達到最佳效率，同時分析不同製程條件的鈣鈦礦薄膜的膜面狀態，並分別對鈣鈦礦活性層、電動傳輸層進行優化，以改善元件效率。
在本實驗中，會先嘗試不同製程條件，建立一套穩定且達到一定效率的製程，接著針對活性層轉速與膜厚、電洞傳輸層的濃度等條件作優化，藉由測量光電轉換效率來比較並找出最佳效率的條件。
而本實驗還會針對鈣鈦礦使用介面鈍化處理，使用有機胺鹽BAI進行表面鈍化以增加元件的穩定性，觀察整體效率與元件的壽命。

This study focuses on the development of small-area inverted structure perovskite solar cells. Building upon previous research in our laboratory on organic solar cells with small-area patterns, this experiment will utilize the same patterns to develop solar cells using perovskite materials as the active layer. To eventually apply perovskite materials to large-area modules, we begin by investigating the characteristics of the materials and the optimal thin film conditions on a small scale. Once high efficiency is achieved, the findings will facilitate the development of medium and large-area applications.
The primary device structure employed in this research is ITO/ZnO/CsPbI2Br (perovskite)/P3HT/MoO3/Ag. By altering the processing conditions, we aim to achieve the best efficiency. We will analyze the surface states of perovskite films produced under different conditions and optimize both the perovskite active layer and the hole transport layer to enhance device efficiency.
In this experiment, we will first attempt different processing conditions to establish a stable and efficient process. Subsequently, we will optimize parameters such as the spin-coating speed, the thickness of the active layer, and the concentration of the hole transport layer. The conditions yielding the highest efficiency will be identified through measurements of the power conversion efficiency.
Additionally, this study will apply interface passivation treatments to the perovskite layer using the BAI to enhance device stability. The overall efficiency and device lifespan will be observed to determine the effectiveness of this approach.
