面臨能源發展危機，開發新一代高效、且可持續利用的能源一直是重要議題之一；然而，近年來混合鹵素鈣鈦礦材料因具有高的光電轉換效率，以及各種優異的光學特性，在應用端以及學術界中引起了廣泛的關注，並被視為是潛在的解決方案之一。
本論文嘗試透過改變鈣鈦礦中相異鹵素比例來實現材料帶隙的主動可調控性，並結合疏水性絕緣層以提升材料於大氣環境下的穩定性，嘗試實現一種光譜範圍寬、波長可調控、且穩定性高的材料。實驗中，透過不同間距( 50 μm、400 μm )的金屬電極於材料之上，成功使材料的輸出波長隨偏壓提升而有藍移的現象；另外，透過添加聚苯乙烯(Polystyrene, PS)作為保護層，也成功使材料在大氣環境下維持良好的光學特性以及離子遷移現象達3三天以上。儘管將PS覆蓋於金屬電極之上時，並無隨偏壓增加產生波峰偏移之現象，本研究仍成功利用主動電控方式來調變有機混合鹵素鈣鈦礦的輸出波長，並且經過絕緣層的添加提升材料的穩定性。
由結果證明，未來可以嘗試將利用偏壓調整結合，並應用於雷射元件中的增益介質，達到一個能長期穩定使用，並可透過電控使其擁有多個輸出波長的雷射元件結構；也期望透過鈣鈦礦材料的簡易製程、高轉換效率特性，結合低成本的製程手法，改善傳統半導體產業中磊晶製程所不可避免的傳統能源消耗，發展新一代的能源，也期望此材料在未來於光電領域中能有更多元、且永續的發展。

In recent years, the development of efficient and sustainable energy sources stands as an important issue in today's world. Due to the remarkable photon-to-electron conversion efficiency (IPCE) and a range of exceptional optical properties, Mixed Halide Perovskite (MHP) have garnered extensive attention both in practical application and the academic fields, positioning MHP as a potential solution.
Our research dedicates to achieve the active tunability of the material band gap within MHP by altering the ratio of two different of halides and applying a bias. Furthermore, we integrate the hydrophobic insulating layer (Polystyrene, PS) with MHP to enhance material stability in normal environment conditions. Then, we measure MHP through PL spectrum under the continuous-wave laser. We successfully enhance material stability in normal environment conditions for more than 3 days, and control the wavelength through the applying bias.
This result shows that the material properties of perovskite, including reusability and high efficiency when combined with a low-cost manufacturing process, have the potential to address the substantial energy consumption issues prevalent in traditional laser component fabrication.
