利用溶膠-凝膠法製備之氧化鋅/鋁摻雜氧化鋅電子傳輸層改善倒置鈣鈦礦太陽能電池

本論文主要在研究鈣鈦礦太陽能電池中的電子傳輸層，我們使用溶膠-凝膠法製備氧化鋅作為鈣鈦礦太陽能電池中的電子傳輸層，接著進一步使用氧化鋅/鋁摻雜氧化鋅作為鈣鈦礦太陽能電池之電子傳輸層。藉由鋁摻雜氧化鋅薄膜的使用，鈣鈦礦太陽能電池的光電轉換效率PCE也由12.41% 提升至14.67%、開路電壓Voc 1.09V、短路電流密度Jsc 19.41mA/cm2、填充因子FF 68.99%。將鋁摻雜氧化鋅用於氧化鋅、鈣鈦礦主動層之間，這讓能階更匹配、鈣鈦礦主動層的載子更容易分離出來。我們成功使用氧化鋅/鋁摻雜氧化鋅電子傳輸層，改善鈣鈦礦太陽能電池元件表現。

In this study, the electron transport layers (ETLs) effect on perovskite solar cells was discussed. First, we used sol-gel process ZnO as ETLs in the perovskite solar cells, and then we used ZnO/Al-doped ZnO (AZO) as ETLs in the perovskite solar cells. The power conversion efficiency (PCE) of perovskite solar cells were increased from 12.41% to 14.67% with open-circuit voltage (Voc) of 1.09V, short-circuit current density (Jsc) of 19.41 mA/cm2, and fill factor (FF) of 68.99% by using the AZO thin film. Through using AZO layer in ZnO/CH3NH3PbI3, it can modify energy-level alignment and improve charge separation of CH3NH3PbI3 active layer. We have succeed in improving perovskite solar cells performance by using ZnO/AZO electron transport layers.
