本研究主要目的是利用物理摻雜的方式，將有機駢苯小分子摻入鈣鈦礦前驅液，並以一步驟旋塗法製成鈣鈦礦太陽能電池，期望藉由此有機駢苯小分子的能量轉移來提升鈣鈦礦的光電流，進而提升光電轉換效率。本實驗主要分為兩個部分，第一部分主要是在以溶劑工程法一步驟旋塗製成鈣鈦礦太陽能電池的研究與探討，透過不同的延遲時間(無滴入、3秒、5秒、7秒)滴入氯苯來探討鈣鈦礦薄膜品質，藉由紫外光-可見光光譜吸收(UV-Vis)分析、X光繞射(XRD)分析、掃描式電子顯微鏡(SEM)分析，並得到延遲時間為5秒時所製作出來的鈣鈦礦薄膜具有最優異的性質，並且此薄膜能擁有最佳的太陽能電池元件表現。而第二部分是摻雜有機駢苯衍生物(PTCDI-C7與PTCDI-C8)於鈣鈦礦前驅液，以第一部分之最佳參數及方法製成鈣鈦礦太陽能電池，並以太陽能模擬器量測其光電轉換效率，測得摻雜PTCDI-C7與PTCDI-C8可以使鈣鈦礦的效率分別增加14 %及33 %，最後根據外部量子效率量測儀測結果，證實鈣鈦礦太陽電池效率的增加主要是來自光電流的上升。

In this study, we physically doped the PTCDI molecules in the perovskite precursor, and fabricated the perovskite solar cells with one-step spin coating and the solvent engineering method. We expected that the PTCDI molecules could have an energy transfer effect in order to increase the current of the perovskite solar cells. There are two parts in this study. In the first, we studied fabricating the perovskite solar cells with one-step spin coating and the solvent engineering method. We dripped the chlorobenzene with different delay times (0s, 3s, 5s, 7s) during the perovskite precursor spinning. Through the UV-Vis spectrum, XRD, SEM, we found the best delay time of the perovskite thin films was 5 seconds. In the second part, we doped the PTCDI-C7 and PTCDI-C8 into the perovskite precursor, and fabricated the perovskite solar cells with the best parameters and method from the first part. The doped devices showed 14 % and 33 % increases in efficiency for PTCDI-C7 and PTCDI-C8 respectively. It was proved that the increasing efficiency was due to the increase in the photovoltaic current based on the measurement of external quantum efficiency (EQE).
