本論文研究的主題為並五苯/駢苯衍生物(pentacene/PTCDI-C13)太陽能電池的電場調制光譜。對樣品施加電場產生斯塔克效應(Stark effect)後,將得到調制光譜進行擬合,可得到各個主要結構隨著調制電壓和和外加直流壓,對於不同溫度的變化趨勢。施加交流調制電壓時,躍遷能量1.85 eV、1.97 eV的譜形結構由高斯一次和二次微分譜形所組成,2.12 eV和2.17 eV的譜形結構由高斯一次微分譜形所組成。在外加直流偏壓調制光譜的部份中,當直流偏壓達到反相臨界偏壓時,譜形會有所顛倒,而躍遷能量1.85 eV、1.97 eV和2.17 eV的譜形結構,主要由高斯一次微分函數的譜形所組成,2.56 eV的譜形結構由高斯一次和二次微分譜形所組成。藉由電場調制光譜的譜圖分析,即可得知樣品內部的光學躍遷機制和載子傳輸等訊息。
