我們將利用高真空蒸鍍系統，在透明的導電陽極-氧化錫銦玻璃基板上成長有機薄膜與金屬陰極，進而完成p-i-n有機太陽電池之制作。在研究過程中，我們將利用多層結構的方法來完成有機太陽電池元件的研製，其完整結構為透明陽極/N型材料層/I層主動層/P型材料層/金屬陰極。而我們將改變不同有機材料與不同有機材料層厚度來進行元件光電特性的探討。
緊接著，我們將有系統地探討不同材料對有機太陽電池光電特性的影響。經我們研究證實，最佳化的有機太陽電池有著最佳的轉換效率表現，其原因推測可能為不同材料之深層缺陷(DLTS)表現將會影響太陽電池的轉換效率，除此之外，材料對於太陽光源的吸收程度，也在吸收頻譜的表現上呈現出來，影響了太陽電池元件的轉換效率。

The influence of the p-type layer on the performance of deposited 3,4,9,10-perylene-tetracarboxylic dianhydride (PTCDA) based on organic p-i-n solar cells is investigated. Two different p-type materials were used: zinc phthalocyanine (ZnPc) and amine 4,4’, 4’’-tris{N,(3-methylphenyl)-N-phenylamino}-triphenylamine (m-MTDATA). It could be significant further improvements in power conversion efficiency by using the suitable p-type layer materials. Evidences showed that ZnPc is an apropos p-type material with match energy level. In addition, the broader spectral coverage of ZnPc is another key factor contributing to the higher photocurrent. It also possesses a shallow bulk trap level, providing more detrapping holes form the bulk trap states to highest occupied molecular orbital states for transporting in ZnPc. It is suggested that these are the main contributing factors to the superior photocurrent and high power conversion efficiency.
