本研究是以電化學(循環伏安法)聚合方式合成聚苯胺薄膜於ITO陽極基板上，將其應用在高分子有機太陽能電池當作電洞傳輸層，其元件結構ITO(150nm)/PANI(50nm)/P3HT:PCBM(100nm)/Al(200nm)，探討調配不同的苯胺單體濃度所聚合而成的聚苯胺薄膜其表面形態、導電度、透光度等等，進而對元件效率的影響並與傳統電洞傳輸層PEDOT : PSS做比較。
在本研究中吾人對聚苯胺薄膜做了一系列材料特性分析，發現不同單體濃度所聚合而成的聚苯胺薄膜，其吸收光譜在450 nm~650 nm波段中(主動層的主要吸收波段)，穿透度至少都達80%以上，且導電度高達0.6 S/cm，擁有如此良好的光電特性，故可知聚苯胺薄膜具有作為電洞傳輸層的基本能力。而PANI薄膜的表面形態，經由本研究可知，可藉由調配不同的單體濃度使PANI薄膜的表面型態有所改變。
在元件效率表現探討上，發現元件效率主要會受到PANI表面形態的改變而有所影響，相較於其他濃度參數，在苯胺單體濃度0.3M參數下聚合PANI薄膜，擁有最適當的表面形態，其元件在本研究中有最高的功率轉換效率，可達1.76%。

This research is to synthesize PANI (polyaniline) thin film for polymer organic solar cells as a hole transport layer on the top of ITO substrate by using electrochemical (cyclic voltammetry) method. The device structure is ITO (150 nm) / PANI (50 nm) / P3HT: PCBM (100 nm) / Al (200 nm). We investigated surface morphology, conductivity, and light transmission of the PANI thin film from different aniline monomer concentration and studied the factors on device efficiency, also compared with the device structured with hole transport layer PEDOT:PSS.
In this study, we found PANI thin films synthesized with different aniline monomer concentration, their light transmission over 80% at the range of 450 nm ~ 650nm wavelength and the conductivity up to 0.6 S/cm. It shows that PANI thin film suitably act as hole transport layer. In addition, we found morphology of PANI thin film that varied with different aniline monomer concentration.
The power conversion efficiency of the device mainly affected by morphology with different aniline monomer concentration. Comparing to other parameters of concentration, the 0.3M aniline monomer concentration polymerized PANI thin film owned the most appropriate surface morphology, and the power conversion efficiency up to 1.76%.
