本論文中使用Poly(3-hexylthiophene) (P3HT)為電荷施體(Donor)及[6,6]-phenyl-C61- butyric acid methyl ester (PCBM)為電荷受體(Acceptor)材料，以摻混的方式溶於氯苯(Chlorobenzene)，將其應用於高分子太陽能電池，其元件結構如下：ITO / PEDOT:PSS / P3HT:PCBM / Al 在AM1.5G 100mW/cm2的模擬太陽光源下量測。在穩定製程中基礎元件回火後功率轉換效率可達2%。
為了增加電洞傳輸能力，將高導電率的PEDOT nanorods塗佈於電洞傳輸層及有機主動層之間作為陽極介面層，其元件結構如下：ITO / PEDOT:PSS / PEDOT nanorods / P3HT:PCBM / Al 配製不同濃度之PEDOT nanorods層對元件效率有不同的提升，當濃度為1wt%時，PEDOT nanorods約可提升陽極緩衝層導電率一倍，進而使得元件短路電流密度提升170%，元件功率轉換效率可自2%提升至2.63%，提升幅度為30%。
因此使用PEDOT nanorods作為陽極介面層，應用於有機高分子太陽能電池元件上，確實有提升功率轉換效率的效果。探討其改善原因為PEDOT nanorods的添加使得導電率增加，造成短路電流密度增加，最後提升整體有機高分子太陽能電池元件的功率轉換效率。

In this study, P3HT and PCBM were used as donor and acceptor materials for polymer solar cells. The standard device was constructed of ITO / PEDOT:PSS / P3HT:PCBM / Al and the power conversion efficiency of 2% was achieved under AM1.5G 100mW/cm2 illumination.
In order to increase the hole transporting ability, we used PEDOT nanorods with high conductivity as an anode interlayer between the PEDOT:PSS and the P3HT:PCBM layer, with a configuration of ITO / PEDOT:PSS / PEDOT nanorods / P3HT:PCBM / Al.
According to experimental results. PEDOT nanorods dispersed well on the PEDOT:PSS surface through the spin-coating process. As the concentration of PEDOT nanorods 1wt% casting film, the conductivity of anode buffer layer raised about two times and the power conversion efficiency of device reached 2.63%. The short-circuit current and the power conversion efficiency of the polymer solar cell containing 1wt% PEDOT nanorods were obtained about 170% and 30% increasement, respectively.
In conclusion, it is quite useful to apply the PEDOT nanorods into polymer solar cells as an interlayer. The improvement in the short-circuit current which resulted in an enhancement of the power conversion efficiency originated from the increased conductivity of the buffer layer.
