本研究利用酸處理方式提高導電高分子PEDOT:PSS薄膜的導電度，並其當作陽極應用於有機太陽能電池，用來取代傳統陽極ITO，若搭配塑膠基板，將可發展製作可撓式有機太陽能電池。
將PEDOT:PSS薄膜以鹽酸、硫酸、磷酸等酸進行處理，比較並探討其導電度提升幅度之差異。其中以鹽酸提升幅度最高，導電度從0.3(S/cm)提升到了1109(S/cm)，提高了四個數量級。
在本研究中，我們探討不同酸處理對薄膜穿透率、導電度、表面型態、表面粗糙度以及穩定度，進而將其作為陽極製成有機太陽能電池，並觀察其薄膜特性對於元件效率的影響。結果發現，經過酸處理後的PEDOT: PSS薄膜，其導電度、表面形態、表面元素組成、表面粗糙度及穩定度會產生變化，但並不影響透光度。
最後將經過酸處理PEDOT:PSS薄膜當作陽極製成元件，元件結構為PEDOT:PSS(PH1000)(40nm)/PDEOT:PSS(AI4083)(65nm)/P3HT:PCBM(100nm)/
Al(200nm)，元件面積為0.16cm2，在AM 1.5G 100mW/cm2的模擬太陽光源照射下，其最高光電轉換效率高達1.32%，與未經酸處理之PEDOT: PSS陽極元件(0.21%)相比，光電轉換效率已大幅提升，且相當接近於ITO陽極元件之效率(1.46%)。

An acid treatment was used to enhance the conductivity of conducting polymer PEDOT:PSS thin film which can be an anode in organic solar cell. The thin film of PEDOT:PSS was fabricated to replace the ITO layer for polymer solar cells as an anode to develop the flexible polymer solar cells.
After acid treatment for PEDOT:PSS thin film with hydrochloric acid, Sulfuric acid,and phosphoric acid, we investigated and compared with the difference of conductivity. Hydrochloric acid has the highest conductivity enhancement, and it changed from 0.3(S/cm) to 1109(S/cm).
In this research, we investigated the optical transmittance, conductivity, surface roughness, surface morphology, and stability, and discussed the factors that can influence the device efficiency. The conductivity, surface roughness, surface morphology, and stability of the PEDOT:PSS thin film varies with acid treatment.
The devices were fabricated using an acid treated PEDOT:PSS thin film for an anode. The device structure is PEDOT:PSS(PH1000)(40nm)/
PDEOT:PSS(AI4083)(65nm)/P3HT:PCBM(100nm)/Al(200nm),and the device area is 0.16 cm2.The highest power conversion efficiency(PCE) is up to 1.32%. A large improvement over that of the unmodified organic solar cell (0.21%). It is comparable to that of using ITO as electrode ca. 1.46%.
