Functional Polymers: Enhanced Performance for Polymer Solar Cells by Using Surfactant-Modified PEDOT:PSS as the Anode Buffer Layer
G. Fang, S. Wu, Z. Xie,* Y. Geng, L. Wang
A modified PEDOT:PSS is prepared by doping with a small amount of cationic surfactant of CTAB. XPS results show the insulating PSS enrichment on the top surface of the PEDOT:PSS layer is restrained by this doping. By using the CTAB-modified PEDOT:PSS instead of PEDOT:PSS as the anode buffer layer, the power conversion efficiency of the P3HT:PCBM bulk heterojunction solar cells is increased about 50% and an efficiency of 4.4% is achieved.
