As a flexible and portable power source, interests in solution processable polymer solar cells (PSCs) have been increased. Generally, transparent indium tin oxide (ITO) is used as electrode to demonstrate excellent performance, but the use of expensive indium and complicated vaccume process to produce ITO is not suitable to cost-efficient PSCs. For the above reasons ITO-free PSCs is becoming more interest, and as a substitute for ITO, studies on poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) have been performed due to its high transparency in the visible range, solution processability, and high mechanical flexibility. In this study, we fabricated highly conducting PEDOT:PSS electrode by sequent brush painting of PEDOT:PSS and polar solvent such as dimethyl sulfoxide (DMSO). Electrical, structural, and optical properties were characterized and their effect on the performance will be discussed. |
