Purpose and goal
As for this project, we intend to fabricate high conductivity and high transparent PEDOT:PSS electrode for organic electronic devices applications. We have three aims and objectives listed as following: 1) Fabricate high conductivity and high transparent flexible PEDOT:PSS electrode for high performance electronic devices. 2) Increase the understanding on PEDOT:PSS conductive mechanism. 3) Fabricated high performance all-plastic organic solar cells and flexible supercapacitor.
Expected results and effects
According to this project, we have realized the highly conductive and flexible PEDOT:PSS electrode on PES substrate combined with one of the highest conductivity over 2600 S/cm and transparency over 85%. All-plastic organic solar cells based on this PEDOT:PSS electrode demonstrate a high power conversion efficiency over 4.0% with a structure of PES/PEDOT:PSS/PEI/P3HT:ICBA/PEDOT:PSS-T. Flexible Semi-transparent supercapacitor based on this electrode displays superior power density over 19000 W/kg and energy density over 3.40 Wh/kg.
Planned approach and implementation
Firstly, for realizing high conductivity PEDOT:PSS electrode, sulfuric acid is employed and diluted for realizing both high conductivity and feasibility on flexible substrates. Secondly, BSEM methods are employed for investigating the PEDOT and PSS arrangement in the composite film. Third, film transfer lamination method has been applied to fabricate all-plastic organic solar cells.
