Researchers' Work from Shanghai Jiao-Tong University Focuses on Organic Electronics (Photolithographic patterning of PEDOT:PSS with a silver interlayer and its application in organic light emitting diodes)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Research findings on Organic Electronics are discussed in a new report. According to news reporting out of Shanghai, People's Republic of China, by VerticalNews editors, research stated, "A patterning scheme for poly(3,4-ethylenedioxythio-phene):poly(styrenesulfonate) (PEDOT:PSS) is reported. With a silver interlayer, the conductive PEDOT:PSS film can be patterned down to micrometer scales by traditional photolithography, and this patterning scheme can be applied on large-area flexible substrates."

Our news journalists obtained a quote from the research from Shanghai Jiao-Tong University, "Through systematical investigations, the patterning processes have no obvious influence on both the bulk and surface properties of PEDOT:PSS films. Efficient organic light emitting diodes (OLEDs) are realized based on this patterned PEDOT:PSS anode, and they show comparable performance to those devices with an indium tin oxide (ITO) anode. High-resolution OLED pixel arrays are also demonstrated. Our interlayer approach here has an advantage of patterning PEDOT:PSS with high resolution and large scale, and it is also compatible with traditional photolithographic processes which substantially save the capital cost."

According to the news editors, the research concluded: "Results indicate that the photographically patterned conductive PEDOT:PSS film becomes a promising candidate for eletrical eletrode material in organic electronic applications."
