New Optoelectronics Findings from Karlsruhe Institute of Technology Reported (Aerosol jet printed top grids for organic optoelectronic devices)

September 10, 2014

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Investigators discuss new findings in Optoelectronics. According to news reporting out of Eggenstein Leopoldshafen, Germany, by VerticalNews editors, research stated, "Aerosol jet deposited metallic grids are very promising as transparent electrodes for large area organic solar cells and organic light emitting diodes."

Our news journalists obtained a quote from the research from the Karlsruhe Institute of Technology, "However, the homogeneity and the printing speed remain a challenge. We report homogeneous and rapidly printed metallic lines based on a complex-based metal-organic silver ink using a processing temperature of 140 degrees C. We show that inhomogeneities, which are present in printed structures at increased printing speeds and mainly caused by drying effects, can be improved by adding high boiling point solvents."

According to the news editors, the research concluded: "We demonstrate solution processed highly conductive and transparent hybrid electrodes on inverted organic solar cells comprising digitally printed top silver grids."
