Printed Nanostructures for Organic Photovoltaic Cells and Solution-Processed Polymer Light-Emitting Diodes

Abstract

"We review the progress on printing-based technologies for organic electronic devices, especially organic photovoltaic (OPV) cells and polymer light-emitting diodes (PLEDs). First we discuss recent efforts to introduce interdigitated nanostructures on the order of tens of nanometers to the photoactive layers of OPV cells using nanoimprint lithography including a soft-printing process developed in our research group that can easily produce sub-20nm scale organic semiconductor nanopillars. Second, we review solution-processible printing technologies such as gravure printing, screen printing, blade coating, and slot-die coating for high-throughput manufacturing of PLEDs."
