Abstract

A novel technique based on the two polymer micro-transfer molding (2-P mu TM) for fabricating one dimensional (1D) high aspect ratio nanoscale metallic structures is presented and experimental characterization is described. Glancing angle metal deposition and physical argon ion milling (etching) techniques were also employed in processing. The resulting metallic structures have high transmission (similar to 80%) in the visible spectrum and have superior electrical conductivity (resistance from 2.4-7.3 Omega) compared to standard indium-tin oxide (ITO) glass. Thus, the high aspect ratio metallic structures are a promising alternative with potentially superior performances to ITO glass as transparent electrodes for organic solar cells.
