Surface-Plasmon Enhanced Organic Thin-Film Solar Cells

摘要

The effects of surface plasmon on the performance of organic solar cells were investigated. Metallic nanoparticles fabricated using thermal anneal and Nanosphere lithography were experimentally and theoretically studied to understand their corresponding surface plasmon resonance. Near-field Scanning Optical Microscopy (NSOM) was used to investigate the strength of the optical near-field that is very close to the metal nanoparticles when illuminated with light that was resonant to the metal nanoparticles. NSOM measurements revealed great electric fields created due to the effects of surface plasmon of metal nanoparticles. Integration of selected metal nanoparticles and organic thin film were investigated. Further investigation of the plasmonic-enhanced photonic devices is emphasized as future goal as well as the development of Nanosphere lithography. A fast and economic nanofabrication technique will find a suitable application in the optoelectronic industry. The results from this research will greatly improve the understanding of the plasmonic-enhanced photonic devices and find new application in the development of future technologies.
