| Research Abstract |
Surface free electrons of silver and gold nanoparticles can couple with the electric field of UV-near IR region, generating extremely enhanced localized electric fields at the surface region. This leads to strong interactions of photons and molecules, and then enhancement of photoelectric conversion efficiency based on photoinduced electron-transfer reactions. These nanoparticles showing plasmonic effects are called plasmonic nanoparticles. In this project, we have fabricated photoelectric conversion units (half cells), and have analyzed the requisites for improving the photoelectric conversion efficiency and for evaluating the optimum conditions. Furthermore, we have succeeded in incorporating plasmonic nanoparticles into organic thin film solar cells. By evaluating the performance of various types of fabricated solar cells, we have verified the enhancement based on plasmon.
