碩士 === 國立交通大學 === 照明與能源光電研究所 === 104 === In this thesis, optical properties and application in nanoparticles and quantum dots are investigated. Including gold nanoparticles (Au NPs) of specific optical properties, titanium nitride nanoparticles (TiN NPs) of the novel plasmonic material, silicon nanoparticles (Si NPs) with high refractive index in visible and near-infrared wavelength, and cadmium telluride quantum dots (CdTe QDs) with emission wavelength in visible and near-infrared region. In this study, we can effectively improve the device’s efficiency enhancement from doping amount of Au NPs with an average diameter 50 nm in the PEDOT:PSS hole transport layer so as increase surface roughness and reduce hole-electron combination rate. We present a method to construct NPs-QDs complexes to study near enhancement of exciton-plasmon interactions. In future, we expect to obtain higher performance solar cell through particular scattering property of silicon and titanium dioxide nanoparticles.
