- Abstract
The nanoparticle Au/TiO2embedded system plays a very important role in the plasmonic solar cell. The features of the nanoparticle embedded system will determine light enhancement, light absorption, scattering and localized surface plasmon resonance (LSPR), aiming to enhance the efficiency of the plasmatic solar cell. The characterizations of nanoparticles Au/TiO2embedded system consist of many parameters: the sizes of nanoparticles (Au, TiO2), the weight ratio of Au to TiO2, the thickness of the single layer or multilayer of Au/TiO2, the arrangements of Au and TiO2nanoparticles in integrated-matrix system, the light absorption, scattering and LSPR capacities of the Au/TiO2system. These parameters, however, depend on the technological conditions, the structure of plasmonic solar cell as well as the used substrate materials. This paper presents some technological developments for nanoparticles Au/TiO2embedded systems by different methods, including the preparation of the mixer Au/TiO2solutions and fabrication of the nanoparticle Au/TiO2systems with different Au percentages on several substrates (glass/ITO and AAO(Al)/Si.), and measured results of the morphological, structural and optical properties using FESEM, EDX, UV-vis spectroscopy. The comparisons of experiment results between different technology conditions and substrates (glass/ITO, AAO(Al)/Si.) are also shown and discussed with the aim of choosing the suitable technological process and technological conditions for application in the plasmonic solar cell.
