| Summary: | 碩士 === 國立中正大學 === 光機電整合工程研究所 === 101 === In our study, we sputtering a metal nano structures on the surface of absorption layer (CIGS layer) and TCO layer (AZO layer) of CIGS Solar Cell, and then annealing so that the metal nano structures on the substrate will become a nano particle or nano island. We using scanning electron microscope and atomic force microscope to observe the metal nano particle’s shape and size to compare the transmittance and absorbance spectrums, then we can find out the optical properties of nano particles.
We find out that the sample which annealing with Ag 5nm thickness and temperature 350℃ has the highest peak and the best average transmittance rates, which the peak is at 340nm has 146.97％ and the average transmittance rate about 74.7%, though the sample’s transmittance do not higher than the reference, but at the wave band (about 300-400nm ), the transmittance has a peak higher than the reference, we speculate that is because of the LSP resonance effect enhancement. About samples of CIGS, because the metal Ag and Au will interact with CIGS when annealing, so we can’t distinguished the shapes and size with SEM and AFM.
