博士 === 國立交通大學 === 機械工程系所 === 104 === AZO thin films were deposited on soda lime glass by RF magnetron sputtering .Taguchi method with a L9 orthogonal array, signal-to-noise (S/N) ratio and analysis of variance (ANOVA) were employed to examine the performance characteristics of the coating operations. The grey-based Taguchi method showed that the electrical resistivity of AZO films is about 3.33×10-3 Ω-cm, and the visible range transmittance is about 87.64 %. Furthermore, by applying a very thin Al2O3 buffer layer with the thickness of 10 nm. The lowest electrical resistivity was 2.64×10-3Ω-cm. A thin TiO2 compact layers which is by means of radio frequency (rf) magnetron sputtering coating ensures higher photo catalytic activity and increased dye-sensitized solar cells (DSSC) conversion efficiency. It can prevent charge recombination and a higher short circuit current density. The experimental results show that the DSSC conversion efficiency is critically affected by the thickness of the compact TiO2 layer. CIGS thin film solar cells are coated on SUS430 which is flexible. CIGS thin film solar cells are coated on MoNa and Mo films back contact which is made form Direct current (DC) magnetron sputtering system. The electrical, adhesion, structural and morphological properties were analyzed that the thickness was fixed at 1000 μm. Above of all, the best conversion efficiency (η) reaches 8.71 %
