제목 Surface Texture 된 ZnO:Al 투명전도막의 제작 및 특성
초록 Low resistivity and highly transparent ZnO conducting films for thin film solar cell applications were fabricated at low temperature by rf magnetron sputter deposition. Al-doped ZnO films were deposited on Corning 2947 glass substrate at a substrate temperature of 200 ℃. Structural, electrical and optical properties of the ZnO:Al films were investigated in terms of the reparation conditions. After deposition, the smooth ZnO:Al films were etched in diluted HCl (0.5%) to examine the electrical and surface morphology properties as a variation of the time. The most important deposition condition of surface-textured ZnO:Al films by wet chemical etching is the etching time. The obtained films were polycrystalline with a hexagonal wurtzite structure and preferentially oriented in the (002) crystallographic direction. The transmittance of the ZnO:Al films in the visible range was over 90.7 %. The lowest resistivity for the ZnO:Al films were about 5.7Ιx10-4 Ω•cm , Al content of 2.5 wt% with a substrate for about 800 nm in film thickness.
