Studies on the properties of sputter-deposited Al-doped ZnO films

High-rate, room temperature plasma-enhanced deposition of aluminum-doped zinc oxide nanofilms for solar cell applications

“…The presence of a strong (0 0 2) diffraction peak indicates that the films have a marked (0 0 2) preferential orienta- tion since the (0 0 2) plane is the most closely-packed plane of the zinc oxide crystal [12]. There is a small difference in the diffraction angles from the standard angle of 34.45 • which appears to be due to the addition of aluminum to zinc oxide, this in turn leads to a slight distortion of the ZnO crystal lattice [19]. In the experiments, neither aluminum nor aluminum oxide characteristic peaks are observed in the XRD patterns.…”

“…Compared with undoped ZnO, the electrical conductivity, the charge carrier density and the mobility are substantially improved in Al-doped ZnO (ZnO:Al) films [19,20]. To date, many growth techniques such as magnetron sputtering, spray pyrolysis, metalorganic chemical vapor deposition, pulsed laser deposition, etc., have been employed to fabricate ZnO:Al [21][22][23].…”

Sintering of Transparent Conductive Oxides: From Oxide Ceramic Powders to Advanced Optoelectronic Materials

“…Although various studies of synthesis, characterization and application of Al:ZnO thin layer systems are given in the literature (Stanciu, et al, 2001, Selmi, et al, 2008, there are only a few investigations referring to synthesis and processing of nanosized Al:ZnO particles. Flame spray pyrolysis of liquid Al-ad Zn precursors led to uncontrolled Al:ZnO stoichiometries and segregations of the spinel and wurzite phase combined with evaporation of the metallic Zn phase (Kim, 2008).…”

Investigation of ultraviolet response enhanced PV cell with silicon-based SINP configuration

“…The average transmittance of the film is about 95% in the visible region. The absorption coefficient α was evaluated from the measurements of optical transmittance T according to the following relation [3]:…”
