摘要: Abstract ZnO: Ga thin films have been prepared by spin coating on glass substrate using solutions of zinc acetate dihydrate and gallium nitrate hydrate precursors in methanol, ethanol 2-methoxyethanol with mono-ethanolamine as complexing agent to examine the effect solvent their opto-electrical characteristics. The selection involves factors like toxicity, sol stability film properties. Accordingly, is shown be suitable for yielding a stable produce low cost 1 at% Ga−ZnO useful photovoltaic applications. These exhibit hexagonal structure (0001) preferred orientation, optical transmittance ∼75−96% wavelength range 400−900 nm, electrical resistivity of ∼ 3 × 10−2 Ω-cm electron mobility ∼24 cm2/ V. s.
