	abstract = {In this work, thin films of aluminum doped ZnO (AZO) were deposited on ultrasonically cleaned\&nbsp;glass substrates\&nbsp;by\&nbsp;sol-gel process\&nbsp;using dip and spin\&nbsp;coating techniques. For this purpose, Zinc acetate dihydrate, aluminum nitrate nonahydrate, ethanol and mono\&nbsp;ethanolamine\&nbsp;were employed as precursor,\&nbsp;dopant, solvent and stabilizer, respectively.\&nbsp;X-ray diffraction, UV{\textendash}vis,\&nbsp;photoluminescence, 4-point probe and Van der pauw techniques were investigated for the characterization of the prepared AZO thin films.\&nbsp;X-ray-analysis\&nbsp;revealed that all the prepared films have hexagonal\&nbsp;wurtzite\&nbsp;structure with a relative preferential orientation along the c-axis and the\&nbsp;lattice parameters\&nbsp;are close to the standard values reported in literature.\&nbsp;UV{\textendash}vis spectroscopy\&nbsp;showed that the average value of the films{\textquoteright}\&nbsp;transmittance\&nbsp;in the visible region is found to be around 85\% and the gap ranges in the interval [3.15 eV{\textendash}3.30 eV]. The photoluminescence spectrum only showed the UV peak while the broad band of the visible region was completely vanished. The electrical measurements indicate that sol-gel methods provide relatively high\&nbsp;resistivities\&nbsp;compared to those obtained with physical\&nbsp;vapor deposition\&nbsp;(PVD) techniques.},
