Yttrium-doped zinc oxide (YZO) thin films were deposited with the dip coating technique. The effect of different sol-gel stabilizers (lactic acid with hydrolysis, without hydrolysis, and diethanolamine (DEA)) on structural, electrical and optical properties of the produced films were investigated. The stability of solutions prepared with DEA was much higher than that of other stabilizers. Films deposited using this solution also exhibited good adherence to the substrate, preferential orientation, and the lowest full width at half maximum of (002) X-ray diffraction peak. Average transmittance in the visible region increased by 14.6% and resistivity decreased by two orders of magnitude as the stabilizer was changed from lactic acid to DEA. The lowest resistivity, 3.5 ?10-2 źcm, and an average transmittance of 85% are obtained for 200 nm thick films annealed at 450 C in air using DEA as a stabilizer.
