ZnO thin films of 50 nm thickness have been deposited on uncoated glass substrates by the sol-gel spin coating method at 3000 rpm chuck rotation rate. After the deposition, the samples were annealed in open air at 3000C, 3500C and 4000C respectively. The effect of annealing temperature on the optical and electrical properties of the samples was investigated. It has been observed that the transmittance and the optical band gap vary with the annealing temperature. The resistivity and the sheet resistance were influenced by the annealing. Some of the samples can be used as window layer for solar cells and are also applicable in other opto-electronic applications.
