  7. Abstract:
  8. Thin film of Indium oxide doped with tin is used as a transparent electrode for different applications like screening panels, solar cells, touch panels and elechtrochromic tools. Trading thin films of ITO are precipitated using sputtering. However sol gel method can be simple and economic to make transparent electrodes. In this thesis first ITO sols is prepared using Indium nitrate and tin chloride with two or four capacities due to the production of transparent oxides on soda lime glass. Then the effect of tin chloride with two and four capacities is investigated on resistance and optic properties. Results show that tin chloride with four capacities in comparison with tin of two capacities highly reduces the electrical resistance and it increases the transparency in the visible range of light. Improvement of the characteristics of these layers is one of the problems in the application of this transparent conductive oxide. Therefore in the second part of the thesis the effect of the different dopants, concentration of the dopant and the temperature of heat treatment on the electrical and optical properties of the ITO thin films is considered. Dopants of copper and chrome oxide with three capacities, silver and gold with tungsten oxide were used. Among these dopants gold with tungsten oxide decreases the electrical resistance from10 KΩ/Sq to 959 Ω/Sq and reduces the transparency from 88.5% to 60% and consequently can be considered as the best choice
