Indium Tin Oxide (ITO) is a Ternary composition of indium, tin, and oxygen in varying proportions, primarily used as a Transparent conducting oxide in applications such as touchscreens, LCDs, and Solar Panels due to its Excellent electrical conductivity and Optical Transparency. Its unique properties make it indispensable in the manufacture of Electronic displays and Photovoltaic Devices, despite ongoing research into Alternative materials to Reduce costs and Reliance on indium.
