Preparation of organic-inorganic composite Indium Tin Oxide (ITO) foam and spongy ITO by sol-gel process is presented. The preparation process includes doping of Sn in In2O3 (In; Sn = 99; 01 to 90;10) in precursor sol (4-8 wt % equivalent metal oxides content) starting from an aqueous solution of metal salts and an organic binder. This newly made spongy porous ITO foam possesses relatively high electrical conductivity and may have potential applications in various fields, including DSSC and QD-based organic-inorganic hybrid solar cell which presently belongs to the frontier research area as an energy-related system.
