The invention relates to a method for producing UV polarizers, according to which spheroid particles situated near the surface of the glass are incorporated into the support material (primarily standard float glass) in a novel arrangement. According to the method for producing UV polarizers, after the introduction of metal ions (e.g., silver ions) into the glass surface, a large size distribution of particles is achieved by multiple alternation of a heat treatment for separating out spherical metal particles, followed by the renewed introduction of metal ions and a subsequent heat treatment. A deformation of the glass produces spheroid particles of various sizes and different semi-axis relationships. The particles are characterized by their large size distribution and are deformed differently in relation to their spheroid shape. In this way UV polarizers are produced which have a wide absorption range since the absorption bands having different maximum positions overlap.

A method of manufacturing monolithic glass reflectors for concentrating sunlight in a solar energy system is disclosed. The method of manufacturing allows large monolithic glass reflectors to be made from float glass in order to realize significant cost savings on the total system cost for a solar energy system. The method of manufacture includes steps of heating a sheet of float glass positioned over a concave mold until the sheet of glass sags and stretches to conform to the shape of the mold. The edges of the dish-shaped glass are rolled for structural stiffening around the periphery.

Certain example embodiments of this invention relate to techniques for making a coated article including a transparent conductive indium-tin-oxide (ITO) film supported by a heat treated glass substrate. A substantially sub-oxidized ITO or metallic indium-tin (InSn) film is sputter-deposited onto a glass substrate at room temperature. The glass substrate with the as-deposited film thereon is subjected to elevated temperatures. Thermal tempering or heat strengthening causes the as-deposited film to be transformed into a crystalline transparent conductive ITO film. Advantageously, this may reduce the cost of touch panel assemblies, e.g., because of the higher rates of the ITO deposition in the metallic mode. The cost of touch-panel assemblies may be further reduced through the use of float glass.
