20100300535 | FUSION FORMABLE SODIUM CONTAINING GLASS - Sodium-containing aluminosilicate and boroaluminosilicate glasses are described herein. The glasses can be used as substrates for photovoltaic devices, for example, thin film photovoltaic devices such as CIGS photovoltaic devices. These glasses can be characterized as having strain points ≦540° C., thermal expansion coefficient of from 6.5 to 9.5 ppm/° C., as well as liquidus viscosities in excess of 50,000 poise. As such they are ideally suited for being formed into sheet by the fusion process. | 12-02-2010 |
20100300536 | FUSION FORMABLE SODIUM FREE GLASS - A compositional range of fusion-formable, high strain point sodium free, silicate, aluminosilicate and boroaluminosilicate glasses are described herein. The glasses can be used as substrates for photovoltaic devices, for example, thin film photovoltaic devices such as CIGS photovoltaic devices. These glasses can be characterized as having strain points≧540° C., thermal expansion coefficient of from 6.5 to 10.5 ppm/° C., as well as liquidus viscosities in excess of 50,000 poise. As such they are ideally suited for being formed into sheet by the fusion process. | 12-02-2010 |
20110100058 | FORMATION OF GLASS BUMPS WITH INCREASED HEIGHT USING THERMAL ANNEALING - The disclosure teaches methods of forming at least one bump in a glass substrate having a surface and a body portion. The method includes performing a first irradiation of a portion of the glass substrate to form in the glass surface the at least one bump having bump height. The method also includes performing thermal annealing of at least a portion of the glass substrate that includes the first irradiated portion. The method then includes performing a second irradiation of the bump to increase the bump height. | 05-05-2011 |
