摘要:
This invention relates to a method of making soda-lime-silica based glass. In certain example embodiments, boron oxide (e.g., B2O3) is used in the glass for reducing the refining time (or increasing the refining rate) thereof. The boron oxide may be introduced into the glass batch or melt in the form of boric acid, sodium tetraborate pentahydrate, sodium tetraborate decahydrate, sodium pentahydrate, or in any other suitable form. In certain example embodiments, the resulting soda-lime-silica based glass ends up including from about 0.1 to 3%, more preferably from about 0.1 to 2.5%, and most preferably from about 0.5 to 2.0% (e.g., about 1%), boron oxide. It has been found that the use of boron oxide, and/or the form in which the same is introduced into the glass, is advantageous in that it permits the refining time of the glass to be substantially reduced.

摘要:
A soda-lime-silica based glass composition for manufacturing on a float line that has a faster refining rate due to the introduction of alkali earth oxides such as BaO, ZnO and/or SrO in the amount of from about 1-4% in total. These oxides replace part or all of the MgO in the base glass composition thereby decreasing the overall MgO content in the glass composition to about 2% or less. The glass can realize a lower viscosity at high temperatures so that refining of the melt may occur faster.

A patterned glass substrate is provided for use in a solar cell. The glass substrate is both patterned on at least one surface thereof and has a low iron content. The combination of low iron content, optional oxidizing agent, and the patterning of the glass substrate results in a substrate with high visible transmission and excellent light refracting characteristics.

Certain example embodiments of this invention relate to a high transmission low iron glass, which is highly oxidized and made using the float process, for use in photovoltaic devices such as solar cells or the like. In certain example embodiments, the glass composition used for the glass is made via the float process using an extremely high and positive batch redox in order to reduce % FeO to a low level and permit the glass to consistently realize a combination of high visible transmission (Lta or Tvis), high infrared (IR) transmission, and high total solar (TS) transmission. The glass substrate may be patterned or not patterned in different example embodiments of this invention.

A high transmission and low iron glass is provided for use in a solar cell. The glass substrate may be patterned on at least one surface thereof. Antimony (Sb) is used in the glass to improve stability of the solar performance of the glass upon exposure to ultraviolet (UV) radiation and/or sunlight. The combination of low iron content, antimony, and/or the patterning of the glass substrate results in a substrate with high visible transmission and excellent light refracting characteristics.

A high transmission low iron glass, that is highly oxidized, is provided for use in solar cells or the like. In certain example embodiments, the glass composition used for the glass is a low-iron type glass composition which is highly oxidized thereby permitting the glass to realize a combination of high visible transmission (Lta or Tvis), high ultraviolet (UV) and/or infrared (IR) transmission, and high total solar (TS) transmission. These features may be achieved without the need for antimony in certain example instances. The glass substrate used in a solar cell may be patterned in certain example embodiments of this invention.
摘要:
A high transmittance fairly clear/neutral colored glass composition is provided. An oxidizing agent(s) such as cerium oxide (e.g., CeO2) or the like is added to the glass batch in order to realize very oxidized conditions (i.e., to significantly lower the redox of the resulting glass). As a result of the oxidizing agent(s) used in the batch, the iron is oxidized to a very low FeO (ferrous state) content. For example, this may result in a glass having a glass redox value of no greater than 0.12 (more preferably
