摘要:
A glass having a visible transmission of no greater than 28% and low IR transmission, and employing a colorant portion: total iron (expressed as Fe2O3):0.7 to 1.8% cobalt oxide (e.g., Co3O4):0.001 to 1.0% titanium oxide (e.g., TiO2):0.25 to 3.0% selenium (e.g., Se):0 to 0.0020% chromium oxide (e.g., Cr2O3):0 to 0.010%.
摘要:
A technique of manufacturing glass having fairly clear color and/or high visible transmission is provided. In certain example embodiments of this invention, it has surprisingly been found that by using carbon-containing compound(s) including CxHyOz.mH2O, excellent melting and refining can be achieved in the manufacture of glass, and not as much ferrous iron is formed compared to the use of elemental carbon as a refining agent. Such compound(s) are especially advantageous when highly transparent clear glass is desired, in that less ferrous iron is formed and thus transmittance and coloration can be improved.

摘要:
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.

摘要:
A high transmission and low iron glass is provided for use in a photovoltaic device such as a solar cell. The glass substrate may be patterned on at least one surface thereof. In certain example embodiments, a combination of lithium oxide, antimony oxide, and salt cake is used in the glass to improve the refining conditions by lowering the melting temperature of the batch, thereby resulting in a quicker seed free time in the manufacturing process.
