NOVELTY - A glass (A) comprises (wt.%): silicon dioxide (67-75), sodium oxide (10-20), calcium oxide (5-15), total iron (expressed as ferric oxide) ( less than or equal to 0.1), ferrous oxide ( less than or equal to 0.005), glass redox ( less than or equal to 0.08), antimony oxide (0 to less than 0.01), and cerium oxide (0-0.07); where the glass has visible transmission of greater than or equal to 90%, total solar (TS) transmission of greater than or equal to 90%; a transmissive aasterisk color value of (-1 to +1), and a transmissive basterisk color value of (-0.5 to +1.5).    USE - As a glass for forming a glass substrate in solar cell (claimed) and other photovoltaic devices. The solar cell is photovoltaic and/or thermal cell.    ADVANTAGE - The glass provides improved glass for solar cell substrate, as the glass is highly transmissive to visible light, fairly clear or neutral in color, and consistently realizes high % total solar (TS) values, and in turn permits the photovoltaic device to generate more electrical energy from incident radiation; by using an extremely high batch redox (such as 26-40, which is not typically used in making glass) in glass manufacturing process, which permits resulting low-ferrous glasses made via the float process to consistently realize a desirable combination of high visible transmission, substantially neutral color, and high % TS values; and further by using little or no cerium oxide, antimony, and/or arsenic. Thus a soda-lime-silica based glass is obtained with an extremely high batch redox. The glass/glass substrate has visible transmission of greater than or equal to 90%, TS transmission of greater than or equal to 90%, a transmissive aasterisk color value of (-1 to +1), and a transmissive basterisk color value of (-0.5 to +1.5). In making the glass via the float process, the high batch redox value tends to reduce or eliminate presence of ferrous iron (Fe2+; FeO) in the resulting glass, and permits the glass to have higher % TS transmission. These high batch redox values may be realized by adding sufficient oxidizers to the glass batch during float manufacturing process to cause batch redox to reach these levels. The high oxidation and thus high positive batch redox and/or glass redox ( less than or equal to 0.08) is achieved through the use of a combination of sufficient amounts of sulfates such as salt cake, Epsom salt, gypsum and/or nitrates such as sodium and/or potassium nitrates. The glass also avoids the use of undesired antimony oxidizer (0 to less than 0.01%) which is incompatible with certain float processes (e.g. tin bath); and also avoids the use of arsenic (which includes arsenic oxide (0 to less than 0.01)) which, like antimony tends to cause discoloration of cerium-doped glass. Also, there is no or very little cerium oxide (0-0.05, preferably not greater than 0.01)% in the glass that is a UV absorber, and prevents UV from transmitted through the glass; which is undesirable in certain solar cell. The colorant portion of the glass is substantially free of other colorants (other than potentially trace amounts) i.e. the glass composition is substantially free of erbium oxide, nickel oxide, cobalt oxide, neodymium oxide, chromium oxide, and selenium.
