NOVELTY - A glass composition comprises (wt.%) silica (SiO2) (67-75), sodium oxide (Na2O) (10-20), calcium oxide (CaO) (5-15), total iron (expressed as ferric oxide (Fe2O3)) (0.001-0.05), % iron(II) oxide (FeO) (less than or equal to 0.0038), glass redox (less than or equal to 0.12) and antimony oxide (0-0.01), where the glass at a reference thickness of 4 mm has visible transmission of at least 91%, a transmissive a color value of -1-1, transmissive b color value of 0-1.5, % total solar (TS) of at least 90%, and a UV transmission of at least 80%.    USE - In a solar cell (claimed).    ADVANTAGE - The composition comprises a high transmission low iron glass, which is highly oxidized with glass redox not greater than 0.12, permitting the glass to realize a combination of high visible transmission, high infrared (IR) transmission, and high total solar (TS) transmission. The glasses for substrate achieve desired features of fairly clear color and/or high visible transmission, with slightly positive b color, while not requiring iron to be eliminated from the glass composition. Moreover, high % UV and high % TS values are also achieved, which is advantageous for solar cell applications in that more radiation is permitted through the glass substrate so that it can be converted to current or voltage.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a solar cell comprising glass substrate; and first and second conductive layers with at least a photoelectric film provided between them, where the glass substrate is of a composition comprising (wt.%) SiO2 (67-75), Na2O (10-20), CaO (5-15), total iron (expressed as Fe2O3) (0.001-0.05), %FeO (less than or equal to 0.0038), glass redox (less than or equal to 0.12), antimony oxide (0-0.01), and cerium oxide (0-0.2), where the glass substrate has visible transmission of at least 91%, a transmissive a color value of -1-1, transmissive b color value of 0-1.5, %TS of at least 90%, and a UV transmission of at least 80%; and    (2) a method of making the glass composition involving providing a glass batch that is processed so as to result in a glass comprising: (wt.%) SiO2 (67-75), Na2O (10-20), CaO (5-15), total iron (expressed as Fe2O3) (0.001-0.05), %FeO (less than or equal to 0.0038), glass redox (less than or equal to 0.12), where the glass batch has a batch redox of +12 to +30 during the processing of manufacturing the glass so that the resulting glass is highly oxidized and has a glass redox of not greater than 0.12.
