An alkali-free aluminoborosilicate glass which has the following composition (in % by weight, based on oxide): silicon dioxide (SiO2) > 58 - <= 65, boric oxide (B2O3) > 6 - <= 10.5, aluminum oxide (A1 2O3) > 14 - <= 25, magnesium oxide (MgO) 0 - < 3, calcium oxide (CaO) 0 - 9, and barium oxide (BaO) > 3- <= 8, with magnesium oxide (MgO) + calcium oxide (CaO) + barium oxide (BaO) 8 - 18, and zinc oxide (ZnO) 0 - < 2, and which is highly suitable for use as a substrate glass both in display technology and in thin-film photovoltaics. |
