CONSTITUTION: The glass has a coefficient of thermal expansion alpha20/300 of between 2.8 x 10¬-6/K and 3.8 x 10¬-6/K, which has the composition(in % by weight, based on oxide) of >58% to 65% of SiO2, >6% to 11.5% of B2O3, >14% to 25% of Al2O3, 4% to 8% of MgO, 0% to 8% of CaO, 2.6% to < 4% of SrO, 0% to < 0.5% of BaO, 0% to 2% of ZnO, and SrO + BaO >3%. The glass is free of arsenic oxide and antimony oxide, apart from unavoidable impurities, and can be produced in a float plant. The glass is used as substrate glass in thin-film photovoltaics.
