NOVELTY - A glass (S1) comprises: 60-65 mol.% of silica (SiO2); 8-12 mol.% of alumina (Al2O3); 7-15 mol.% of boron trioxide (B2O3); 0-8 mol.% of alkali metal oxide; and 9-15 mol.% of alkaline earth metal oxide; where the glass has a coefficient of thermal expansion of 4-7.5 parts per million (ppm)/ degrees C from 25-300 degrees C.    USE - In photovoltaic module (claimed); and in semiconductor-based applications such as photovoltaics, photochromics, electrochromics, and organic light emitting diode applications.    ADVANTAGE - The alkalis in the glass and low melting temperature combine to accelerate melting, thus enabling high volume, low-cost melting and forming relative to alkali-free alternatives while retaining competitive properties including mechanical and dimensional stability when reheated to high temperature. The glasses are well suited for large-volume sheet glass applications, particularly organic light emitting diode (OLED) lighting and cadmium telluride (CdTe) photovoltaics, for which thermal stability, large volumes, and low cost are desirable substrate attributes.    DETAILED DESCRIPTION - A glass (S1) comprises: 60-65 mol.% of silica (SiO2); 8-12 mol.% of alumina (Al2O3); 7-15 mol.% of boron trioxide (B2O3); 0-8 mol.% of alkali metal oxide (M'2O); and 9-15 mol.% of alkaline earth metal oxide (RO); where the glass has a coefficient of thermal expansion of 4-7.5 parts per million (ppm)/ degrees C from 25-300 degrees C.
