PROBLEM TO BE SOLVED: To provide a glass useful for low temperature applications, for instance, photovoltaic and OLED light applications.SOLUTION: Sodium-containing aluminosilicate and boroaluminosilicate glasses are described herein. The glasses can be used as substrates for photovoltaic devices, for example, thin film photovoltaic devices such as CIGS photovoltaic devices. These glasses can be characterized as having strain points of 540°C or more, thermal expansion coefficient of from 6.5 to 9.5 ppm/°C, as well as liquidus viscosities in excess of 50,000 poise. As such they are ideally suited for being formed into sheet by the fusion process.SELECTED DRAWING: None 【課題】低温用途、例えば、光起電用途およびＯＬＥＤ照明用途に有用なガラスを提供する。【解決手段】ナトリウム含有アルミノケイ酸塩およびアルミノホウケイ酸塩ガラスがここに記載されている。これらのガラスは、光起電装置、例えば、ＣＩＧＳ光起電装置などの薄膜光起電装置のための基板として使用できる。これらのガラスは、５４０℃以上の歪み点、６．５から９．５ｐｐｍ／℃の熱膨張係数、並びに５０，０００ポアズ長の液相線粘度を有すると特徴付けられる。それゆえ、それらのガラスは、フュージョン法により板に成形するのに理想的に適している。【選択図】なし
